SECTION —A
(READING)

Question. 1. Read the passage given below:

  1. Maharana Pratap ruled over Mewar only for 23 years. However, he accomplished so much grandeur during his reign that his glory surpassed the boundaries of countries and time turning him into an immortal personality. He along with his kingdom became a synonym for valour, sacrifice and patriotism. Mewar had been a leading Rajput kingdom even before Maharana Pratap occupied the throne. Kings of Mewar, with the cooperation of their nobles and subjects, had established such traditions in the kingdom, as augmented their magnificence despite the hurdles of having a smaller area under their command and less population. There did come a few thorny occasions when.the flag of the kingdom seemed sliding down. Their flag once again heaved high in the sky thanks to the gallantry and brilliance of the people of Mewar.
  2. The destiny of Mewar was good in the sense that barring a few kings, most of the rulers were competent and patriotic. This glorious tradition of the kingdom almost continued for 1500 years since its establishment, right from the reign of Bappa Rawal. In fact only 60 years before Maharana Pratap, Rana Sanga drove the kingdom to the pinnacle of fame/ His reputation went beyond Rajasthan and reached Delhi. Two generations before him, Rana Kumbha had given a new stature to the kingdom through victories and developmental work. During his reign, literature and art also progressed extraordinarily. Rana himself was inclined towards writing and his works are read with reverence even today. The ambience of his kingdom was conducive to the creation of high quality work of art and literature. These accomplishments were the outcome of a longstanding tradition sustained by several generations.
  3. The life of the people of Mewar must have been peaceful and prosperous during the long span of time; otherwise such extraordinary accomplishment in these fields would not have been possible. This is reflected in their art and literature as well as their loving nature. They compensate for lack of admirable physique by their firm but pleasant nature. The ambience of Mewar remains lovely thanks to the cheerful and liberal character of its people.
  4. One may observe astonishing pieces of workmanship not only in the forts and palaces of Mewar but also in public utility buildings. Ruins of many structures which are still standing tall in their grandeur are testimony to the fact that Mewar was not only the land of the brave but also a seat of art and culture. Amidst aggression and bloodshed, literature and art flourished and creative pursuits of literature and artists did not suffer. Imagine, how glorious the period must have been when the Vijaya Stambha which is the sample of our great ancient architecture even today, was constructed. In the same fort, Kirti Stambha is standing high, reflecting how liberal the then administration was which allowed people from other communities and kingdoms to’ come and carry out construction work. It is useless to indulge in the debate whether the Vijay Stambha was constructed first or the Kirti Stambha. The fact is that both the capitals are standing side by side and reveal the proximity between the king and the subjects of Mewar.
  5. The cycle of time does not remain the same. Where as the reign of Rana Sanga was crucial in raising the kingdom to the acme of glory, it also proved to be his nemesis. History took a turn. The fortune of Mewar the land of the brave, started waning. Rana tried to save the day with his acumen which was running against the stream and the glorious traditions for sometime.

Question.2. Read the passage given below:

  1. To ensure its perpetuity, the ground is well held by the panther both in space and in time. It enjoys a much wider distribution over the globe than its bigger cousins, and procreates sufficiently profusely to ensure its continuity for all time to come.
  2.  There seems to be no particular breeding season of the panther, although its sawing and caterwauling is more frequently heard during winter and summer. The gestation period is about ninety to hundred days (Whipsnade, ninety-two days). The litter normally consists of four cubs, rarely five. Of these, generally two survive and not more than one reaches maturity. I have never come across more than two cubs at the heels of the mother. Likewise, graziers in the forest have generally found only two cubs hidden away among rocks, hollows of trees, and other impossible places.
  3. Panther cubs are generally in evidence in March. They are born blind. This is a provision of Nature against their drifting away from the place of safety in which they are lodged by their mother, and exposing themselves to the danger of their being devoured by hyenas, jackals, and other predators. They generally open their eyes in about three to four weeks.
  4. The mother alone rears its cubs in seclusion. It keeps them out of the reach of the impulsive and impatient male. As a matter of fact the mother separates from the male soon after mating and forgets all about their tumultuous union. The story that the male often looks in to find out how the mother is progressing with her cubs has ho foundation except in what we wish it should do at least.
  5. The mother carries its cubs about by holding them by the scruff of their neck in its mouth. It trains them to stalk, and teaches them how to deliver the bite of death to the prey. The cubs learn to treat all and sundry with suspicion at their mother’s heels. Instinctively the cubs seek seclusion, keep to cover and protect their flanks by walking along the edge of the forest.
  6. I have never had an opportunity to watch mother panther train its cubs. But in Pilibhit forests, I once saw a tigress giving some lessons to its little ones. I was sitting over its kill at Mala. As the sun set, the tigress materialised in the twilight behind my machan. For about an hour, it scanned and surveyed the entire area looking and listening with the gravest concern. It even went to the road where my elephant was awaiting my signal. The mahout spotted it from a distance and drove the elephant away.
  7. When darkness descended upon the scene and all was well and safe the tigress called its cubs by emitting a low haa-oon. The cubs, two in number and bigger than a fu.ll- grown cat, soon responded. They came trotting up to their mother and hurried straight to the kill in indecent haste. The mother spitted at them so furiously that they doubled back its heels immediately. Thereafter, the mother and its cubs sat under cover about 50 feet (15 m) away from the kill to watch, wait, look, and listen. After about half an hour’s patient and fidgetless vigil the mother seemed to say ‘paid for’. At this signal, the cobs cautiously advanced, covering their flanks, towards the kill. No longer did they make a beeline for it, as they had done before.
  8. The mother sat watching its cubs eat, and mounted guard on them. She did not partake of the meal.

On the basis of your understanding of the passage complete the statements given below with the help of options that follow:
(a) To protect its cubs the mother panther hides them :
(i) among rocks (ii) in the branches of the trees
(iii) behind the tree trunks (iv) at its heels
(b) The male panther :
(i) is protective of its cubs (ii) trains its cubs
(iii) watches the progress of the mother
(iv) is impulsive and impatient
Answer the following questions briefly:
(c) How many cubs does the mother panther rarely deliver ?
(d) What may happen if the panther cubs are not born blind ?
(e) Why did the mahaut drive his elephant away ?
(f) Why did the tigress spit at its cubs ?
(g) From the narrators observation what do we learn about the nature of the tigress ?
(h) Why does the panther not face the risk of extinction ?
(i) Find words from the passage which mean the same as each of the following : 
(i) moving aimlessly (para 3)
(ii) came down/fell (para 7)
Answer.
(a) (i) among rocks
(b) (iv) is impulsive and impatient
(c) The mother panther delivers litter of four cubs, rarely five.
(d) If the panther cubs are not blind they drift away from the place of safety in which they are lodged by their mother.
(e) The mahaut drove away his elephant to protect it from the tigress.
(f) The mother tigress spitted at it cubs to call them back to its heels and watch the prey carefully, instead of running towards it in haste.
(g) The tigress is very protective about her cubs. She rears them alone without the help of the male. She trains them to hunt and guards them, while they eat.
(h) The panther does not face the risk of extinction because it procreates sufficiendy and profusely to ensure its continuity for all time to come.
(i) Moving aimlessly-drifting
(ii) came down/fell-descend

Question.3. Read the passage given below :
People tend to amass possessions, sometimes without being aware of doing so. They can have a delightful surprise when they find something useful which they did not know they owned. Those who never have to change house become indiscriminate collectors of what can only be described as clutter. They leave unwanted objects in drawers, cupboards and attics for years in the belief that they may one day need them. Old people also accumulate belongings for two other reasons, lack of physical and mental energy, and sentiment. Things owned for a long time are-full of associations with the past, perhaps with the relatives who are dead, and so they gradually acquire a sentimental value.
Some things are collected deliberately in an attempt to avoid wastage. Among these are string and brown paper, kept by thrifty people when a parcel has been opened. Collecting small items can be a mania. A lady cuts out from newspapers sketches of model clothes that she would like to buy if she had money. As she is not rich, the chances are that she will never be able to afford such purchases. It is a harmless habit, but it litters up her desk.
Collecting as a serious hobby is quite different and has many advantages. It provides relaxation for leisure hours, as just looking at one’s treasure is always a joy. One doesn’t have to go out for amusement as the collection is housed at home. Whatever it consists of- stamps, records, first editions of books, china-there is always something to do in connection with it, from finding the right place for the latest addition to verifying facts in reference books. This hobby educates one not only in the chosen subject, but also in general matters which have some bearing on it.
There are other benefits also. One gets to meet like-minded collectors to get advice, compare notes, exchange articles, to show off one’s latest find etc. So one’s circle of friends grows. Soon the hobby leads to travelling, perhaps a meeting in another town, possibly a trip abroad in search of a rare specimen, for collectors are not confined to one country. Over the years one may well become an authority on one’s hobby and will probably be asked to give informal talks to little gatherings and then, if successful, to larger audiences.
(a) On the basis of your understanding of the above passage make notes on it, using headings and subheadings. Use recognisable abbreviations (wherever necessary – minimum four) and a format you consider suitable. Also supply an appropriate title to it.
(b) Write a summary of the passage in about 80 words.
Answer. (a) Title: Collection-Advantage or dis-advantage 1. Notes .
(i) Consequences

Abbreviations Used
Hv have
Ppl people
Senti sentimental
Frnd friend
(b) Summary
People sometimes collect things due to various reasons which may be related to their need, lack of energy or sentimental value. Sometimes collection may be done to avoid wastage which later becomes mania. But it has many advantages too. It relaxes, amuses and educates. It has additional benefits where one may meet like-minded collectors to get advice, compare notes, exchange articles, to show off one’s latest find. As a result their friend circle grows bigger. In fact, hobby further leads to travelling.

Subject : Time to become aware- of the hazards of noise pollution
Dear Sir,
Through the esteemed columns of your prestigious newspaper, I, Karuna, a resident of New Delhi want to bring forth the issue of increasing noise pollution to the notice of the general public and concerned authorities. In the metro cities and big cities, there has been tremendous increase in the levels of noise pollution. It’s not only the shrieking horns and roars of vehicles but also marriage processions, loud playing DJ s, aircrafts and machines in industrial areas which cause lot of noise pollution. The consequences are extremely hazardous. They lead to increasing cases of deafness, insomnia, palpitation of heart, mental fatigue, etc. among the sufferers are the small babies and old people who can’t sleep properly, patients can’t rest and students can’t study. Then there are ‘Jagrans’ that force the public to keep awake the whole night. The problem further adds to the fact that noise control laws are neither followed properly nor implemented completely. The culprits bribe the police and other officials and get away safely.
So I think that law alone is not sufficient until and unless we citizens take an oath to make the city noise free and educate the people about its ill effects. Above all, everybody has a right to enjoy a noiseless rest and peace. Hope your newspaper will take initiative in this regard and relieve us from the menace of noise pollution.

Subject: Increasing cases of Road Rage ‘
Dear Sir,
I am writing this letter to bring to your kind notice the problem of increasing cases of road rage. Day by day it is becorhing a serious problem which should be sought over as quickly as possible. We often come across many incidents like minor scratch, a little push or a small brushing past leading to scuffles which sometimes result even in murder. Everyday there are many fatal accidents, the number of hit and run cases are also rising. In Delhi alone, 532 persons died in road accidents in the year 2014. It is observed that people are losing patience and tolerance power due to their modern lifestyle. They begin to fight over minor issues. The feeling of ignorance, irresponsibility, lawlessness and indifference is prevailing. Everybody is taking undue advantage of the freedom provided to them by the democracy.
Now it’s high time to realize the need of the hour. I hope the concerned authorities would realize the gravity of the situation and keep a check on these people and their activities either by imposing penalties or fines.

Question.6. ‘Brain drain is not a bane for a developing country like India’. Write a debate in 150-200 words either for or against the motion.
OR
Write a speech in 150-200 words on the topic, ‘Discipline shapes the future of a student. It is to be delivered in the morning assembly. You are Karuna/Karan.
Answer . ‘Brain Drain is not a bane for a developing country like India
Good morning, respected judges and the esteemed audience, I would like to speak For the Motion-’Brain Drain is not a bane for a developing country like India.
Brain Drain is a major problem of India that has been harmful for the country. Brain drain means the intelligent minds that do not get desirable jobs or recognition in their own country, fly away to other countries for better prospective where they are provided with favorable working conditions. They prove their intelligence there and are recognized throughout the world. They also become the pride of the country. Every year a large number of people go abroad either for acquiring higher studies or getting good jobs. It is because, their worth and intelligence is not counted in the country. Sometimes the most brilliant people also leave their India and prefer to stay in a well-developed country like America, London, Canada etc. This is most common in India as compared to other countries as the companies over here fail to provide necessary working conditions and best salaries to their own countrymen.
But the question arises “what if they show their worth in their own country?” How can they be stopped or fascinated to return to India ?
It is a matter of serious concern for the government of India because it is a complete loss for India. The professional training that the students receive in India and for which the government spends lakhs on them goes waste plus it is a gain for receiving countries. They can be attracted to India if the condition here are diverted to their attraction, if the merit and talent is given due consideration. Therefore, sincere efforts are required to bring them back by offering jobs according to their talent so as to make the country more efficient in all fields.

‘Discipline shapes the future of a student
Good Morning, honorable Principal, respected Teachers and dear friends. I am Karuna, student of class XII of your school; it is a great opportunity for me to share my views in today assembly on the topic ‘Discipline shapes the future of a student. The students of today are the citizens of tomorrow. They are the backbone of the society. They are going to be the future leaders, administrators and nation shapers. Student life is the time when their character is formed and takes shape. But now a days schools and colleges have become the place of complete indiscipline. Whether it is the morning assembly, annual function, sports meet or examinations, one can see complete indiscipline; Man is a social being and he lives and dies in a society. So he has to follow the rules of die society for which he has to discipline himself and this begins from the school only.
Aristotle said,” Discipline is obedience to rules formed by the society for the good of all”. Without discipline one cannot acquire knowledge and as the schools and colleges are abode of learning, it is required much over there. Students cannot gain much without discipline and the result can never be good. Thus, it is clear that the need of discipline is very much required in the student life. Indiscipline leads to failure and discipline paves the road of success.

Question. 7. Education has always been a noble profession. Our ancestors received their learning at gurukuls and ashrams. Even in the near past pathshalas (schools) were associated with places of worship. Today, education is fast becoming commercialised. Parents have to shell out a lot of money on coaching classes, tuition fees etc. Write an article in 150-200 words on ‘The State of Education, Today*. You are Karan/Karuna. 
OR
According to 2011 census, literacy rate of hundred percent or around has been achieved by only a couple of states in India. Illiteracy is found mostly among the old and the deprived sections of society. What can the youth do to spread literacy in society ? Write an article in 150-200 words on ‘Role of students in eradicating illiteracy’. You are Karuna/Karan.
Answer . The State of Education Today
By Karuna
Our ancestors have received their learning at gurukuls and ashrams. Pathshalas were regarded as the place of worship. But the scenario has completely changed now. Today education has been totally commercialized. .Whether its school or college, students have to rush to coaching classes and parents shell out a lot of money on them. They don’t rely on classroom teaching. On the other hand parents expectations from their children have increased. They want them to secure highest marks so as to get the highest paid jobs. They want them to become doctors, administrative officers, engineers etc. For this, they send their children to the most reputed schools; still they are not satisfied with their performance. So they want their child to get some extra knowledge to excel others in the line. Thus craze for coaching classes have been increased.
Another reason for joining the coaching classes is the inferiority complex which children face when they do not go for extra coaching. Although these so called coaching classes are just like the school classes because there also group teaching is done, still parents as well as children think them to be far superior to the classroom teaching. They should realize that these so called coaching classes are no better than money making business. The students must pay attention in class and must concentrate more on self-study.
OR
Role of students in eradicating illiteracy.
By Karuna
Youth plays a very important role in building the nation. With the increase in the population, the responsibilities of students have also increased. They are the pivot on which the development of any nation depends. We know that India is a land of villages and most of its population is illiterate. In most of the villages there are no schools or teaching facilities. Thus, villagers don’t get any opportunity to learn. Poverty and ignorance have deprived them from becoming literate. Therefore, it becomes the duty of the youth to render their services to them by teaching-them.They can give their valuable advice and guidance to educate them. We know that education helps in economic, social, spiritual and mental development. It broadens ones outlook towards society. Being illiterate or uneducated is like a curse. Students can help these people by organizing evening classes and by following the rule of ‘each one, teach one’. Out of their twenty four hours, the students can spare at least one hour for the unpriviledged people. They can create awareness among the illiterates regarding the hazards of overpopulation and recommend the need of keeping small family. Many NGOs and governmental agencies are there to assist these youths in this regard. They can be encouraged to do so by giving them additional marks or extra grades.
Youth, therefore can play a major role in making the country progressive and prosperous by bringing complete change in the attitude and thinking of the illiterate. So Jet’s join hands to eradicate illiteracy from our country.

Question.9. Answer anyfour of the following questions in 30-40 words each:
(a) What does the reference to chappals in ‘Lost Spring’ tell us about the economic condition of the rag pickers ?
(b) What do we learn about the crofter’s nature from the story, ‘The Rattrap’ ?

(e) How did the Governor, Oxford Prison describe Evans to the Secretary Examination Board ?
(f) At the dining table why did Zitkala-Sa begin to cry when others started eating ?
Answer . (a) The reference to chappals in ‘Lost Spring’ tells about the miserable life of the rag pickers setded in Seemapuri. Most of the impoverished children busy in rag picking were not wearing footwear. The boys were barefoot as it was a tradition to remain barefoot. It had become their habit not to wear chappals. But according to the writer it was their excuse • to conceal their poverty. .
(b) The crofter was a lonely old man who had no wife or a child. He wanted someone to talk to therefore, allowed the peddler to spend night at his house. He not only gave
‘ him shelter but also gave him food to eat and tobacco to smoke. He started a conversation with him’ and told him everything about himself and his earnings.
(c) The portrait of Shakespeare and the world map in the classroom of the slum children is far from the actual condition of the classroom. Shakespeare is the synonym
of knowledge and excellence but the children of the slum school have no .meaning for that. The map exhibits the world with all its bounties, whereas, for these children there is no world beyond poverty and hunger.Thus Shakespeare is wicked and the map a bad example.
(d) In the poem ‘Aunt Jennifer’s tigers’ we find the picture of a woman oppressed by the male chauvinism. She needs freedom from her burden some husband whose ring on her finger is like a handcuff which has snatched all her freedom and happiness.’ She has lot of constraints in her life because of her dominating husband and from whom she wants to get free.

(f) At the dining table, Zitkala-Sa heard a man’s voice and as she looked around to see him, she caught the eyes of a pale faced woman upon her. She wondered why she was so keenly watched by the strange woman. So as the third bell rang and everybody started eating, Zitkala began to cry as she could do nothing at that time.

Question.10. Answer the following question in 120-150 words :
Every teenager has a hero/heroine to admire. So many times they become role models for them. What is wrong if Sophie fantasizes about Danny Casey and is ambitious in life ?
OR
Our native language is part of our culture and we are proud of it. How does the presence of village elders in the classroom and M. Hamel’s last lesson show their love for French ?
Answers . It is a natural thing for teenagers to fantasize and dream. They don’t have much liabilities and burden at this stage of life so they are free to dream which is sometimes impractical and non-realistic. It is a part of their life bat sometimes these dreams have disadvantages also.
In the story ‘Going Places’, the author has described the feelings and dreams of such a girl, Sophie, who was a school going teenager. She was a day dreamer and fantasizes her future life with Danny Casey, a football player from Ireland. She dreamt of having met him twice in the arcade. For her, he was the hero to be worshipped.Then she thought of owning a boutique. She was blind to the bitter truth of life. She dreamt of an imaginary life, full of beautiful things. She also.dreamt of becoming an actress as there was a lot of money and fame in that profession. She wanted to be a fashion designer too. It can be said that she wanted to lead a lavish and grand life which was not possible. Her dreams were unrealistic in the sense that ultimately she would have to work in a biscuit factory. Thus we can say that she wanted to achieve the things which were quite impossible.

It was all due to the order from Berlin that from then onwards only German would be taught in the schools of Alsace and Lorraine instead of French. Then only the people realized how precious their language was to them. That day all the villagers occupied the back benches in the classroom to attend the last French lesson and to mark the respect for their French teacher, Mr. M. Hamel, who devoted his selfless service to the society. They felt very sad. They also regretted for not learning French properly. Franz was shocked to hear this news and Hamel’s words / were like thunderclaps to him. He was so sorry to have not learnt French before and for having wasted his time. His books suddenly became his friends. Even Mr. Hamel talked a lot about French language. According to him it was the most beautiful language in the world. It was the most logical one too. He asked his students never to forget this language.

Question. 11. Answer the following question in 120-150 words :
Both Derry and Lamb are victims of physical impairment, but much more painful for them is the feeling of loneliness. Comment.
OR
How did Jack end the Roger Skunk story ? How and why did Jo want to change it? .
Answers . A disabled or a handicapped person is considered to be an out caste. People sympathize with them but do not accompany them. They are excluded from the society. The feeling of loneliness and alienation is much more troublesome than the pain which disable people experience due to their physical impairment. This is very well revealed in the story, ‘On the face of it’, where the character, Derry has a burnt face and people often sympathized with him but it was not a heart felt one. This resulted in his pessimistic approach towards life. Derry had no association with the outer world till he met Mr. Lamb. Mr. Lamb’s attitude and outlook towards people and life appreciated him. He learnt to live a respectful life. Mr. Lamb inspired him to face the world in spite of his disability. Mr. ’ Lamb successfully infused in him courage and self-determination. He advised him to ignore the comments made by people on his physical impairment and enjoy the beauty of life and nature. Although the loneliness of Derry dominates the play, there are evident traces of Mr. Lamb’s loneliness also. The old man had no one to be with. He spent his day in the sun, reading books. By the end of the first scene, it becomes clearer that he is lonely when he mutters that no one comes back to him after meeting him the first time.

Jack used to tell his little daughter, Jo, bedtime stories. As soon as she grew older, she began to ask questions to her father. Once her father told her a story of a little animal called Roger Skunk who smelled awfully bad. He, therefore, met with a wizard who solved his problem with magic wand and made him smell like roses. But Skunk’s mother did not like it and took him back to the wizard to make him smell awfully bad once again.
This ending was not acceptable to Jo as she wanted the story to have another end in which the wizard should hit the mommy by his and magic wand leave Roger srunk emitting the pleasant smell of roses. Jo thought that Roger was the hero of the story so he must not look ugly or stinky. Jo’s perspective on life was different from her father’s. She wanted to change the end of the story to assert her views on her father. She had her own ideals and views which she wanted to be pursued.

Answer . Mrs. Hall was the owner of the inn ‘Coach and Horses’. She was very simple, friendly in nature and socialite woman. She felt very delighted and excited when Griffin came to stay at the inn as she was not expecting any guest in such a rough and harsh weather. She lit the fire herself to make her guest feel warm and cozy and went immediately to prepare meals for him with her own hands. A guest to stop at the inn, in the wintertime was an unheard piece of luck. Her maid Millie was sluggish so she carried the plates, cloth and glasses to the parlour on her own. She tried to begin conversation with him but as he was in no mood to talk, she immediately curtailed the conversation. She cooked eggs and ham, laid the table and did everything by herself. She also offered to take off his coat and hat for drying in the kitchen. For sympathy she asked her guest whether he had met with an accident or underwent an operation. Although her guest, Mr. Griffin showed no interest in her, she carried on her conversation and tolerated him as he gave her few gold coins for his stay at the inn without any bargain.

Through the columns of your esteemed daily, I, Karuna would like to emphasis on the importance of medical tourism. As we know that India is the most popular tourist place and sort after destination. People from all over the world come to India for their treatment by the most experienced and world class physicians. The medical facilities available in the high end hospitals of India are excellent. They are equipped with the latest technologies and the doctors are super specialized in their respective fields. With the advent of globalization, the world has shrunk. The concept of medical tourism was devised to help global citizens to enjoy their tourist sojourns while under cost effective, world class medical quality.
Over the last decade, India has emerged as the preferred destination for medical tourism. The city of Chennai has been termed as ‘India’s health capital’. India’s medical tourism sector is expected to experience an annual growth rate of 30%, making it a $2 Billion industry. Therefore, medical tourism should also be promoted by the government along with other tourist sectors.

Answer.
‘Importance of Public Transport’
By Karuna
Recently I heard that traffic police has started a new drive against the pollution causing vehicles. Traffic police is stationed at the important intersections. Each and every vehicle is checked for ‘No Pollution’ certificates and they are fined Rs.
500 for the lapse. But what is the use of all this and how long could it go because people find too many excuses for their negligence. Next, from every house minimum of two to three vehicles are used by the people for going to their working places. Sometimes they are stuck in their vehicles for long hours due to heavy traffic jams.
So it would be far better if the government provides public transport’ facilities. It would create a lot of convenience for the public and daily commuters. It has many social, economic and environmental benefits. Social benefits of using public transport are multifold. It helps in developing a sense of community among people. They feel a community connection with those who are traveling with them. It encourages people ‘ to have a healthy lifestyle if they walk to their station, stand or stop. Moreover, it is less stressful as it saves a lot of time. Then economic benefits include less expenditure of money on buying cars or spending money on its maintenance. Traveling by public transport is much cheaper than private transport. It also reduces pollution and road congestion thus, helping in environmental conservation.

‘Gender Discrimination In Society’
By Karuna
In India, attitude towards men and women has been discriminating since generations. Although,the Constitution of India has provided equal rights to men and women, gender disparity prevails. Nature has also divided human beings into two equal halves and both are given* equal responsibilities according to their capacity, thus, stating the rights to both of them. But we humans have shown discrimination which has now become a practice in society. The powerful become aggressor and the other faces the aggression. Usually women are considered to be weaker as compared to men and are supposed to be uncapable of doing everything just because of their fragile outlook. Gender discrimination prevails in many homes, it is generally seen in families where there are sisters and brothers and where brothers are favored over sisters. Female infanticide and female foeticide are still common in ‘ many regions of the country. Sexual harassments, eve teasing, bride burning, woman trafficking, dowry deaths and many more evils are being perpetrated. Economically females are less privileged as they do not have control oft*financial matters.
In the rural areas and villages the situation is still worse. There has been no change in the social, economic and family status of the women. They are subjected to exploitation, domination and harassment by their male counterparts. But now it’s time that women should be empowered and encouraged so that the gap between and men and women be reduced.

(b) Experience at YMCA swimming pool had a deep meaning for William Douglas; He had nearly escaped from drowning in the pool when he was sitting alone on the edge of the pool and a strong young man picked him up and tossed him into the pool. The experience had a deeper meaning for Douglas. He had experinced the fear of dying but at . the same time, he learnt the will to live which helped him to overcome the fear.
(c) The first day in the land of apples was a bitter cold one. The snow covered the ground and the trees were bare.

Answer.
‘The Internet cannot replace a classroom teacher’ Good morning, respected judges and the esteemed audience, today I have got the privilege of speaking in support of the Motion ‘The Internet cannot replace a classroom teacher’.
It is indeed a truth that internet can solve a bulk of problems and provides with all the necessary answers with illustrations to the students but it cannot replace a classroom teacher as it is devoid of any kind’of emotion which is very much required while teaching children. During teaching, teachers have to face all types of students with different mental labilities and thus they adjust their teaching pattern according to tjiem. They motivate their students accordingly and help the weaker section of students in coming up. There are some queries which cannot be solved by the internet but only a teacher can resolve it. The teacher understands the emotions and sentiments of the children; they realize the positive as well as negative feelings of the students. Teachers help us to remain alert and active in the classroom during teaching whereas a machine can never ‘ be. Besides, Internet can never beat the knowledge of human beings. It’s not necessary that all the information provided by internet is genuine. The question is that from where has all the information or knowledge on internet come? It is we humans only that has it into the computers.
In the end, 1 would like to say that a machine can never replace a living and breathing knowledgeable person.

‘Water, a valuable asset,
conservation at home and at school
Honorable Principal, respected Teachers and dear friends! Good Morning. I am Karuna, student of class XII. It is a great * opportunity for me to share my views on the topic ‘Water, a valuable asset, conservation at home and at school’ in today’s assembly.
Water scarcity today has become a big issue which if not dealt with in time, will turn out to be a hazard. With the increasing population, people are facing the problem of acute water shortage. People waste water in many ways which include washing cars, bathing animals, construction work, leaving taps running, etc. Apart from this, we can see leaking water pipes at many places which should be repaired at once. Children and women should be taught not to leave the taps running while brushing the teeth or washing utensils and clothes. At home, water used for washing fruits and vegetables can be used for gardening purpose.
To make the people aware to conserve water, importance of rain water harvesting and the method to recycle the water should be explained. Without water there is no life. Public should be encouraged to improve water management practices that reduce die wastage of water and enhance the beneficial use of , water. Some ancient methods of water conservation should also be practised. In case the water is not used wisely by anyone, then heavy fine should be imposed.

Importance of Yoga to Students By Karuna
Today’s sedentary lifestyle has given invitation to many’diseases where man has limited time to spare ‘ for his health. But practicing yoga helps to keep a person away from several health problems. It is the science that cures many serious diseases and helps the mind as well as body to remain sound. It helps in maintaining balance between mental and social status of a human being. With regular practice of yoga, we tend to become more sensitive to the kind of food our body asks. A few minutes of yoga helps in getting relief from stress. It helps detox the body and de-stress the mind. We all want to live in a peaceful atmosphere and surrounded by nature, but we hardly realize that peace can be found within us. Yoga is the best way to calm a disturbed mind. On the other hand, yoga postures massage organs and strengthen muscles; breathing techniques and meditation release stress and improve immune system. Yoga and meditation work on keeping the mind happy and peaceful. When we feel drained out of energy, a few minutes spend on yoga provides the freshness and energy. It also helps in improving body posture. Today, students face many problems due to burden of studies and feel depressed but yoga acts as the stress buster for them. In many schools yoga has been practiced on daily basis as a part of the curriculum. It is gaining popularity not only in India but in European countries also.
In the end I would like to tell that yoga is a continuous process, so keep practicing!

Advertisements as a source of information
By Karuna
Advertisements have become an inseparable part of our life. We can’t get away from them as they have surrounded us from all sides. Go out of the house and we can see various hoardings displaying one or the other things, switch on television and they start attacking us in between the serials and movies. Even news chinnels are interrupted by them. In all we can say that we can’t escape from the advertisements. .
But there are certain things.that can be said in favor of advertisements. The cost of production is lowered when the advertisers give the money to newspapers, magazines, radio and television. Advertising is a way of delivering proper message to the customers. This way we get the information as well as knowledge of various products. Advertisements help in drawing customers to the business. It benefits the consumers also as there is competition between the manufacturers and they try to sell their products at lower cost than the other. Buyers on the other hand get wider choice to select the product according to their pockets and taste. They inform us about all the new products which are launched in the market. Without them we would not be able to know about the new things and its benefits. Therefore, advertisements seek to generate increase in consumption of a product or a service by introducing it to the target consumers.

Question.20. How does industrial melanism support Darwins theory of Natural Selection ? Explain.
Answer: In England, before industrial revolution the environment was unpolluted. The white-winged moths were more and lichens on the barks of trees were pale. The white-winged moths could easily camouflage, while the darkwinged were spotted out by the birds for food. Hence, they could not survive. After industrial revolution the lichens became dark (due to soot deposit). This favoured the dark-winged moths while the white-winged were picked by birds. The population of the former which was naturally selected increased.

(c) Germ pores : Allow germination of pollen grain and formation of pollen tubes.

Question.23. How is the amplification of a gene sample of interest carried out using Polymerase Chain Reaction (PCR) ?
Answer: Polymerase chain reaction (PCR) is a method in which the desired gene is synthesised in vitro in following steps:

  1.  Denaturation : The double-stranded DNA is denatured by applying high temperature of 95°C for 15 seconds. Each separated single stranded strand now acts as template for DNA synthesis.
  2.  Annealing: Two sets of primers are added which anneal to the 3′ end of each separated strand. Primers act as initiators of replication.
  3.  Extension : DNA polymefase extends the primers by adding nucleotides complementary to the template provided in the reaction. A thermostable DNA polymerase (Taq polymerase) is used in the reaction which can tolerate the high temperature of the reaction. All these steps are repeated many times to obtain several copies of desired DNA.

Question.24. Trace the life-cycle of malarial parasite in the human body when bitten by an infected female Anopheles.
Answer : Plasmodium requires two hosts to complete its life cycle.When female Anopheles mosquito bites a healthy person. Sporozoite of Plasmodium gets into human blood through the bite of female Anopheles mosquito. The parasite multiply in liver cells and finally burst in liver cells and released in blood, then they get into red blood cells, where they further multiply asexually and burst in RBCs also and released toxic substance haemozoin (associated with fever and chills). After a while they change into gametocytes, which are picked up by the mosquitoes and the entire cycle occurs again.

The goal setting theory suggests that an effective tool for making progress is to ensure that participants in a group with a common goal are clearly aware of what is expected from them.

Question.9. Explain any two factors affecting wellness.**
Answer. Factors Affecting Physical Fitness
Beth has heard that kids today are less physically fit than ever, but why is this? Both long term and short term physical fitness are affected by a great number of factors, such as:

  • Injury – Any serious injury will have an adverse effect on a student’s physical fitness. When the body takes time to heal, it takes away opportunities to move and build strength, stamina and coordination.
  • Lack of physical activity – When Beth’s students show up at the gym, she can tell they’ve been spending more time in front of screens than they do on their feet. Increasing school demands, families with both parents working, neighborhoods with fewer parks, and cuts in school recess all mean that kids spend less time outside and moving, which results in overall lower fitness.
  • Poor diet/nutrition – The amount of fast food and quick options kids can grab has increased over the years. They seem to be eating more junk and fewer whole foods, which means they don’t get as much nutrition as they could. This results in an overall lower level of physical fitness. Beth knows its super important to teach her students about making healthy food choices.
  • Poor and inconsistent rest/sleep – Although it may seem contrary, rest is just as important to physical fitness as physical activity. The body needs to replenish and rebuild when resting.
  • Dehydration – Although there is no expert consensus definition of dehydration, being dehydrated will decrease both physical and mental performance. The body needs water to survive and thrive.

Question.10. ” Explain any two types of causative factors related to accidents in sports. **
Answer.
Causes:
Sports injuries are most commonly caused by poor training methods; structural abnormalities; weakness in muscles, tendons, ligaments; and unsafe exercising environments. The most common cause of injury is poor training. For example, muscles need 48 hours to recover after a workout. Increasing exercise intensity too quickly and not stopping when pain develops while exercising also causes injury.

Everyone’s bone architecture is a little different, and almost all of us have one or two weak points where the arrangement of bone and muscle leaves us prone to injury. Common predisposing factor in injuries to the ankles, legs, knees, and hips include:

  • uneven leg length
  • excessive pronation (flat feet)
  • cavus foot (over-high arches)
  • bowlegged or knock-knee alignment

Uneven leg length may lead to awkward running and increases the chance of injury, but many people with equal-length legs suffer the same effects by running on tilted running tracks or along the side of a road that is higher in the centre. The hip of the leg that strikes the higher surface will suffer more strain.

Pronation is the inward rolling of the foot after the heel strikes the ground, before the weight is shifted forward to the ball of the foot. By rolling inwards, the foot spreads the shock of impact with the ground. If it rolls too easily, however, it can place uneven stress on muscles and ligaments higher in the leg.

While an overly flexible ankle and foot can cause excessive pronation, a too-rigid ankle will cause the effects of caves foot. Although the arch of the foot itself may be normal, it appears very high because the foot doesn’t flatten inwards when weight is placed on it. Such feet are poor shock absorbers and increase the risk of fractures higher in the legs.
Bowlegs or knock knees add extra stress through knees and ankles over time, and may make ankle sprains more likely.

Other structural conditions that make sports injuries more common include:

  • lumbar lordosis: forward curve in the lower spine
  • patella alta: a kneecap that’s higher than usual
  • high Q angle: kneecap displaced to one side, as with knock knees

Having some muscles that are very strong and others that are weak can lead to injury. If your quadriceps (front thigh muscles) are very strong, it can increase the risk of a stretched or torn hamstring (rear thigh muscle). Tight iliotibial bands may be the cause of knee pain for many athletes in running sports.

Overuse injuries are caused by repeated, microscopic injuries to a part of the body. Many long distance runners experience overuse injuries even after years of running. For road runners, the surface is hard and sometimes uneven, and the running movements are repetitive. In addition, there are usually both up- and downhill elements, and these increase the stress on tendons and muscles in the lower leg. You will more likely develop running injuries if you wear the wrong shoes or sneakers. You should use footwear that doesn’t allow side-to-side movement of the heel, and that adequately cushions the foot.

People who play request sports tend to injure their upper body. The need to firmly grasp the request and the shock of impact with the ball can cause various injuries to the tendons of the wrist and elbow, such as “tennis elbow,” which may extend into the muscles of the forearm. In addition, the human arm really isn’t designed to handle strenuous activity above the head. Tennis is a leading cause of rotator cuff (shoulder joint) tendinitis. This is potentially one of the most difficult sports injuries. If you continue to play tennis when you have a sore shoulder, the rotator cuff tendons can fray or tear and may require surgery.

Question.11. Mention any four points to show the importance of yoga. **
Answer.
A foundation for healthy living. By closely observing the lifestyles and needs of people in the west Swami Vishnudevananda synthesized the ancient wisdom of yoga into five basic principles that can easily be incorporated into one’s lifestyle and provide a solid foundation for healthy living. It is around these four principles that the teachings are based.

  1. Proper Exercise (Asana)
  2. Proper Breathing (Pranayama)
  3. Proper Relaxation (Savasana)
  4. Proper Diet (Vegetarian)

Proper Exercise (Asana)
Acts as a lubricating routine for the joints and muscles and other parts of the body by increasing circulation and flexibility. The asanas not only produce physical benefits, but are also mental exercises in concentration and meditation, promoting optimum health. Our physical body is meant to move and exercise. If our lifestyle does not provide natural motion of muscles and joints, then disease and great discomfort will ensue with time. Proper exercise should be pleasant to the practitioner while beneficial to the body, mind and spiritual life.
There are numerous modern physical culture systems designed to develop the muscles through mechanical movements and exercises. As Yoga regards the body as a vehicle for the soul on its journey towards perfection, Yogic physical exercises are designed to develop not only the body. They also broaden the mental faculties and the spiritual capacities.
The Yogic physical exercises are called Asanas, a term which means steady pose. This is because the Yoga Asana (or posture) is meant to be held for some time. However this is quite an advanced practice. Initially, our concern is simply to increase body flexibility.
The body is as young as it is flexible. Yoga exercises focus on the health of the spine, its strength and flexibility. The spinal column houses the all-important nervous system, the telegraphic system of the body. By maintaining the spine’s flexibility and strength through exercise, circulation is increased and the nerves are ensured their supply of nutrients and oxygen.The Asanas also affect the internal organs and the endocrine system (glands and hormones)

Proper Breathing (Pranayama)
Connects the body to the solar plexus, where tremendous potential energy is stored. Through specific breathing techniques this energy is released for physical and mental rejuvenation. By far the most important thing about good breathing is the Prana, or subtle energy of the vital breath. Control of the Prana leads to control of the mind. Breathing exercises are called Pranayamas, which means to control the Prana.The two main Pranayamas practiced are Kapalabhati and Anuloma Viloma

Proper Relaxation (Savasana)
Yoga teaches three levels of relaxation – physical, mental and spiritual.
Long before the invention of cars, planes, telephones, computers, freeways and other modern triggers of stress, the Rishis (sages or seers) and Yogis of yore devised very powerful techniques of deep relaxation. As a matter of fact, many modern stress-management and relaxation methods borrow heavily from this tradition. By relaxing deeply all the muscles the Yogi can thoroughly rejuvenate his nervous system and attain a deep sense of inner peace.When the body and the mind are constantly overworked, their natural efficiency to perform work diminishes. Modern social life, food, work and even the so-called entertainment, such as disco dancing, make it difficult for modern people to relax. Many have even forgotten that rest and relaxation are nature’s way of recharging. Even while trying to rest, the average person expends a lot of physical and mental energy through tension. Much of the body’s energy is wasted uselessly.More of our energy is spent in keeping the muscles in continual readiness for work than in the actual useful work done. In order to regulate and balance the work of the body and mind, it is best to learn to economize the energy produced by our body. This may be done by learning to relax.It may be remembered that in the course of one day, our body usually produce all the substances and energy necessary for the next day. But it often happens that all these substances and energy may be consumed within a few minutes by bad moods, anger, injury or intense irritation. The process of eruption and repression of violent emotions often grows into a regular habit. The result is disastrous, not only for the body, but also for the mind.During complete relaxation, there is practically no energy or “Prana” being consumed, althouth a little is keeping the body in normal condition while the remaining portion is being stored and conserved.In order to achieve perfect relaxation, three methods are used by yogis: “Physical”, “Mental”, and “Spiritual” relaxation. Relaxation is not complete until the person reaches that stage of spiritual relaxation, which only advanced spiritual aspirants know.

Proper Diet (Vegetarian) is eating with conscious awareness. A yogi takes food which has the most positive effect on the body and mind and the least negative effect on the environment. Besides being responsible for building our physical body, the foods we eat profoundly affect our mind. For maximum body-mind efficiency and complete spiritual awareness, Yoga advocates a lacto-vegetarian diet. This is an integral part of the Yogic lifestyle.
The yogic diet is a vegetarian one, consisting of pure, simple, natural foods which are easily digested and promote health. Simple meals aid the digestion and assimilation of foods. Nutritional requirements fall under five categories: protein, carbohydrates, minerals, fats and vitamins. One should have a certain knowledge of dietetics in order to balance the diet. Eating foods first-hand from nature, grown in fertile soil (preferably organic, free from chemicals and pesticides) will help ensure a better supply of these nutritional needs. Processing, refining and overcooking destroy much food value.
There is a cycle in nature known as the “food cycle” or “food chain”. The Sun is the source of energy for all life on our planet; it nourishes the plants (the top of the food chain) which are then eaten by animals (vegetarian), which are then eaten by other animals (carnivores). The food at the top of the food chain, being directly nourished by the Sun, has the greatest life promoting properties. The food value of animal flesh is termed as “second-hand” source of nutrition, and is inferior in nature. All natural foods (fruits, vegetables, seeds, nuts and grains) have, in varying quantities, different proportions of these essential nutrients. As source of protein, these are easily assimilated by the body. However, second-hand sources are often more difficult to digest and are of less value to the body’s metabolism. Many people worry about whether they are getting enough protein, but neglect other factors. The quality of the protein is more important than the quantity alone. Dairy products, legumes, nuts and seeds provide the vegetarian with an adequate supply of protein. The high protein requirement still being used by many Health Departments is based on antiquated data and has been scientifically disproved many times in the laboratory. A healthy motto is: “Eat to live, not live to eat”. It is best if we understand that the purpose of eating is to supply our being with the lifeforce,or Prana, the vital life energy. So the greatest nutritional plan for the Yoga student is the simple diet of natural fresh foods.
However, the true Yogic diet is actually even more selective than this. The Yogi is concerned with the subtle effect that food has on his mind and astral body. He therefore avoids foods which are overly stimulating, preferring those which render the mind calm and the intellect sharp. One who seriously takes to the path of Yoga would avoid ingesting meats, fish, eggs, onions, garlic, coffee, tea (except herbal), alcohol and drugs.
Any change in diet should be made gradually. Start by substituting larger portions of vegetables, grains, seeds and nuts until finally all flesh products have been completely eliminated from the diet.The Yogic diet will help you attain a high standard of health, keen intellect and serenity of mind.

Question.12. Explain any two methods for flexibility development.
Answer:

  1.  Warm-up before stretching: The very first thing you must do before stretching is a warm up jog, run, or bike to get loose. You don’t have to run or bike that hard Or far, but it is good to do at least 20 minutes of warm up before stretching.
  2.  Do dynamic stretching : Dynamic stretching includes motion and is meant to mimic and exaggerate the movements of actual exercise and daily motions.

Question.13. Explain ethics in sports. **
Answer.
To understand the role ethics plays in sport and competition, it is important to make a distinction between gamesmanship and sportsmanship.
Gamesmanship is built on the principle that winning is everything. Athletes and coaches are encouraged to bend the rules wherever possible in order to gain a competitive advantage over an opponent, and to pay less attention to the safety and welfare of the competition. Some of the key tenants of gamesmanship are:
Winning is everything
It’s only cheating if you get caught
It is the referee’s job to catch wrongdoing, and the athletes and coaches have no inherent responsibility to follow the rules
The ends always justify the means
Some examples of gamesmanship are:
Faking a foul or injury
Attempting to get a head start in a race
Tampering with equipment, such as corking a baseball bat in order to hit the ball farther
Covert personal fouls, such as grabbing a player underwater during a water polo match
Inflicting pain on an opponent with the intention of knocking him or her out of the game, like the Saint’s bounty scandal
The use of performance-enhancing drugs
Taunting or intimidating an opponent
A coach lying about an athlete’s grades in order to keep him or her eligible to play
All of these examples place greater emphasis on the outcome of the game than on the manner in which it is played.
A more ethical approach to athletics is sportsmanship. Under a sportsmanship model, healthy competition is seen as a means of cultivating personal honor, virtue, and character. It contributes to a community of respect and trust between competitors and in society. The goal in sportsmanship is not simply to win, but to pursue victory with honor by giving one’s best effort.
Ethics in sport requires four key virtues: fairness, integrity, responsibility, and respect.
Fairness:
All athletes and coaches must follow established rules and guidelines of their respective sport.
Teams that seek an unfair competitive advantage over their opponent create an uneven playing field which violates the integrity of the sport.
Athletes and coaches are not discriminated against or excluded from participating in a sport based on their race, gender, or sexual orientation.
Referees must apply the rules equally to both teams and cannot show bias or personal interest in the outcome.
Integrity:
Similar to fairness, in that any athlete who seeks to gain an advantage over his or her opponent by means of a skill that the game itself was not designed to test demonstrates a lack of personal integrity and violates the integrity of the game. For example, when a player fakes being injured or fouled in soccer, he or she is not acting in a sportsmanlike manner because the game of soccer is not designed to measure an athlete’s ability to flop. Faking is a way of intentionally deceiving an official into making a bad call, which only hurts the credibility of the officiating and ultimately undermines the integrity of the game.
Responsibility:
To be sportsmanlike requires players and coaches to take responsibility for their performance, as well as their actions on the field. This includes their emotions.
Many times athletes and coaches will make excuses as to why they lost the game. The most popular excuse is to blame the officiating. The honorable thing to do instead is to focus only on the aspects of the game that you can control, i.e. your performance, and to question yourself about where you could have done better.
Responsibility requires that players and coaches be up to date on the rules and regulations governing their sport.
Responsibility demands that players and coaches conduct themselves in an honorable way off the field, as well  as on it.
Respect:
All athletes should show respect for team mates, opponents, coaches, and officials.
All coaches should show respect for their players, opponents, and officials.
All fans, especially parents, should show respect for other fans, as well as both teams and officials.
The sportsmanship model is built on the idea that sport both demonstrates and encourages character development, which then influences the moral character of the broader community. How we each compete in sports can have an effect on our personal moral and ethical behaviour outside of the competition.

Some argue for a “bracketed morality” within sports. This approach holds that sport and competition are set apart from real life, and occupy a realm where ethics and moral codes do not apply. Instead, some argue, sports serves as an outlet for our primal aggression and a selfish need for recognition and respect gained through the conquering of an opponent. In this view, aggression and victory are the only virtues. For example, a football player may be described as mean and nasty on the field, but kind and gentle in everyday life. His violent disposition on the field is not wrong because when he is playing the game he is part of an amoral reality that is dictated only by the principle of winning.

An ethical approach to sport rejects this bracketed morality and honors the game and one’s opponent through tough but fair play. This means understanding the rules and their importance in encouraging respect for your opponent, which pushes you to be your best.

Question.14. “Games and sports are the best means for attaining fitness.” Justify. **
Answer. It is known that fitness and wellness makes an individual physically fit,mentally stable and helps becoming a good citizen. Fitness helps individual achieve satisfactory level of strength, endurance and flexibility. It further improves the confidence and energy level. One feels more energetic and fresh for the whole day.

  2. One can take-up the fitness program at any age.
  3. Fitness program must be scientifically chalked out depending on age,sex and ability.
  4. Programme must be simple to complex.

Question.15. Elucidate the role of media for improvement of positive sports environment.
Answer : The media, whether it is print media or electronic media, plays a significant and effective role for creating positive sport environment. Media is providing its valuable contribution for the encouragement and promotion of sports and games. Electronic media is the source by which millions of people watch the various World cups and Olympic games. There are many sports channels are available such as Ten sports, NEO sports, Star sports that provide the facility of watching live and recorded programs of games and sports. Thus media is promoting the games and sports.
The media encourages people to develop reasonable interests in engaging in sports. Either for fun, excitement, recreation, physical fitness or health care. In the homes, countless number of youths involves themselves in sporting activities. This has contributed to the remarkable improvement of fitness among the youths. Another role that the media play in sports is the advocacy of unity among diverse races, religions, ethinic groups, language, colour, peoples, idiosyncrasies and world¬views. Media not only publicise the games and sports but it also gives publicity to sportspersons which is a motivating source for them.

Question.16. Explain any three techniques of meditation. **
Answer. 1. BUDDHIST MEDITATION
Zen Meditation (Zazen)
Zazen means “seated Zen”, or “seated meditation”, in Japanese. It has its roots in the Chinese Zen Buddhism (Ch’an) tradition, tracing back to Indian monk Bodhidharma (6th century CE). In the West, its most popular forms comes from Dogen Zenji (1200~1253), the founder of Soto Zen movement in Japan. Similar modalities are practiced in the Rinzai school of Zen, in Japan and Korea.

2.HINDU MEDITATION (Vedic & Yogic)
Mantra Meditation (OM Meditation)
A mantra is a syllable or word, usually without any particular meaning, that is repeated for the purpose of focusing your mind. It is not an affirmation used to convince yourself of something.
Some meditation teachers insist that both the choice of word, and its correct pronunciation, is very important, due to the “vibration” associated to the sound and meaning, and that for this reason an initiation into it is essential. Others say that the mantra itself is only a tool to focus the mind, and the chosen word is completely irrelevant.
Mantras are used in Hindu traditions, Buddhist traditions (especially Tibetan and “Pure Land” Buddhism), as well as in Jainism, Sikhism and Daoism (Taoism). Some people call mantra meditation “om meditation”, but that is just one of the mantras that can be used. A more devotion oriented practice of mantras is called japa, and consists of repeating sacred sounds (name of God) with love.

3.CHINESE MEDITATION
Daoism is a Chinese philosophy and religion, dating back to Lao Tzu (or Laozi). It emphasizes living in harmony with Nature, or Tao, and it’s main text is the Tao Te Ching, dating back to 6th century B.C. Later on some lineages of Taoism were also influenced by Buddhist meditation practices brought from India, especially on the 8th century C.E..
The chief characteristic of this type of meditation is the generation, transformation, and circulation of inner energy. The purpose is to quieten the body and mind, unify body and spirit, find inner peace, and harmonize with the Tao. Some styles of Taoist Meditation are specifically focused on improving health and giving longevity.

Question.17. Explain any three principles of training in brief.
Answer: Three principles of training:

  1.  Principle of overload : The overload principle is a basic sports fitness training concept. It means that in order to improve, athletes must continually work harder as they their bodies adjust to existing workouts. Overloading also plays a role in skill learning.
  2. Principle of Specificity : The principle of specificity states that the more specific a training activity is to a given sport—muscle group, work load, velocity and pattern of movement, body posture, and range of motion—the more it will contribute to increasing performance in that sport. .
  3. Principle of Individualization : This could also be called the snowflake principle, since it highlights that no two climbers—or their optimal conditioning program-are the same. The best training program for a person will target his/ her specific weaknesses, address past or present injuries, provide sufficient time for recovery, and be structured to provide the greatest output for the available training input.

Question.18. Suggest the formation of various committees for systematic and smooth conduct of sports day in your school.
Answer :

  1. Select members who are excited about the project : If you’ve been working with the same committee for years, they may be growing bored or frustrated with the annual undertaking.
  2.  Clearly define tasks : Progress on your event will come to a halt if your committee members don’t know what to do next. At the end of each planning session, members should know their next steps and the deadlines for completing each task.
  3.  Plan ahead : Send committee members the meeting schedule several weeks in advance so they can clear the time to attend meetings.
  4.  Establish goals and expectations : When someone joins your committee, communicate clearly how much time they should set aside to complete their tasks.

Question.19. Explain in detail about any five advantages of correct posture.
Answer: Posture is the position you maintain while standing, sitting or lying down. You have good posture when your position creates the least amount of strain on supporting muscles and ligaments when you move or perform weight-bearing activity. It has many advantages. Some of them are :

  1.  Better for Your Body : Good posture and back support are essential for avoiding back and neck pain. Good posture also prevents muscle aches and muscle fatigue. It keeps your bones and joints in proper alignment so you use your muscles more efficiendy, preventing strain and overuse.
  2. Future Health : Proper posture reduces abnormal wear and tear on joint surfaces, which can lead to arthritis. It also reduces stress on ligaments that connect spinal joints. Good posture helps you avoid developing an abnormal permanent position, which can cause spinal disk problems and constricted blood vessels and nerves. Good posture also protects spinal joints from injury and deformity.
  3. Breathe Right: Good posture helps to open the airways and ensure proper breathing. Proper breathing allows enhanc-ed oxygen flow in the cardiopulmonary system. The blood then carries sufficient oxygen to the nervous system, organs and other tissues, so they function effectively.
  4. Looking Good : Maintaining good posture does wonders * for your appearance. Proper posture can help you make a good
    first impression, and appear more attractive and-confident.
  5.  Good posture : Good posture prevents fatigue because muscles are being used more efficiently, allowing the body to use less energy.

Question.20. What is the role of various elements of diet on performance
of an athlete?
Answer: Eating a balanced diet means choosing a wide variety of foods and drinks from all the food groups. It also means eating certain things in moderation, namely saturated fat, trans fat, cholesterol, refined sugar, salt and alcohol. The goal is to take in nutrients you need for health at the recommended levels.

  1. Most of the energy used by the body is provided by the carbohydrate and the fats.
  2. Proteins build the body and perform the function of repair of damage tissues.
  3. Minerals an’d vitamins regulate the functions of the body; they are needed for important chemical reactions taking place in the body.
  4. Water is present in all tissues of the body and plays an important role in various life processes. For example, digestion, excretion and transport of important materials within the body. It also helps in cellular reactions.

Question.21. What is endurance? Explain the various methods for its development.
Answer : Endurance refers to the body’s ability to continue using muscular strength and endure repeated contractions for an extended period of time. It is essential in exercise and when doing heavy tasks as it allows the muscles to perform for long periods of time without becoming tired. There are various methods of its development. Some are as follows :

  1.  Continuous Training : Continuous training is a type of sports training that involves activity of moderate intensity with a duration of-more 15 minutes with resting intervals. It is the most common type of training and is for maintaining general health and well being. Generally, this type of training is used to prepare the body for sustained workouts such as marathons and triathlons, but can also be effective for more casual athletes. It allows the body to work from its aerobic energy stores to improve overall fitness and endurance. Chief
    -benefits of continuous training include fat burning, muscle building, and increasing maximum aerobic potential.
  2.  Interval training: Interval training involves periods of hard work followed by a timed period of rest, repeated several times in one training session. The periods of hard work are called high intensity activity. Rest can be active (walking, jogging etc) An example of interval training is 10 fast runs over 40 metres, with a two minute rest between each run. Variables to consider during interval training are Distance/duration of activity, Intensity of activity, duration of rest, activity during rest, number of sets, and frequency of training. By varying any of the variables athletes can be progressively overloaded. This form of training also increases fitness levels for people involved in exercise.
  3. Fartlek training : Fartlek, which means “speed play” in Swedish, is a training method that blends continuous’ training with interval training. The variable intensity and continuous nature of the exercise. places stress on both the aerobic and anaerobic systems. It differs from traditional interval training in that it is unstructured; intensity and/or speed vary, as the athlete wishes. Fartlek training can be used to improve both the aerobic and anaerobic systems by mixing moderate activity with bursts of speed.

Though The BJP and the Left Front did not join the government they gave support from the outside. The Coalition Era had many Prime Ministers and some of them held office for short durations. Some of them were

The coalition era saw that no single party could enjoy majority on its own as in the past decades and also the strengthening of Regional Parties.
Rise and fall of two coalition governments :

  1.  The first coalition government in the late 1980s was formed by the National Front under the leadership of V.P. Singh.
    Both The BJP and Left Front supported V.P. Singh because they wanted to keep the Congress out of power. The Mandal Commision Report and implementation of its recommendations forced The BJP to reconsider its support and finally withdraw it. Thus in November 1990, the rule of National Front came to an end.
  2. BJP came to power for the first time in May 1996 as a minority government but it was for just a month. In June 1996, The BJP failed to get majority support in the vote of confidence and thus had to quit.

Question.21. Explain the ‘Cuban Missile Crisis’.
Answer.

  1. Cuba was an ally of the Soviet Union, received both displomatic and financial aid from it. In 1961, the leaders of the then USSR were worried that USA might invade Cuba and overthrow President Fidel Castro. During such a situation, the leader of the Soviet Union, Nikita Khrushchev decided to convert Cuba into a Russian base. In 1962, he had set up nuclear missiles in Cuba. These missiles could be at close range to the US and even reach upto Canada.
  2.  Americans became aware only after three weeks that the Soviet Union had placed nuclear weapons in Cuba. Kennedy ordered American warships to stop and check any Soviet ship moving towards Cuba as a way of warning to the USSR.
  3.  It was also feared that Cuba might have learnt the technology behind nuclear weapons that would be anytime danger to the US prosperity.
  4.  The Cuban crisis also led US to suspect all Soviet-aided countries and forced it to set up military blocs in different parts of the world as NATO, SEATO and CENTO.

Question.22. Describe any two major constraints of the U.S. hegemony.
Answer. Institutional Architecture: The very first constraint lies in the institutional architecture of the American state. A system ofdivision of powers between the three branches of government places significant brakes upon the unrestrained and immoderate exercise of America’s military power by the executive branch.
Open nature of American society possesses constraint: The second constraint on American hegemony is also domestic in nature and stems from the open nature of American society. In spite of mass media’s promotion or imposition of a particular perspective on domestic opinion in the US, there is nevertheless a deep scepticism regarding the purposes and methods of government in American political culture.

Question.23. Name one country each from the continents of America, Africa, Asia and Europe, wherein the UN ‘Peacekeeping Operations’ were administered.
Answer. Countries were the UN Peacekeeping Operations were admfnstered.

  1.  America – Haiti-2004
  2.  Africa – Ethiopia and Eritrea-2000
  3.  Asia -India and Pakistan-1949
  4.  Europe – Georgia-1993

Question.24. How is global poverty a source of insecurity ? Explain.
Answer. ‘Global Poverty’ is one of the important sources of insecurity which threatened the entire development of global era. It refers to a situation in which a poor country suffers from
(i) slow economic growth(ii) low national income (iii) low standard of living and (iv) less calories
intake among the people with high population growth.
According to the recent data, half the world’s population growth occurs in most of the developing countries like India, Pakistan, Nigeria, Bangladesh and Indonesia. Among the world’s poorest countries, population is expected to treble in the next 50 years. Hence low incomes and high population growth reinforce each other to make poor states and poor groups get poorer.
Implications
Globally, this poverty creates disparity between the northern and southern countries of the world.
Poverty in the South has also led to a large-scale migration to seek a better life (especially better economic opportunities) in the North.
All this created international political frictions, as International law and norms make a distinction between migrants and refugees. In this regard states are generally supposed to accept refugees, but they do not have to accept migrants.

Question.25. ‘Let the polluters pay’. Support this statement with any two suitable arguments.
Answer. “Let the polluters pay” is the statement quoted by the developing countries of south to the developed countries of north at the negotiations between south and north countries over environmental pollution.
It is very significant that compromise and accommodation are the two essential policies required by states to save planet Earth. But there is a difference in the approach to environment between the countries of the North and the South. We can throw light on the ongoing negotiations between the North and south on environmental issues in such a manner:
The developed countries of the north want to discuss the environment issue as it stands now and want everyone to be equally responsible for ecological conservation.
At the same time the developing countries of the south feel that much of the ecological degradation in the world is the product of industrial development undertaken by the developed countries.
And if developed countries have caused more degradation they must also take- more responsibility for ongoing damage now.
On the other side the developing countries are in the process of industrialization and they must not be subjected to the same restrictions which apply to the developed countries.
However, the special needs of the developing countries must be taken into account in the development, application and interpretation of rules of International Environmental Law. And this argument was accepted in the Rio Declaration at the “Earth Summit in 1992 under the principle of common but differentiated responsibility.

Question.26. “Globalisation has shifted power from nation-states to global consumers.” Justify the statement.
Answer. Globalisation has shifted power from nation-state to global consumers. This can be justified in the context of which globalisation has reduced the state capacity to govern.
To some extent under its arena globalisation affects traditional concept of state sovereignty. It also results in an erosion of state capacity, that is, the ability of government to do what they do.

  1.  All over the world, the old welfare state is now giving way to a more minimalist state that performs certain core functions i.e., the maintenance of law and order.
  2.  However it withdraws from many of its earlier welfare functions directed at economic and social well being.
  3.  In place of the welfare state, it is the market that becomes the prime determinant of economic and social priorities.

Thus, the entry and the increased role of MNCs all over the world leads to a reduction in the capacity of government to take decisions on its own.
Positive Impacts of Globalisation are as follows :

  1. Helps in development and strengthening of domestic economies of developing countries.
  2. Improved productive efficiency and healthy competition.
  3.  New cultural values are moving towards old traditions and customs

Question.28. Explain any two features of Indian nuclear policy.
Answer. India’s Nuclear policy advocates ‘no first use’ and reiterates India’s commitment to global
verification on non-discriminatory nuclear disarmament leading to a nuclear weapons free world.

  1.  The nuclear programme in India was initiated in the late 1940s under the guidance of H.J. Bhabha.
  2. When China conducted a nuclear test in 1964, India realised its strategic importance.
  3.  India’s first nuclear experiment was conducted in 1974. India declared that it was only for peaceful purposes.
  4. At the same time India refused to sign the CTBT in 1995 because of its discriminatory nature.
  5.  Later on, India also conducted a series of nuclear tests in May 1998, demonstrating its capacity to use nuclear energy for military purposes.

Question.29. “1960s were labelled as the ‘dangerous decade’ Explain with the help of any four arguments.
Answer. The 1960s was labelled as the ‘dangerous decade’ because of some unresolved problems like poverty, inequality and communal and regional divisions.
There was speculation that all these could lead to a failure of the democratic project or even the disintegration of the country.

  1.  Economic Crisis— Due to the India-China and Indo-Pak war there was economic crisis in India. So the government of Indira Gandhi decided to devalue the Indian rupee to check economic crisis. Consequently, the economic situation triggered a price rise.
  2.  Political Earthquake— The election of 1967 was termed as the Political Earthquake because it jolted the Congress both at the national and state levels. Half the ministers in Indira Gandhi’s cabinet were defeated.
  3.  Food Crisis— Besides, due to failure of monsoons, drought occurred and this created a serious food crisis in India during 1960s.
    Hence, there was speculation that all these challenges could lead to failure of the democratic project or even the disintegration of the country.

Question.30. What was the main outcome of the Rajiv Gandhi – Longowal Accord in July 1985 ?
Answer. The Punjab Accord was an agreement signed between the then Prime Minister Rajiv Gandhi and Harchand Singh Longowal, the then President of the Akali Dal in 1985.
This agreement is known as the “Rajiv Gandhi-Longowal Accord” or the Punjab Accord. It was a step towards bringing normalcy in Punjab.
Main provisions of the Accord :

  1.  Under this accord, it was agreed that Chandigarh would be transferred to Punjab.
  2.  A separate commission would be appointed to resolve the border dispute between Punjab and Haryana.
  3.  A tribunal would be set up to decide the sharing of Ravi-Beas river water among Punjab, Haryana and Rajsathan.
  4. The agreement also provided for compensation to and better treatment of those affected by militancy in Punjab and the withdrawal of the application of Armed Forces Special Powers Act in Punjab.

However, peace did not come easily or immediately. The cycle of violence continued nearly for a decade.
(a) Militancy and counter insurgency violence led to excesses by the police and violation of the human rights.
(b) Politically it led to fragmentation of the Akali Dal.
(c) Thus, the central government had to impose President’s rule in the state and the normal electoral and political process was suspended.
(d) It was not easy to restore the political process in the atmosphere of suspicion and violence. For example when elections were held in Punjab in 1992, only 24 per cent of the electors turned out to vote.
All these in turn added to tension between Punjab and its neighbouring states.

Question.31. What is the relevance of the Non-aligned Movement after the end of Cold War ? Explain.
Or
Analyse Indian’s changing relationship with post-communist Russia
Answer. Non-alignment as a strategy evolved in the Cold War context, but the end of “Cold War” and a unipolar world did not see the end of the non-alignment.
Non-alignment still contains some core values and end-using ideas.
• Its emphasis has shifted from “political issues to economic issues”.
• Liberalisation of third world economies for rapid development of the countries of south now remains the main concern of NAM.
• Issues like democracy, disarmament, human rights and neo-colonialism are as relevant today as earlier.
With the disintegration of the erstwhile USSR, there is only one super power therefore, it is very essential for NAM to make sincere efforts to check USA from taking unilateral decisions.
• Now its emphasis has also shifted towards poverty alleviation, New International Economic Order based on equality, equity and justice and promotion of industrialisation.
NAM must make efforts to reshape and democratise the United Nations so that the domination of powerful countries is checked.
Besides, NAM must ensure that in the era of Globalisation, liberalism and explosion of Information Technology (IT), the developed and developing nations derive the maximum benefit and are not allowed to be exploited.
Therefore, the concept of non-alignment is applicable even in normal situation. Its essence is that every international issue is discussed on merit. This is an attitude which must be reflected in international affairs.
Or
India should maintain a healthy relation ship with Russia because, Indo-Russian relations are embedded in a history of tru^t and common interests and are matched by popular perceptions.
• Common view on the multipolar world order : Russia and India share a vision of multipolar world order. For both these countries multipolar world order is the co-existence of several powers in the international system, collective security, greater regionalism, negotiated settlements of international conflicts an independent foreign policy for all countries and decision making through bodies like the UN that should be strengthened, democratised and empowered.
• India’s stand towards Russia : India gets meaningful benefits for having healthy relations with Russia on the issues like Kashmir, energy supplies, sharing information on international terrorism, access to central Asia, and balancing its relation with China.
• Russia’s stand towards India: Like India Russia stands to benefit from this relationship because India is the second largest arms market for Russia.
Besides, Indian military gets most of its hardware from Russia. Since India is an oil importing nation, so Russia is important to India and has repeatedly come to the assistance of India during its oil crisis.
In order to meet the demands of energy India is trying to increase it energy imports from Russia and the republics of Kazakihstan and Turkimenistan. This also broadened the scope for partnership and investment in oilfields.
India has also strengthened its relation with Russia for her nuclear energy plans and space industry. India gets the cryogenic rocket from Russia whenever it needed it.
Thus, we may safely conclude that India has maintained good relations with all the post¬communist countries. But the strongest relations are still those between Russia and India.

Question.32. Why is the European Union considered a highly influential regional organisation in the economic, political and military fields ?
Or
No region exists in a vacuum. It is influenced by outside powers and events no matter how much it may try to insulate itself from non-regional powers. China and the United States remain key players in South Asian politics. Sino-Indian relations have improved significantly in the last ten years, but Cina’s strategic partnership with Pakistan remains a major irritant. The demands of development ana globalisation have brought the two Asian giants closer, and their economic ties have multiplied rapidly since 1991.
Study the paragraph given above carefully and answer the following questions :
(i) Which two countries have been referred to as ‘outside powers’ ?
(ii) Which are the two Asian giants and why have they been called so ?
(iii) China’s strategic partnership with Pakistan is a major irritant for which country and why ?
Answer. As a supranational organisation, the European Union intervenes in economic, political and social areas. It has thus, economic, political diplomatic and military influence.
As far as the economic nature/aspect of European Union is concerned, it is considered as the World’s biggest economy with a GDP of more than $12 trillion in 2005, slightly larger than that of the united states.
(a) European Union’s economic power gives it influence over its closest neighbours as well as in Asia and Africa.
(b) Its share of world trade is three times larger than that of the United States.
(c) Its uniform currency, the euro, can pose a threat to the dominance of the US dollar.
(d) Moreover, European Union also functions as an important bloc in international organisations such as the World Trade Organisation (WTO).
In this way, as a supranational organisation, the European Union is able to intervene in Economic Areas.
Besides being the world’s biggest economy European Union also has political and diplomatic influence in the world arena. Political and Diplomatic Aspects.
The European Union has a great influence on some of the UN policies because its two members, Britain and France, hold permanent seats in the UN security Council. It also includes several non-permanent members of the UNSC.
Not only this, European Union has its very effective influence in the arenas of diplomacy, economic investments and negotiations except coercion and military force. For example European Union’s dialogue with China on human rights and environmental degradation seemed to be very effective.
“European Union” was established in 1992 after the collapse of the Soviet Union. The European
Union was started as an Economic Union but over time it has evolved from Economic Union
to increasingly political one. „ .
Hence, the EU now has started to act more as a nation-state.
(a) It has tried to expand areas of cooperation while acquiring new members, especially from the erstwhile soviet bloc.
(b) Besides, European Union has its own flag, anthem, founding date and currency.
(c) It has also some form of a common foreign and security policy in its dealings with other nations.
Or
(i) China and United States have been refered to as “outside powers”.
(ii) China and India are the two Asian giants.
They are called so because of their population ratio and fastest economic growth in the world.
(iii) China’s strategic partnership with Pakistan is a major irretant for India because of Pakistan’s anti-Indian outlook.

Question.33. How was ‘one party dominance’ in India different from the ‘one party system’ of Mexico ? In your opinion, which of the two political systems is better and why ?
Or
Explain the main arguments in the debate that ensued between industrialisation and
agricultural development at the time of Second Five Year Plan.
Answer. Main differences between Mexico and India under one party domination were as follows:

  1.  Mexico one party domination i.e. the domination of Institutional Revolutionary Party was based on the “Perfect dictatorship” whereas, in India the Congress Party’s domination was based on “popular consensus”.
  2. In Mexico the elections were often rigged and manipulated by the ruling party i.e. PRI but in India elections were based on competition among political parties.
    (a) ‘One party dominant systems’ means that a single party enjoys monopoly of power over a long period of time and exclusion of other parties to reach the power.
    (b) No. The dominance of one party did not mean that India was really not a democracy. Even though Congress had domihahce Era, the Indian political system is still democratic for the following reasons:
    (i) Open nature of the Indian political system, i.e., existence of multi-party system.
    (ii) At the time of independence, there was no strong political party except the Congress.
    (iii) The role of Congress during our freedom struggle could be remembered and people cast votes as their tribute to the Congress leaders.
    (iv) The regional parties gained importance at national levels and multi-party system had come into the picture since 1989.
    (v) The advancement in the electoral system (electronic voting machine, common platform for political agenda) strengthened the democratic pattern.
    (vi) Active participation of women and improvement in Panchayat Raj system and its success express Indian political system as democratic.

Or
The strategy of development followed after independence raised some key controversies regarding the relevance of agriculture over industry at the time of Second Five Year Plan.

  1.  At the time of the commencement of Second Five Year Plan many thought that the second plan lacked an agrarian strategy for development and emphasis on industry caused agriculture and rural India to suffer.
  2.  J.C. Kumarappa, a Gandhian Economist, proposed an alternative blueprint that put greater emphasis on rural industrialisation.
  3.  Chaudhary Charan Singh, the Bharatiya Lok Dal leader, said that planning was leading to the creation of prosperity in urban and industrial sections at the cost of rural welfare.

Whereas, others thought that without a drastic increase in industrial production there could be no escape from the cycle of poverty.

  1. They argued that Indian Planning did not have an agrarian strategy to boost the production of foodgrains.
  2.  It also proposed programmes of community development and spent large sums on irrigation projects. And the failure was not that of policy but of its non-implementation because of the politics of land owning classes.
  3.  They argued that even if the government had spent more money on agriculture it would not have solved the massive problem of rural poverty.

Question.34. What was Narmada Bachao Andolan ? What were its main issues ? What democratic strategy did it use to put forward its demands ? 
Or
In the midst of severe competition and many conflicts in 1989, a consensus appeared to have emerged among most parties. Explain any three points of consensus.
Answer. Narmada Bachao Andolan was a loose collective local organisation’s movement to save river Narmada. This movement opposed the construction of multi-purpose project known as the Narmada Sagar Project.

  1.  Since its inception the Narmada Bachao Andolan linked its opposition to the Sardar Sarovar Project with larger issues concerning the nature of ongoing developmental projects, efficacy of the model of development that the country followed and about what constituted public interest in a democracy.
  2. Thus, the movement demanded proper and just rehabilitation of all those who were directly or indirectly affected by the project.
  3. The NBA movement also questioned the nature of decision making processes that go in the making of mega scale development projects.
  4. The NBA also insisted that local communities must have a say in such decisions and that they should also have effective control over natural resources like water, land and forests.

Criticism against Narmada Bachao Andolan –

  1. Gujarat state government vigorously opposed the argument and agitation of the movement because state has been benefitted from the project. Besides,
  2.  The movement’s demand to stop the construction of the dam was severely criticised by many leaders and environmentalists on the grounds as :
    (a) The obstruction to the process of development
    (b) Denial to the access to water to many people and
    (c) Hurdle to economic development.
    Thus, the Narmada Bachao Andalan could not gain much support among the main stream political parties including the opposition parties.

Or
In the midst of severe competition and many conflicts, a consensus appears to have emerged among most parties or many crucial issues. This consensus consists of four elements.

  1. Agreement on new economic policies : While many groups are opposed to the new economic policies, most political parties believe that these policies would lead the country to prosperity and a status of economic power in the world.
  2. Acceptance of the political and social claims of the backward castes : Political parties have recognised that the social and political claims of the backward castes need to be accepted. As a result all political parties now support reservation of seats for the backward classes in education and employment. Political parties are also willing to ensure that the OBCs get adequate share of power.
  3. Acceptance of the role of state level parties in governance of the country: The distinction between state level and national level parties is fast becoming less important.
  4. Emphasis on pragmatic considerations rather than ideological positions and political alliances without ideological agreement : Coalition politics has shifted the focus of political parties from ideological differences to power sharing arrangements thus, most parties of the NDA did not agree with the Hindutva ideology of the BJP, yet, they came together to form a government and remained in power for a full term.
    All these are momentous changes are going to shape politics in the near future.

Question.35. Describe any three weaknesses and any three points of strength of India’s democracy that came to light during the Emergency of 1975.
Or
In the given political outline map of India, six states have been indicated by (A), (B), (C), (D),(E) and (F). Identify them with the help of the information given below and write their correct names in your answer book along with their respective Serial No. and the alphabet concerned as per the following table:
cbse-sample-papers-for-class-12-political-science-all-india-2012-4
cbse-sample-papers-for-class-12-political-science-all-india-2012-5
(i) Two states where the Congress party got majority and formed the government.
(ii) Two states where the breakaway Congress legislators played an important role in installing non-Congress governments.
(iii) A state where Congress parly did not get majority but formed the government with the help of other parties.
(iv) The state where’Popular United Front’came into power.
Answer. The emergency at once brought out both the weaknesses and the strengths of India’s democracy. Though there are many observers who think that India ceased to be democratic during the emergency. It is noteworthy that normal democratic functioning resumed within a short span of time. Hence, we learnt some lessons :
(i) The very first lesson we learnt is that it is extremely difficult to do away with democracy in India.
(ii) Secondly, it brought out some ambiguities regarding the emergency provision in the constitution that have been rectified since. Now, internal emergency can be proclaimed only on the grounds of “armed rebellion” and it is necessary that the advice to the president to proclaim emergency must be given in writing by the council of ministers.
(iii) The third lesson we learnt is that the emergency made every one more aware of the value of civil liberties.
The courts too have taken* an active role after the emergency in protecting the civil liberties of the individual. This is a response to the inability of the judiciary to protect civil liberties effectively during the emergency.
Critics view on emergency
(a) Critics of emergency point out that most of these promises by the government remained unfulfilled.
(b) They question the use of preventive detention on such a large scale.
(c) There were other and more serious allegations regarding the exercise of government power by people who held no official position, for example Sanjay Gandhi, the younger son of Prime Minister Mrs Indira Gandhi.
Not only this the emergency directly affected lives of common people in many cases like- torture and custodial deaths, arbitrary relocation of poor people and over-enthusiasm about population control led to cases of compulsory sterilisation.
These instances show what happens where the normal democratic process is suspended.

Question.5. Students of which two states started agitation against the rising food prices in 1974 ?
Answer. The students of Bihar and Gujarat started the agitation against the rising food prices in 1974.

Question.12. What is ‘cultural homogenisation’ ? Give an example to show that its consequence is not negative.
Answer. Cultural homogenisation is an aspect of globalisation which signifies uniform culture and common nature.
Cultural Aspect: As far as cultural consequences are concerned, it would be a mistake to assume that cultural consequences of globalisation are only .negative. Actually they are not a static thing. Sometimes external influences simply enlarge our choices and sometimes they modify our culture without overwhelming the traditional culture/norms. For example blue jeans can go well with hand-spun Khadi.
So, we can safely say that globalisation broadens our cultural outlook and promotes cultural homogenisation.

Question.25.What was the Tibet issue ? How did India help the Tibetan migrants to settle down ?
Answer.

  1. Tibet the Plateau of central Asian region is the one of the major issues that historically caused tension between India and China.
  2.  Very often China had claimed administrative control over Tibet and from time to time, Tibet was independent too. In 1950, China took control of Tibet. A large number of the Tibetans opposed this takeover. India tried to persuade China to recognise Tibet’s claim for Independence. Since then Tibet has become a major issue of conflict between India and China.
  3. Over the last half century a large number of Tibetans have sought refuge in India and many other countries of the world.
  4.  In Delhi, there are large settlements of Tibetan refugees. Dharamshala in Himachal Pardesh is perhaps the largest refuge settlement of Tibtans in India.
  5.  Dalai Lama, the religious leader of Tibetans in India, has also made Dharamshala his
    home in India.
  6.  Besides, in the 1950s and 1960s many political leaders and parities in India including the Socialist Party and the Jana Sangh supported the cause of Tibet’s independence.

Question.28.State four reasons as to why super-powers should have military alliances with small countries.
Answer.With their nuclear weapons and regular armies super powers were so powerful that the combined power of most of the smaller states in Asia and Africa and even in Europe, was no match to them. Yet, the smaller states were helpful to the superpowers in gaining access to:

  1.  Vital resources – such as soil and minerals.
  2.  Territory – from where the superpowers could launch their weapons and
    troops.
  3.  Locations – from where their superpowers could spy on each other.
  4.  Economic support – in that many small allies together could help pay for military
    expenses.
  5. Ideological reasons – They were also important for ideological reasons like the loyalty
    of allies suggested that the super powers were winning the war
    of ideas as well.

Question.29. Explain any two factors responsible for Pakistan’s failure in building a stable democracy.
Answer. (i) Social Dominance The social dominance of the military, clergy and land owning aristocracy has led to the frequent overthrow of elected governments and the establishment of military governments.
(ii) Conflict with India Pakistan’s conflict with India has made the paramilitary groups more powerful. These groups have often said that political parties and democracy in Pakistan are flawed that Pakistan’s security would be harmed by selfish- minded parties and chaotic democracy, hence, the army stay in power is justified.

Question.34. Why are India’s relations with Russia considered an important aspect of India’s foreign policy ? Explain.
Or
Explain the Eastern and the Western alliances during the Cold War period. Name any two European countries from amongst the following, which were not members of these alliances:
France, Poland, Sweden, Spain, Austria, Romania.
Answer. India’s relations with Russia are considered an important aspect of India’s foreign policy because Indo-Russian relations are embedded in a history of trust and common interests. Relations are also matched by popular perceptions.
Common view on the multipolar world order: Russia and India share a vision of multipolar world order. For both these countries a multipolar world order is the co-existence of several powers in the international system, collective security, greater regionalism, negotiated settlements of international conflicts an independent .foreign policy for all countries and decision making through bodies like the UN that should be strengthened, democratised and empowered.
• India’s stand towards Russia : India gets meaningful benefits for having healthy relations with Russia on the issues like Kashmir, energy supplies, sharing information on international terrorism, access to central Asia, and balancing its relation with China.
• Russia’s stand towards India : Like India Russia stands to benefit from this relationship because India is the second largest arms market for Russia.
• Besides, Indian military gets most of its hardware from Russia. Since India is an oil importing nation, so Russia is important to India and has repeatedly come to the assistance of India during its oil crisis.
• In order to meet the demands of energy India is trying to increase it energy imports from Russia and the republics of Kazakihstan and Turkmenistan. This also broadened the scope for partnership and investment in oilfields.
• India has also strengthened its relation with Russia for her nuclear energy plans and space industry. India gets the cryogenic rocket from Russia whenever it needed it.
• Thus, we may safely conclude that India has maintained good relations with all the post-communist countries. But the strongest relations are still those between Russia and India.
Or
The ‘Alliance system’ was developed by the two superpowers to expand their spheres of
influence in different parts of the world.
(i) In a world sharply divided between the two alliance systems, a state was supposed to remain tied to its protective superpower to limit the influence of the other super power and its allies.
(ii) The Alliance system led by the two super powers, therefore, threatened to divide the entire world into two camps (i) Western Alliances, (ii) Eastern Alliances.
The ideological reason of alliance system was winning the war of ideas like :

  1.  The western Alliance headed by the US, represented the ideology of liberal democracy and capitalism.-
  2. On the other hand Eastern alliance headed by the Soviet Union was committed to the ideology of socialism and communism.
  3. Sweden and Austria were not the members of these alliances of western bloc and eastern bloc.

1993 on the issue of demolition of Babri Masjid. –

Answer. Depletion of Natural Resources: Throughout the world cultivable area is barely expanding any more and a substantial portion of existing agricultural land is losing fertility; grasslands have been overgrazed and fisheries overharvested.
Loss of Biodiversity: Natural forests which help stabilise the climate, moderate water supplies and harbour a majority of the planet biodiversity on land are being cut down and people are being displaced. The loss of biodiversity continues due to the destruction of habitat in areas which are rich in species.

Question.22. How was the 1971 war forced upon India ? Explain in brief.
Answer. The struggle for the independence of Bangladesh started when West Pakistan did not allow the Awami League, a party of East Pakistan, to prove its majority and form the government. This enraged the East Pakistanis and they rebelled which was dealt with by an army crackdown. However, India had to intervene due to the atrocities committed by the Pakistani army on the unarmed people and due to influx of lakhs of refugees into India,
The government of India supported the demand of the people of East Pakistan for independence and helped them financially and militarily.
This resulted in a war between India and Pakistan in December 1971. The war ended with the surrender of the Pakistani forces in East Pakistan and the formation of Bangladesh as an independent country.

Question.25. Describe any four weaknesses of the Soviet System.
Answer. During the cold war era the Soviet system became very bureaucratic and authoritarian, making life difficult for its citizens. There were following reasons and situations which signify bureaucratic and authoritarian system of Soviet state like :
Lack of Democracy and absence of freedom : In the Soviet state there was “lack of democracy” and “the absence of freedom of speech” which stifled people who often expressed their dissent in jokes and cartoons.
Strict control over the institutions : Most of the institutions of the Soviet Union needed reform because the one party system-represented by the communist party of the soviet union had tight control over all institutions and was unaccountable to the people.
In this way, Soviet System became a bureaucratic and authoritarian state.
The Soviet system became weak and economy stagnant because the Soviet economy used, much of its resources in maintaining a nuclear and military arsenal and the development of its satellite states in Eastern Europe and within the Soviet system i.e. the five central Asian Republics in particular.
This practice led to a huge economic burden that the system could not cope up with.
At the same time ordinary citizens became more knowledgeable about the economic advancement of the west. They could see the disparities between their system and the systems of the west.
Thus, the reality of its backwardness came as a political and psychological shock to the people of Soviet state.

Question.26. Describe in brief the crisis China faced before ending political and economic isolation.
Answer. After the inception of the People’s Republic of China in 1949, China followed Soviet model of economy which allowed China to use its resources to establish the foundations of an Industrial economy. Since then China was completely isolated in politics and economic areas. But at same time in the following years, China faced various problems like;

  1. Economic growth was insufficient to meet the needs of a growing population.
  2.  Agricultural production was not sufficient to generate surplus for industary.
  3.  China’s Industrial production was not growing fast enough.
  4.  International Trade was minimal and per capita income very low.
  5.  Due to these crises China ended its political and economic isolation with the establishment of relations with the United States in 1972.

Question.32. “The transition from Communism to Capitalism in Pre-Soviet Republics was not a smooth one.” Explain the statement.
Or
“Non-alignment was a strategy evolved in the Cold War context” With the disintegration of the USSR has it lost its relevance ? Highlight any two suitable arguments in support of your answer.
Answer. The Shock-Therapy was the State of affairs which signifies the collapse of communism followed by a painful process of transition from an authoritarian socialist system to a democratic capitalist system. The model of transition in Russia, Central Asia and East Europe was influenced by the World Bank and the IMF.
‘Shock Therapy’ varied in intensity and speed amongst the former second world countries but its direction and features were quite similar.
Capitalist Economy: The shock-Therapy advocated that every country was required to make a total shift to capitalist efonomy i.e. the private ownership became a dominant pattern of ownership of property.
Private farming : Shock-Therapy involved the replacement of collective farming to private farming and capitalism in agriculture.
Free Trade: Shock-Therapy stressed on the external orientation of the economies with the free trade as the essential condition. The free trade regime and foreign direct investment [FDI] became the main engines of change. ‘
Trade alliances with west: Shock-Therapy transition also involved a break-up of the existing trade alliances among the countries of the Soviet Bloc. Each state from the bloc was supposed to be directly linked to the west instead of inter-trade alliance among the regions.
The western capitalist states now got the dominant position and thus guided and controlled the economic development of the regions.
The above features of the Shock-Therapy show the transition from authoritarian socialist system to a democratic capitalist system.
Or
Non-alignment as a strategy evolved in the Cold War context, but the end of “Cold War” and a Unipolar world did not see thd end of the non-alignment.
Non-alignment still contains some core values and end-using ideas.

  1. Its emphasis has shifted from “political issues to economic issues”.
  2.  Liberalisation of third world economies for rapid development of the countries of south now remains the main concern of NAM.
  3.  Issues like democracy, disarmament, human rights and neo-colonialism are as relevant today as earlier.
    With the disintegration of the erstwhile USSR, there is only one super power therefore, it is very essential for NAM to make sincere efforts to check USA from taking unilateral decisions.
  4. Now its emphasis has also shifted towards poverty alleviation, New International Economic Order (NIEO) based on equality, equity and justice and promotion of industrialisation.
    NAM must make efforts’to reshape and democratise the United Nations so that the domination of powerful countries is checked.
    Besides, NAM must ensure that in the era of Globalisation, liberalism and explosion of Information Technology (IT), the developed and developing nations derive the maximum benefit and are not allowed to be exploited.
    Therefore, the concept of non-alignment is applicable even in normal situation. Its essence is that every international issue is discussed on merit. This is an attitude which must be reflected in international affairs.

CBSE Class 9 Maths Lab Manual – Comparison of Diagonals in Different Quadrilaterals

Objective
To explore the similarities and differences between the different quadrilaterals like parallelogram, rectangle, rhombus and square with respect to their diagonals.

Prerequisite Knowledge
Properties of parallelogram, rectangle, square, rhombus.

  1. In parallelogram, diagonals are not equal.
  2. In rectangle, diagonals are equal.
  3. In rhombus, diagonals are not equal but bisect each other at 90°
  4. In square, diagonals are equal and bisect each other at 90°.

Materials Required
Glazed papers, ruler, a pair of scissors, pencil, tracing paper.

Procedure
Case I:

  1. Make a parallelogram on a glazed paper by paper folding and name it as ABCD. Join AC and BD.
  2. Draw and cut replicas of AABC and ABCD. Coincide the diagonals AC and BD.
    CBSE Class 9 Maths Lab Manual – Comparison of Diagonals in Different Quadrilaterals 1
    CBSE Class 9 Maths Lab Manual – Comparison of Diagonals in Different Quadrilaterals 2
    Observation:
    We observe that diagonal AC ≠ diagonal BD.

Case II

  1. Make a rectangle by paper folding on a glazed paper. Name it as PQRS. Join PR and QS.
  2. Cut replicas of ∆PQS and ∆PQR and name them as ∆BCA and ∆EFD.
    CBSE Class 9 Maths Lab Manual – Comparison of Diagonals in Different Quadrilaterals 3
    3. Place two replicas such that AC and ED coincise eachother and side AB is opposite to side FD.
    CBSE Class 9 Maths Lab Manual – Comparison of Diagonals in Different Quadrilaterals 4
    Observation:
    Here we notice that AC = DE. (as they overlap each other)
    ∴ diagonal AC = diagonal DE
    ∴ QS = PR

Case III:

  1. Make a rhombus by paper folding on a glazed paper. Name it as ABCD. Join AC and BD.
  2. Draw and cut replicas of ∆ABC and ∆DCB and name them as ∆PQR and ∆MNO’ respectively.
    CBSE Class 9 Maths Lab Manual – Comparison of Diagonals in Different Quadrilaterals 5
    CBSE Class 9 Maths Lab Manual – Comparison of Diagonals in Different Quadrilaterals 6
  3. Place two replicas such that PR and MO’ coincide each other.
    CBSE Class 9 Maths Lab Manual – Comparison of Diagonals in Different Quadrilaterals 7
    Observation:
    We observe thatPR ≠ O’M.
    ∴ diagonal AC ≠ diagonal BD
  4. Draw and cut replicas of ∆AOB and ∆BOC and verify the congruency of two triangles by placing one over other.
    CBSE Class 9 Maths Lab Manual – Comparison of Diagonals in Different Quadrilaterals 8
    Here BC = AB
    OB = BO
    OC = OA
    ∴∆BOC = ∆BOA
    ∴∠BOC = ∠BOA
    ∴∠BOC + ∠BOA = 180° (linear pair angles)
    2∠BOC = 180° [from (i)]
    ∴ ∠BOC = 90°
    Thus, it is verified that in a rhombus, diagonals are not equal but bisect each other at 90°.

Case IV:

  1. Make a square by paper folding on a glazed paper. Name it as PQRS. Join PR and SQ.
  2. Draw and cut replicas of ∆PQS and ∆PQR.
    CBSE Class 9 Maths Lab Manual – Comparison of Diagonals in Different Quadrilaterals 9
  3. Place two replicas along their diagonals SQ and PR. Here, we observe that both diagonals overlap each other completely. Thus, diagonal SQ = diagonal PR.
  4. Draw and cut replicas of ∆POQ and ∆POS. Place these replicas as shown in fig. below.
    CBSE Class 9 Maths Lab Manual – Comparison of Diagonals in Different Quadrilaterals 10
    Observation:
    Here, PQ = SP (sides of a square)
    OP = OP (common side)
    OQ = OS (By observation)
    ∆POQ = ∆POS (By SSS)
    ∴ ∠POQ = ∠POS (C.P.C.T.)
    But ∠POQ + ∠POS = 180° (linear pair angles)
    2∠POQ = 180°
    ∠POQ = 90°
    This implies that in a square, diagonals are equal and bisect each other at 90°.

Observation
By paper folding and cutting activity it is very much clear that rectangle, square, rhombus and parallelogram differ by their diagonal properties.
In parallelogram, diagonals are not equal, in rectangle diagonals are equal, in rhombus diagonals are not equal but bisect each other at 90°, in square, diagonals are equal and bisect each other at 90°.

Result
We verified that, in parallelogram diagonals are not equal, in square diagonals are equal and bisect each other at 90°. In rectangle diagonals are equal and bisect each other at 90°. In rhombus, diagonals are not equal but bisect at 90°. In this way these figures differentiate each other on the basis of their diagonals.

Learning Outcome
Though square, rectangle and rhombus all have the properties of parallelogram but they are different on the basis of their diagonals.

Activity Time
Draw all types of quadrilaterals on the same plane by using different glazed paper.

Q – Quadrilateral
P – Parallelogram
Re – Rectangle
R – Rhombus
S – Square
We conclude that, all squares are rhombus, rectangle and parallelogram.
