SET I

SECTION-A
(Reading, Writing and Comprehending)

Question.1.Read the following passage and answer the questions that follow:

1. Too many parents these days can’t say no. As a result, they find themselves raising children who respond greedily to the advertisements aimed right at them. Even getting what they want doesn’t satisfy some kids ; they only want more. Now, a growing number of psychologists, educators and parents think it’s time to stop the madness and start teaching kids about what’s really important: values like hard work, contentment, honesty and compassion. The struggle to set limits has never been tougher – and the stakes have never been higher. One recent study of adults who were overindulged as children, paints a discouraging picture of their future : when given too much too soon, they grow up to be adults who have difficulty coping with life’s disappointments. They also have a distorted sense of entitlement that gets in the way of success in the workplace and in relationships.
2. Psychologists say that parents who overindulge their kids set them up to be more vulnerable to future anxiety and depression. Today’s parents themselves raised on values of thrift and self-sacrifice, grew up in a culture where ‘no’ was a household word. Today’s kids want much more, partly because there is so much more to want. The oldest members of this Generation Excess were born in the late 1980s, just as PCs and video games were making their assault on the family room. They think of MP3 players and flat-screen TVs as essential utilities, and they have developed strategies to get them. One survey of teenagers found that when they crave something new, most expect to ask nine times before their parents give in. By every measure, parents are shelling out record amounts. In the heat of this buying blitz, even parents who desperately need to say no find themselves reaching for their credit cards.
3. Today’s parents aren’t equipped to deal with the problem. Many of them, raised in the 1960s and ‘70s, swore they’d act differently from their parents and have closer relationships with their own children. Many even wear the same designer clothes as their kids and listen to the same music. And they work more hours; at the end of a long week, it’s tempting to buy peace with yes’ and not mar precious family time with conflict. Anxiety about the future is another factor. How do well intentioned parents say no to all the sports gear and arts and language lessons they believe will help their kids thrive in an increasingly competitive world? Experts agree: too much love won’t spoil a child. Too few limits will.
4. What parents need to find, is a balance between the advantages of an affluent society and the critical life lessons that come from waiting, saving and working hard to achieve goals. That search for balance has to start early. Children need limits behaviour because they feel better and more secure when they live within a secured structure. Older children learn self-control by watching how others, especially their parents act. Learning how to overcome challenges, is essential to becoming a successful adult. Few parents ask kids to do chores. They think their kids are already overburdened by social and academic pressures. Every individual can be of service to others, and life has meaning beyond one’s own immediate happiness. That means parents eager to teach values have to take a long, hard look at their own.

(iii) Children of present time want more because of increasing desire. Their priorities lies in attaining luxury which they try to acquire through unmitigated strategy.
(iv) In today’s world, there is an exigent need for parents to strike a balance between the advantages of an affluent society and the critical life lessons that come from waiting, saving and working hard to achieve goals.

(b) (i) Contentment .
(ii) Precious
(iii) Essential.

Question.2. Read the passage carefully:

1. I remember my childhood as being generally happy and can recall experiencing some of the most carefree times of my life. But I can also remember, even more vividly, moments of being deeply frightened. As a child, I was truly terrified of the dark and getting lost. These fears were very real and caused me some extremely uncomfortable moments.
2. May be it was the. strange way in which things looked and sounded familiar in my room at night that scared me so much. There was never total darkness, but a street light or passing car lights made clothes hung over a chair take on the shape of an unknown beast. Out of the corner of my eye, I saw curtains move when there was no breeze. A tiny creak in the floor would sound a hundred times louder than in the daylight and my imagination would take over, creating burglars and monsters. Darkness always made me feel helpless. My heart would pound and I would lie very still so that ‘the enemy’ wouldn’t discover me.
3. Another childhood fear of mine was that I would get lost, especially on the way home from school. Every morning, I got fin the school bus right near my home — that was no problem. After school, though, when all the buses were lined up along the curve, I was terrified that I would get on’ the wrong one and be taken to some unfamiliar neighbourhood. I would scafl the bus for the faces of my friends, make sure that the bus driver was the same one that had been there in the morning,, and even then ask the others over and over again to be sure I was in the right bus. On school or family trips to an amusement park or a museum, I wouldn’t let the leaders out of my sight. And of course, I was never very adventurous when it came to taking walks or hikes because I would go only where I was sure I would never get lost.
4. Perhaps, one of the worst fears I had as a child was that of not being liked or accepted by others. First of all, I was quite shy. Secondly, I worried constantly about my looks, thinking people wouldn’t like me because I was too fat or wore braces. I tried to wear ‘the right clothes’ and had intense arguments with my mother over the importance of wearing flats instead of saddled shoes to school. Being popular was very important to me then, and the fear of not being liked was a powerful one.
5. One of the processes of evolving from a child to an adult is being able to recognize and overcome our fears. I have learnt that darkness does not have to take on a life of its own, that others can help me when I am lost and that friendliness and sincerity will encourage people to like me. Understanding the things that scared us, as children helps to cope with our lives as adults.

OR

Answer.
Health Care for Indian Workers
Good morning to all. Recently, I had read an article in the local newspaper “The Hindu” and wondered why we don’t care for the health of the workers around us. We remain mute spectators to their misery trials and tribulations of life.
Often, the workers are found working in inhuman conditions, neglecting their health. They are exploited, are illiterate and lack awareness of a hygienic way of life. The authorities must ensure clean and healthy working conditions for these people. It is the responsbility of the government to provide affordable healthcare services to wdrkers and their families. Indian workers should be taught the importance of cleanliness and hygiene. Many non-governmental organizations can play a role in spreading awareness about health and hygiene. Workers play a major role in our life. We must understand and appreciate their contribution towards society. Access to basic health facilities is their innate right. As responsible citizens, we should get together to make their lives healthy. However, we should not forget that it is the sweat and blood of these workers which has provided us with enormous comfort while we sit in our well-furnished homes.

Impact of Media
Good morning everybody. Today, I am here to voice my concerns on how Media influences public opinion.
Media acts as a powerful weapon-in democracy. It keeps people abreast with the recent changes and development in the society and the world. They also help people understand the various developments and build their opinion about the same. With the development of better modes of communications, the influence of media has increased.Consequently, its responsibility of delivering correct information has also increased. If people blindly believe the biased news which the print and electronic media tell us, our democracy may suffer badly. Media has the power to showcase both the facets of a piece of information. It should work towards helping the common man understand the pros and cons of any issue of event.
Thus, one can clearly say that it is the responsibility of Media and the Media personnel to ensure that they direct their efforts towards building a constructive and balanced society as well as a nation.
Thank you

Her ashen like mother irks her so much that for a moment she ponders over the past memories to feel solace.
(b) The exotic moment the author talks about is when everyone keeps quiet and still. The moment would be extraordinarily tranquil, with no hustle bustle of the frenzied world. Although it may seem little strange in the beginning, it would eventually bring us all together. Ultimately, this is the introspection which makes one united with one’s soul.

(f) How was the skunk’s story different from the other stories narrated by Jack?
(g) Which words of her brother made a deep impression on Bama?
Answer.

(c) Mukesh who hailed from the city of Dhaka was different
from other bangle makers of Firozabad because he liked to dream, unlike others who followed the family lineage of making bangles, he wanted to be a motor mechanic and drive cars.

Thus, the story sends the message that with positive attitude and strength of will, one can accomplish everything in life. All of us are in the grip of fear. But fear, when conquered through courage, becomes victory which has its own charm. It might appear to be long and arduous journey, but it will definitely culminate in success.

OR
After Independence India has seen a steep upward trend in the graph of corruption. The public has often become disgusted and disappointed. As Venkat, a well known journalist, write a speech in 150-200 words on ‘Corruption, its causes and solutions.
Answer.
Youth, Their Problems and Solutions
Good Morning ! I am Sampreet and, as an educationist it is my duty to throw light, on the disturbing trend of the youth becoming more and more frustrated in dealing with stress.
Aspirations are now high and with this the level of competition and peer pressure among the youth has been increasing with each passing day. The youth is either not yet mature or trained enough to handle so much stress and therefore, they ultimately get frustrated, easily commit suicide, road rage, hatred crimes, drug abuse, looting, rapes etc. At the slightest provocation, they hold out protests and demonstrations. The minimum desired level of tolerance is missing in them. They don’t see any harm violating the norms and fundamental rules.
The solution is a doddle one. The youth of today needs our unstinted support; it needs to know that, irrespective of the situation they are in; they are always loved by their parents, teachers and elders. They need to develop confidence in their capabilities. We need to remove the unnecessary pressure that our education system exerts on the young minds; it needs to be eased and, CCE is a positive step in this direction. Counselors can help the young generation understand and solve their problems. More job opportunities have to be. created; better recruitment processes need to be developed; and professional courses that equip them with necessary skills have to be designed.
The most important thing is to impart value based education so that they have high self-esteem, tolerance and patience and more importantly the zeal to create a clean and civilized society and to be good citizens.
OR
Corruption, its Causes and Solutions
Good morning, friends! I am Venkat. As a journalist and responsible citizen of India, it is my duty to shed light and apprise you, how corruption exists in almost every nook and corner of our country.
Corruption can be understood as misappropriation of government or public property or money. It is an unlawful and immoral act. Corruption has had a gradual growth in our country. How and why did corruption become so common in our country? India’s colonial past has contributed in flourishing corrupt practices. It is said that corruption cannot survive long in this world. Although with the increase in scientific technology and advancement of the nation, corruption still remains unbeatable. Also, it is not difficult to visualize. The Corrupter also has a relation with scarcity and corruption exists especially because of the vested interests and greed of the people in power.
It is the spasmodic snare of corruption which springs from all prodigality and dissipation. Whatever the reason may be, corruption is an ill practice that is seen as the major hindrance in the process of economic growth and modernization of the nation. The need for an anti-corruption bill like Jan Lokpal has long been discerned now. But, in a Democracy like India^ the power of the common man should not be underestimated. Constant vigil and intervention by the civil society is also required to bring positive changes in the country. Punishment must be increased and illegally confiscated wealth must be recovered. As aware citizens and of course as a united whole, we must overcome our fears and work towards bringing about a corruption free society.

Subject: Unauthorized Parking of Vehicles
Dear Sir,
This is to draw your attention towards the problems faced due to unauthorized parking of the vehicles in our area. There is not a single day when the place is without disorder or free from trafifc jams. As it is a crowded place, there is inadequate parking space. It creates problems not only to the residents but also to the people who come to meet their relatives or for some other purpose. As it is a busy area, vehicles are parked all over in a haphazard manner. It often results in quarrel among people which displays the lack of civic sense in them also creating noise pollution. It is therefore necessary to take some action and provide the proper parking area to the residents as well as do some arrangements for the visitors too.
We all hope for an immediate action to get respite from this problem. ,
Thanking You
Yours Sincerely,
Rohini (Resident, Sakinaka)

Question.10. What were Sophie’s plan for her future? Why would you call her dreams unrealistic ? (100-125 words)
OR
What benefits did Derry reap from his association with Mr. Lamb?
Answer. Sophie was a day dreamer although she belonged to a middle class family. She was blind to the bitter truth of life. She dreamt of an imaginary life, full of beautiful things in which she owned a boutique. 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. She only thought of impractical things. The house in which she lived was also not very good and her father was working hard to earn bread for the family. They entertained themselves by watching the United team’s matches. Thus, she wanted to achieve the impossible.
OR
Derry had no association with the outer world till he met Mr. Lamb. His meeting with Mr. Lamb was a turning point in his life. He learnt to live a respectful life and also appreciated Mr. Lamb’s attitude and outlook towards people and life. He realized his true worth. Mr. Lamb inspired him to face the world in spite of his disability. Derry’s thinking towards people and life completely changed and he became self-confident. Mr, Lamb successfully infused in him courage and the self-determination. He advised him to ignore the comments made by people on his physical impairment and enjoy beauty of life and nature. That was why Derry went back to Mr. Lamb’s garden in spite of his mother’s refusal. Now, Derry had understood the importance and true meaning of life and understanding himself better than before.

SET I

SECTION-A
(Reading, Writing and Comprehending)

1.Read the following passage and answer the questions that follow:

1. Too many parents these days can’t say no. As a result, they find themselves raising children who respond greedily to the advertisements aimed right at them. Even getting what they want doesn’t satisfy some kids ; they only want more. Now, a growing number of psychologists, educators and parents think it’s time to stop the madness and start teaching kids about what’s really important: values like hard work, contentment, honesty and compassion. The struggle to set limits has never been tougher – and the stakes have never been higher. One recent study of adults who were overindulged as children, paints a discouraging picture of their future : when given too much too soon, they grow up to be adults who have difficulty coping with life’s disappointments. They also have a distorted sense of entitlement that gets in the way of success in the workplace and in relationships.
2. Psychologists say that parents who overindulge their kids set them up to be more vulnerable to future anxiety and depression. Today’s parents themselves raised on values of thrift and self-sacrifice, grew up in a culture where ‘no’ was a household word. Today’s kids want much more, partly because there is so much more to want. The oldest members of this Generation Excess were born in the late 1980s, just as PCs and video games were making their assault on the family room. They think of MP3 players and flat-screen TVs as essential utilities, and they have developed strategies to get them. One survey of teenagers found that when they crave something new, most expect to ask nine times before their parents give in. By every measure, parents are shelling out record amounts. In the heat of this buying blitz, even parents who desperately need to say no find themselves reaching for their credit cards.
3. Today’s parents aren’t equipped to deal with the problem. Many of them, raised in the 1960s and ‘70s, swore they’d act differently from their parents and have closer relationships with their own children. Many even wear the same designer clothes as their kids and listen to the same music. And they work more hours; at the end of a long week, it’s tempting to buy peace with yes’ and not mar precious family time with conflict. Anxiety about the future is another factor. How do well intentioned parents say no to all the sports gear and arts and language lessons they believe will help their kids thrive in an increasingly competitive world? Experts agree: too much love won’t spoil a child. Too few limits will.
4. What parents need to find, is a balance between the advantages of an affluent society and the critical life lessons that come from waiting, saving and working hard to achieve goals. That search for balance has to start early. Children need limits behaviour because they feel better and more secure when they live within a secured structure. Older children learn self-control by watching how others, especially their parents act. Learning how to overcome challenges, is essential to becoming a successful adult. Few parents ask kids to do chores. They think their kids are already overburdened by social and academic pressures. Every individual can be of service to others, and life has meaning beyond one’s own immediate happiness. That means parents eager to teach values have to take a long, hard look at their own.

(i) What values do parents and teachers want children to learn ?
(ii) What are the results of giving the children too much too soon ?
(iii) Why do today’s children want more ?

(v) What is the necessity to set limits for children ?
(b) Pick out words from the passage that mean the same as the following:
(i) A feeling of satisfaction (para 1)
(ii) Valuable (para 3)

(ii) Giving children too much too soon brings its own ill- effects; they grow up to be adults and experience difficulty coping with life’s disappointments. As they are likely to develop a distorted sense of entitlement that hinders their success at work place and in relationships.
(iii) Children of present time want more because of increasing desire. Their priorities lies in attaining luxury which they try to acquire through unmitigated strategy.
(iv) In today’s world, there is an exigent need for parents to strike a balance between the advantages of an affluent society and the critical life lessons that come from waiting, saving and working hard to achieve goals.
(v) There is a necessity to set limits for children because they feel better and more assured when they live within a secured structure and aura.
(b) (i) Contentment .
(ii) Precious
(iii) Essential.

2. Read the passage carefully:

1. I remember my childhood as being generally happy and can recall experiencing some of the most carefree times of my life. But I can also remember, even more vividly, moments of being deeply frightened. As a child, I was truly terrified of the dark and getting lost. These fears were very real and caused me some extremely uncomfortable moments.
2. May be it was the. strange way in which things looked and sounded familiar in my room at night that scared me so much. There was never total darkness, but a street light or passing car lights made clothes hung over a chair take on the shape of an unknown beast. Out of the corner of my eye, I saw curtains move when there was no breeze. A tiny creak in the floor would sound a hundred times louder than in the daylight and my imagination would take over, creating burglars and monsters. Darkness always made me feel helpless. My heart would pound and I would lie very still so that ‘the enemy’ wouldn’t discover me.
3. Another childhood fear of mine was that I would get lost, especially on the way home from school. Every morning, I got fin the school bus right near my home — that was no problem. After school, though, when all the buses were lined up along the curve, I was terrified that I would get on’ the wrong one and be taken to some unfamiliar neighbourhood. I would scan the bus for the faces of my friends, make sure that the bus driver was the same one that had been there in the morning,, and even then ask the others over and over again to be sure I was in the right bus. On school or family trips to an amusement park or a museum, I wouldn’t let the leaders out of my sight. And of course, I was never very adventurous when it came to taking walks or hikes because I would go only where I was sure I would never get lost.
4. Perhaps, one of the worst fears I had as a child was that of not being liked or accepted by others. First of all, I was quite shy. Secondly, I worried constantly about my looks, thinking people wouldn’t like me because I was too fat or wore braces. I tried to wear ‘the right clothes’ and had intense arguments with my mother over the importance of wearing flats instead of saddled shoes to school. Being popular was very important to me then, and the fear of not being liked was a powerful one.
5. One of the processes of evolving from a child to an adult is being able to recognize and overcome our fears. I have learnt that darkness does not have to take on a life of its own, that others can help me when I am lost and that friendliness and sincerity will encourage people to like me. Understanding the things that scared us, as children helps to cope with our lives as adults.

Negligent attitude of the people seem to be the order of the day in todays harsh world. Modern society has given birth to indifferent and offensive individuals. People no longer think of the after effects of their negligent activities. They are driven more by their selfish needs.
People seldom follow traffic rules in India and are seen littering the streets with piles of trash. They show no respect for public property. Vandalism, road rage and intolerance are rampant on the streets. Perseverance and patience are rare virtues to be seen in people behind the wheels.
Inculcating a strong civic sense is the need of the hour. Parents must instill civic sense in children at an early age. They must be taught the values of cleanliness, discipline, patience and tolerance. Parents must encourage their children to. keep their surroundings clean as well as should practice what they preach to their children. Children should be taught to respect and abide by the rules as they are the future of the country.
Our country can progress only if we teach right values to our children. As civilized citizen, it becomes the duty of a parent to fathom this dire need and start off this task at the earliest, as family is the beginning institution for a child to learn right thing.

Cruelty to Animals
By Naina .
Animals should be treated with love and compassion. However, we often fail to this duty.
Instances of animal cruelty are on rise in our society. Poachers, mercilessly kill animals for their skin, fur and teeth. This has led to the extinction of several species of animals which, has affected the ecological balance of our planet. Several companies use animals for testing medicines and cosmetics. Similarly, animals are often ill-treated and forced into performing circus tricks and other activities for our entertainment. Even “The Tiger” one of the endangered species, is on the verge of being extinct. ‘ .
We must understand that co-existence and harmony between humans and animals is essential for our planets survival. We ) must be more responsible and protective towards animals. 111
treatment with animals is act of barbarism which is beyond the limit of one’s conscientiousness. We must learn to love them and treat them as loving creatures. Animals lack power of expression like humans but they possess feelings of pain and agony. It is time that we reform our ways towards the animals. Immediate steps should be taken by the government to ensure proper care, protection and shelter for these animals.

10. Answer any one of the following in 100-125 words :
Why is the Champaran episode considered to be the beginning of the Indian struggle for Independence ?
OR
What was the General’s plan to get rid of the American prisoner ? Was it executed ? What traits of the General’s character are highlighted in the lesson ‘The Enemy ?
Answer. The episode of Champaran was considered to be the beginning of the Indian struggle for Independence because, for the first time, the farmers and peasants rose against the Britishers. The peasants were oppressed by their British landlords, but they lacked the courage to protest. Under the leadership of Gandhiji, they became aware of their rights. A small farmer, Rajkumar Shukla, from a small district, Champaran, helped to bring about a very prominent change. He championed the cause of Champaran movement. Likewise, many other peasants from the villages fought courageously and contributed in their own way to the movement. Their combined effort eventually helped them to win the battle of Champaran and to finally free themselves from ‘Share Cropping’ arrangement. The success also proved, for the first time, the effectiveness of Gandhi’s method of non-violence and non-cooperation. Gandhiji exulted over them and made the villagers feel self-dependant and undaunted.
OR
The General planned to kill the American prisoner by sending his personal assassins and then removing his body from Sadao’s house. The plan was not executed because the General forgot his promise to send the assassins.
The old General had a long expressionless face, which seemed to reflect the cold and calculated ruthlessness, of the man as a general. He had an unusual sense of humour and seemed to generate fear in others hearts quite effortlessly. In his interaction with Sadao, he came across as a man who puts his self-interest above everything else. As Sadao was the only person whom he trusted with his operation, he lets Sadao off the hook. His cold and calculating streak was manifested in the meticulousness with which he latched out the plan of executing the American prisoner of war whom Sadao had given refuge.

11. Both Deny and Lamb are physically impaired and lonely. It is the responsibility of society to understand and support people with infirmities so that they do not suffer from a sense of alienation. As a responsible citizen, write in about 100 words what you would do to bring about a change in the lives of such people.
Answer . In the story, Both Derry and Lamb are physically impaired and lonely. Such people can only live their lives with respect and honour, if they are not ridiculed and punished with heartless pity. These people expect empathy, rather than sympathy, from others. If everyone looks down at them with a pessimistic approach, they may never be able to come out of their sorrow; consequently, they may recline to their own secluded worlds. As responsible citizens, we should understand the tremendous mental and emotional pressure these people go through. Instead of reminding them of their disabilities, we should give them the chance to live a normal life.

Terrorism is one of the major threats that is faced by our country. We live under constant fear of violence and death. Common man feels no longer safe. At every nook and corner, lurks the threat of an imminent terrorist attack. It is a giant threat that the world is confronted with. Activities of terrorists have created a horrendous grief in the hearts of the common masses.
Some of the factors that have given rise to terrorism are lack of education, employment, poor economy and religious difference. But it is high time that we join hands to fight and combat terrorism. India has always boasted of its unity in diversity. Keeping this in view, we need to spread the message of peace and harmony across the nation.
Strengthening the intelligence network, proper policy formation and effective implementation of Prevention of Terrorism Act (POTA) are some of the steps that can be taken up to reduce terrorist attacks. It is also necessary to educate the masses and make them aware of safety measure. It is the need of the hour to keep a constant vigil on the safety of our very own nation.

India is a tourists’ paradise. But we have not really exploited our tourism possibilities. Write an article in 125-150 words on ‘Tourism in India’. You are Ravi/Rani.
Answer. TOURISM IN INDIA
By Ravi
India is known for its rich flora and fauna, beautiful landscapes, glorious past and varied cultural trends. All these make India a major attraction for tourists from all over the world. Tourists from far-away places visit our motherland and are influenced by its scintillating beauty. However, tourism in India has been constantly suffering setbacks due to the various factors.
Pot-holed and filthy roads, rickety buses, over-charged taxis and delayed trains make travelling a nightmare in India. Moreover, the absence of decent and hygienic accommodations at a reasonable cost adds to the distress of tourists visiting India. Besides, the growing menace of terrorism is a huge deterrent and hindrance for tourists.
The government of India needs to put concerted efforts to revamp and rejuvenate tourism in the country. Utmost emphasis should be placed on infrastructure development and increasing, the security. Such effects will certainly make India leader in the world of tourism.

OR
Explain the reactions of the servants in Dr. Sadao’s house when he decided to give shelter to an enemy in the house.
Answer . Gandhiji was not satisfied with mere political and economic solution so he wanted to. bring about a change in the social and cultural conditions of Champaran. He noticed the unhealthy living conditions and poor sanitation in the village. He also realized the need for literacy. He decided to stay * in Champaran even after the disappearance of Indigo Share Cropping. A small farmer, Rajkumar Shukla, from a small district of Champaran, helped bring about a very prominent change.
He opened up schools in six different villages; and several of his disciples and family members volunteered as teachers. Being a staunch believer of passive resistance, he championed the cause of the Champaran movement. His wife, Kasturba, worked on the personal cleanliness and community sanitation of the place. Gandhiji also hired a doctor for the improvement of the health conditions.
Thus, we can say that Gandhiji was not a loyalty to abstractions. It was loyalty to living, human beings. This also made him keen to eradicate social and cultural backwardness of Champaran. Gandhiji exulted over them and made the villages feel self-dependent and undaunted.
OR
When Dr. Sadao decided to give shelter to the enemy, his servants at his house overtly expressed their disapproval. However, they did not disclose the secret to the world. For them, the white man was an enemy who did not deserve their help. Yumi, the nanny of the children, refused to wash the American who was bleeding profusely. The servants expressed this displeasure and they voiced their opinionJoudly for Sadao and Hana to hear. The servants constantly pressurized the Hoki family to let out the secret and get the American caught by the police. Finally, their displeasure at their master’s decision made them decide to leave his household.
