Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42. THE DIGITAL DIVIDEInformation technology is influencing the way many of us live and work today. We use the Internet to look and apply for jobs, shop, conduct research, make airline reservations, and explore areas of interest. We use e-mail and the Internet to communicate instantaneously with friends and business associates around the world. Computers are commonplace in homes and the workplace.Although the number of Internet users is growing exponentially each year, most of the world’s population does not have access to computers or the Internet. Only 6 percent of the population in developing countries are connected to telephones. Although more than 94 percent of U.S. households have a telephone, only 42 percent have personal computers at home and 26 percent have Internet access. The lack of what most of us would consider a basic communications necessity –the telephone –does not occur just in developing nations. On some Native American reservations only 60 percent of the residents have a telephone. The move to wireless connections may eliminate the need for telephone lines, but it does not remove the barrier to equipment costs.Who has Internet access? Fifty percent of the children in urban households with an income over $75,000 have Internet access, compared with 2 percent of the children in low-income, rural households. Nearly half of college-educated people have Internet access, compared to 6 percent of those with only some high school education. Forty percent of households with two parents have access; 15 percent of female, single-parent households do. Thirty percent of white households, 11 percent of black households, and 13 percent of Hispanic households have access. Teens and children are the two fastest-growing segments of Internet users. The digital divide between the populations who have access to the Internet and information technology tools is based on income, race, education, household type, and geographic location. Only 16 percent of the rural poor, rural and central city minorities, young householders, and single parent female households are connected..Another problem that exacerbates these disparities is that African-Americans, Hispanics, and Native Americans hold few of the jobs in information technology. Women hold about 20 percent of these jobs and are receiving fewer than 30 percent of the computer science degrees. The result is that women and members of the most oppressed ethnic groups are not eligible for the jobs with the highest salaries at graduation. Baccalaureate candidates with degrees in computer science were offered the highest salaries of all new college graduates in 1998 at $44,949.Do similar disparities exist in schools? More than 90 percent of all schools in the country are wired with at least one Internet connection. The number of classrooms with Internet connections differs by the income level of students. Using the percentage of students who are eligible for free lunches at a school to determine income level, we see that nearly twice as many of the schools with more affluent students have wired classrooms as those with high concentrations of low-income students. Access to computers and the Internet will be important in reducing disparities between groups. It will require greater equality across diverse groups whose members develop knowledge and skills in computer and information technologies. If computers and the Internet are to be used to promote equality, they will have to become accessible to populations that cannot currently afford the equipment which needs to be updated every three years or so. However, access alone is not enough. Students will have to be interacting with the technology in authentic settings. As technology becomes a tool for learning in almost all courses taken by students, it will be seen as a means to an end rather than an end in itself. If it is used in culturally relevant ways, all students can benefit from its power.Which of the sentences below best expresses the information in the statement “Although the number ............. or the Internet.” in the paragraph 2?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.American movies create myths about college life in the United States. These stories are entertaining, but they are not true. You have to look beyond Hollywood movies to understand what college is really like. Thanks to the movies, many people believe that college students party and socialize more than they study. Movies almost never show students working hard in class or in the library. Instead, movies show them eating, talking, hanging out, or dancing to loud music at wild parties. While it is true that American students have the freedom to participate in activities, they also have academic responsibilities. In order to succeed, they have to attend classes and study hard.Another movie myth is that athletics is the only important extracurricular activity. In fact, there is a wide variety of nonacademic activities on campus such as special clubs, service organizations, art, and theater programs. This variety allows students to choose what interests them. Even more important, after graduation, students’ résumés look better to employers if they list a few extracurricular activities.Most students in the movies can easily afford higher education. If only this were true! While it is true that some American college students are wealthy, most are from families with moderate incomes. Up to 80% of them get some type of financial aid. Students from middle and lower-income families often work part-time throughout their college years. There is one thing that many college students have in common, but it is not something you will see in the movies. They have parents who think higher education is a priority, a necessary and important part of their children's lives.Movies about college life usually have characters that are extreme in some way. super athletic, super intelligent, super wealthy, super glamorous, etc. Movies use these stereotypes, along with other myths of romance and adventure because audiences like going to movies that include these elements. Of course, real college students are not like movie characters at all.So the next time you want a taste of the college experience, do not go to the movies. Look at some college websites or brochures instead. Take a walk around your local college campus. Visit a few classes. True, you may not be able to see the same people or exciting action you will see in the movies, but you can be sure that there are plenty of academic adventures going on all around you !The word “moderate” in the fourth paragraph is closest in meaning to “_______”.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.           Family life in the United States is changing. Thirty or forty years ago, the wife was called a "housewife". She cleaned, cooked, and cared for the children. The husband earned the money for the family. He was usually out working all day. He came home tired in the evening, so he did not do much housework. And he did not see the children very much, except on weekends.          These days, however, more and more wemen work outside the home. They cannot stay with the children all day. They, too, come home tired in the evening. They do not want to spend the evening cooking dinner and cleaning up. They do not have time to clean the house and do the laundry. So who is going to do the housework now? Who is going to take care of the children?          Many families solve the problem of housework by sharing it. In these families, the husband and wife agree to do different jobs around the house, or they take turns doing each job. For example, the husband always cooks dinner and the wife always does the laundry. Or the wife cooks dinner on some nights and the husband cooks dinner on other nights.          Then there is a question of the children. In the past, many families got help with child care from grandparents. Now families usually do not live near their relatives. The grandparents often are too far away to help in a regular way.          More often, parents have to pay for child care help. The help may be a babysister or a day-care center. The problem with this kind of help is the high cost. It is possible only for couples with jobs that pay well. Parents may get another kind of help from the companies they work for. Many companies now let people with children work part-time. That way, parents can spend more time with their children. Some husbands may even stop working for a while to stay with the children. For these men there is a new word: They are called "househusband". In the United States more ans more men are becoming househusband every year.          These changes in the home mean changes in the family. Fathers can learn to understand their children better, and the children can get to know their fathers better. Husbands and wives may also find changes in their marriage. They, too, may have a better understanding of each otherIt can be inferred from paragraph 4 that__________.

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.     Quite different from storm surges are the giant sea waves called tsunamis, which derive their name from the Japanese expression for “high water in a harbor.” These waves are also referred to by the general public as tidal waves, although they have relatively little to do with tides. Scientists often referred to them as seismic sea waves, far more appropriate in that they do result from undersea seismic activity.     Tsunamis are caused when the sea bottom suddenly moves, during an underwater earthquake or volcano for example, and the water above the moving earth is suddenly displaced. This sudden shift of water sets off a series of waves. These waves can travel great distances at speeds close to 700 kilometers per hour. In the open ocean, tsunamis have little noticeable amplitude, often no more than one or two meters. It is when they hit the shallow waters near the coast that they increase in height, possibly up to 40 meters.     Tsunamis often occur in the Pacific because the Pacific is an area of heavy seismic activity. Two areas of the Pacific well accustomed to the threat of tsunamis are Japan and Hawaii. Because the seismic activity that causes tsunamis in Japan often occurs on the ocean bottom quite close to the islands, the tsunamis that hit Japan often come with little warning and can, therefore, prove disastrous. Most of the tsunamis that hit the Hawaiian Islands, however, originate thousands of miles away near the coast of Alaska, so these tsunamis have a much greater distance to travel and the inhabitants of Hawaii generally have time for warning of their imminent arrival.     Tsunamis are certainly not limited to Japan and Hawaii. In 1755, Europe experienced a calamitous tsunami, when movement along the fault lines near the Azores caused a massive tsunami to sweep onto the Portuguese coast and flood the heavily populated area around Lisbon. The greatest tsunami on record occurred on the other side of the world in 1883 when the Krakatoa volcano underwent a massive explosion, sending waves more than 30 meters high onto nearby Indonesian islands; the tsunami from this volcano actually traveled around the world and was witnessed as far away as the English Channel. The passage suggests that the tsunamis resulting from the Krakatoa volcano _____.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.China - Missing Women1. In China the growing difference between the genders is giving signals of alarm to Government authorities. According to the latest census figures, 119 boys are born for every 100 girls. This striking difference is expected to shoot up by the year 2020 with almost 40 million unsettled bachelors. This distribution of the social ecology would create havoc in the future. The social leaders are trying to pressurize the masses into producing more females. The Government has embarked on policies extending innumerable incentives to the families bearing girls. Monetary support, free education, guaranteed employment is being gifted to parents who gift the country with a girl child. The Government is trying to persuade people to suppress their personal preferences and regulate their community behavior according to the new blueprint to stimulate the girl ratio. [A■] Sometimes the Government tries to woo them and sometimes it uses stem policies to force them into it2. Consequent to the population explosion, the Government introduced, in the 80’s, one child policy in China. Any additional pregnancy had to be terminated. This was aimed to put a check on the teeming millions. The policy had no relation to extermination of girl child in the womb. But the policymakers had no idea about its long term impact. People, with a patriarchic mindset, came up with their preference for a single male child. The idea of a happy family became ‘parents with a single male child’.3. The Chinese culture has always promoted sons over daughters because the society has been dominated by males. In villages, where hard work is needed to sustain the agriculture, a boy is always preferable due to his superior physical strength compared to that of a girl. [B■] In such circumstances, looking forward to a male baby seems justified. If people have to limit their families, it is obvious they would prefer a boy over a girl child. This problem has been accentuated by the use of ultrasound scanning which helps determine the sex of the fetus. This technology has played a crucial role in creating gender imbalance.4. Sociologists consider this imbalance as the aftermath of Government’s poorly thought and short-sighted policy. The Government's intentions notwithstanding, China came to develop a markedly lopsided sex ratio. Nobel Laureate Hayek feels that when Government tries to dominate the social system by making people forcibly inculcate a certain habit, such a condition is bound to happen. People try to find ways which not only fulfill their preferences but also satisfy the law makers. The Government damaged the dynamics of a healthy society and was now bearing the brunt of its past deeds.5. Hayek argues that by no means should a centralized bureaucracy be allowed to design preferences for hundreds of thousands of people, without even consulting them. In such a system, with the passage of time, unforeseen consequences spring up. Government can bind people to its chosen course for a time but the impositions cannot limit their options for long. [C■] The quarter century that has passed since commencement of the effort to redesign the Chinese family is leaving behind its own trail.6. The Government needs to be careful now. It has to invent new remedies to address this problem. It needs to redesign the social fabric so that programs like ‘Care for Girls’ get support of the masses, who seem to have little faith in the system. They view the new program for the girl child in the same resigned manner as the program that was forced on them in the past. Some women social workers are of the view that the fall of sex ratio has been an advantage for the women of China, as their social value has increased. [D■] The Government policy has in a way helped uplift the status of females. The real fear now is that China will soon be faced with hordes of bachelors at war with their brethren over finding their brides. The “surplus sons” of China need to stop interfering with the social system.Look at the four squares [■] that indicate where the following sentence can be added to the passage: “Another reason is that daughters have to leave their parents after marriage to enrich their husband's family.” Where would the sentence best fit?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42. THE DIGITAL DIVIDEInformation technology is influencing the way many of us live and work today. We use the Internet to look and apply for jobs, shop, conduct research, make airline reservations, and explore areas of interest. We use e-mail and the Internet to communicate instantaneously with friends and business associates around the world. Computers are commonplace in homes and the workplace.Although the number of Internet users is growing exponentially each year, most of the world’s population does not have access to computers or the Internet. Only 6 percent of the population in developing countries are connected to telephones. Although more than 94 percent of U.S. households have a telephone, only 42 percent have personal computers at home and 26 percent have Internet access. The lack of what most of us would consider a basic communications necessity –the telephone –does not occur just in developing nations. On some Native American reservations only 60 percent of the residents have a telephone. The move to wireless connections may eliminate the need for telephone lines, but it does not remove the barrier to equipment costs.Who has Internet access? Fifty percent of the children in urban households with an income over $75,000 have Internet access, compared with 2 percent of the children in low-income, rural households. Nearly half of college-educated people have Internet access, compared to 6 percent of those with only some high school education. Forty percent of households with two parents have access; 15 percent of female, single-parent households do. Thirty percent of white households, 11 percent of black households, and 13 percent of Hispanic households have access. Teens and children are the two fastest-growing segments of Internet users. The digital divide between the populations who have access to the Internet and information technology tools is based on income, race, education, household type, and geographic location. Only 16 percent of the rural poor, rural and central city minorities, young householders, and single parent female households are connected..Another problem that exacerbates these disparities is that African-Americans, Hispanics, and Native Americans hold few of the jobs in information technology. Women hold about 20 percent of these jobs and are receiving fewer than 30 percent of the computer science degrees. The result is that women and members of the most oppressed ethnic groups are not eligible for the jobs with the highest salaries at graduation. Baccalaureate candidates with degrees in computer science were offered the highest salaries of all new college graduates in 1998 at $44,949.Do similar disparities exist in schools? More than 90 percent of all schools in the country are wired with at least one Internet connection. The number of classrooms with Internet connections differs by the income level of students. Using the percentage of students who are eligible for free lunches at a school to determine income level, we see that nearly twice as many of the schools with more affluent students have wired classrooms as those with high concentrations of low-income students. Access to computers and the Internet will be important in reducing disparities between groups. It will require greater equality across diverse groups whose members develop knowledge and skills in computer and information technologies. If computers and the Internet are to be used to promote equality, they will have to become accessible to populations that cannot currently afford the equipment which needs to be updated every three years or so. However, access alone is not enough. Students will have to be interacting with the technology in authentic settings. As technology becomes a tool for learning in almost all courses taken by students, it will be seen as a means to an end rather than an end in itself. If it is used in culturally relevant ways, all students can benefit from its power.Why does the author mention the telephone in paragraph 2?

In 1755, Europe experienced a calamitous tsunami, when movement along the fault lines near the Azores caused a massive tsunami to sweep onto the Portuguese coast and flood the heavily populated area around Lisbon. The greatest tsunami on record occurred on the other side of the world in 1883 when the Krakatoa volcano underwent a massive explosion, sending waves more than 30 meters high onto nearby Indonesian islands; the tsunami from this volcano actually traveled around the world and was witnessed as far away as the English Channel. A main difference between tsunamis in Japan and in Hawaii is that tsunamis in Japan are more likely to _____.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.American movies create myths about college life in the United States. These stories are entertaining, but they are not true. You have to look beyond Hollywood movies to understand what college is really like. Thanks to the movies, many people believe that college students party and socialize more than they study. Movies almost never show students working hard in class or in the library. Instead, movies show them eating, talking, hanging out, or dancing to loud music at wild parties. While it is true that American students have the freedom to participate in activities, they also have academic responsibilities. In order to succeed, they have to attend classes and study hard.Another movie myth is that athletics is the only important extracurricular activity. In fact, there is a wide variety of nonacademic activities on campus such as special clubs, service organizations, art, and theater programs. This variety allows students to choose what interests them. Even more important, after graduation, students’ résumés look better to employers if they list a few extracurricular activities.Most students in the movies can easily afford higher education. If only this were true! While it is true that some American college students are wealthy, most are from families with moderate incomes. Up to 80% of them get some type of financial aid. Students from middle and lower-income families often work part-time throughout their college years. There is one thing that many college students have in common, but it is not something you will see in the movies. They have parents who think higher education is a priority, a necessary and important part of their children's lives.Movies about college life usually have characters that are extreme in some way. super athletic, super intelligent, super wealthy, super glamorous, etc. Movies use these stereotypes, along with other myths of romance and adventure because audiences like going to movies that include these elements. Of course, real college students are not like movie characters at all.So the next time you want a taste of the college experience, do not go to the movies. Look at some college websites or brochures instead. Take a walk around your local college campus. Visit a few classes. True, you may not be able to see the same people or exciting action you will see in the movies, but you can be sure that there are plenty of academic adventures going on all around you !The phrase “academic responsibilities” in the second paragraph is closest in meaning to “_________ ”.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.China - Missing Women1. In China the growing difference between the genders is giving signals of alarm to Government authorities. According to the latest census figures, 119 boys are born for every 100 girls. This striking difference is expected to shoot up by the year 2020 with almost 40 million unsettled bachelors. This distribution of the social ecology would create havoc in the future. The social leaders are trying to pressurize the masses into producing more females. The Government has embarked on policies extending innumerable incentives to the families bearing girls. Monetary support, free education, guaranteed employment is being gifted to parents who gift the country with a girl child. The Government is trying to persuade people to suppress their personal preferences and regulate their community behavior according to the new blueprint to stimulate the girl ratio. [A■] Sometimes the Government tries to woo them and sometimes it uses stem policies to force them into it2. Consequent to the population explosion, the Government introduced, in the 80’s, one child policy in China. Any additional pregnancy had to be terminated. This was aimed to put a check on the teeming millions. The policy had no relation to extermination of girl child in the womb. But the policymakers had no idea about its long term impact. People, with a patriarchic mindset, came up with their preference for a single male child. The idea of a happy family became ‘parents with a single male child’.3. The Chinese culture has always promoted sons over daughters because the society has been dominated by males. In villages, where hard work is needed to sustain the agriculture, a boy is always preferable due to his superior physical strength compared to that of a girl. [B■] In such circumstances, looking forward to a male baby seems justified. If people have to limit their families, it is obvious they would prefer a boy over a girl child. This problem has been accentuated by the use of ultrasound scanning which helps determine the sex of the fetus. This technology has played a crucial role in creating gender imbalance.4. Sociologists consider this imbalance as the aftermath of Government’s poorly thought and short-sighted policy. The Government's intentions notwithstanding, China came to develop a markedly lopsided sex ratio. Nobel Laureate Hayek feels that when Government tries to dominate the social system by making people forcibly inculcate a certain habit, such a condition is bound to happen. People try to find ways which not only fulfill their preferences but also satisfy the law makers. The Government damaged the dynamics of a healthy society and was now bearing the brunt of its past deeds.5. Hayek argues that by no means should a centralized bureaucracy be allowed to design preferences for hundreds of thousands of people, without even consulting them. In such a system, with the passage of time, unforeseen consequences spring up. Government can bind people to its chosen course for a time but the impositions cannot limit their options for long. [C■] The quarter century that has passed since commencement of the effort to redesign the Chinese family is leaving behind its own trail.6. The Government needs to be careful now. It has to invent new remedies to address this problem. It needs to redesign the social fabric so that programs like ‘Care for Girls’ get support of the masses, who seem to have little faith in the system. They view the new program for the girl child in the same resigned manner as the program that was forced on them in the past. Some women social workers are of the view that the fall of sex ratio has been an advantage for the women of China, as their social value has increased. [D■] The Government policy has in a way helped uplift the status of females. The real fear now is that China will soon be faced with hordes of bachelors at war with their brethren over finding their brides. The “surplus sons” of China need to stop interfering with the social system.How has "One Child Policy" supposedly improved the value of females? (Refer paragraph 6)

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.     Quite different from storm surges are the giant sea waves called tsunamis, which derive their name from the Japanese expression for “high water in a harbor.” These waves are also referred to by the general public as tidal waves, although they have relatively little to do with tides. Scientists often referred to them as seismic sea waves, far more appropriate in that they do result from undersea seismic activity.     Tsunamis are caused when the sea bottom suddenly moves, during an underwater earthquake or volcano for example, and the water above the moving earth is suddenly displaced. This sudden shift of water sets off a series of waves. These waves can travel great distances at speeds close to 700 kilometers per hour. In the open ocean, tsunamis have little noticeable amplitude, often no more than one or two meters. It is when they hit the shallow waters near the coast that they increase in height, possibly up to 40 meters.     Tsunamis often occur in the Pacific because the Pacific is an area of heavy seismic activity. Two areas of the Pacific well accustomed to the threat of tsunamis are Japan and Hawaii. Because the seismic activity that causes tsunamis in Japan often occurs on the ocean bottom quite close to the islands, the tsunamis that hit Japan often come with little warning and can, therefore, prove disastrous. Most of the tsunamis that hit the Hawaiian Islands, however, originate thousands of miles away near the coast of Alaska, so these tsunamis have a much greater distance to travel and the inhabitants of Hawaii generally have time for warning of their imminent arrival.     Tsunamis are certainly not limited to Japan and Hawaii.

Scientists often referred to them as seismic sea waves, far more appropriate in that they do result from undersea seismic activity.     Tsunamis are caused when the sea bottom suddenly moves, during an underwater earthquake or volcano for example, and the water above the moving earth is suddenly displaced. This sudden shift of water sets off a series of waves. These waves can travel great distances at speeds close to 700 kilometers per hour. In the open ocean, tsunamis have little noticeable amplitude, often no more than one or two meters. It is when they hit the shallow waters near the coast that they increase in height, possibly up to 40 meters.     Tsunamis often occur in the Pacific because the Pacific is an area of heavy seismic activity. Two areas of the Pacific well accustomed to the threat of tsunamis are Japan and Hawaii. Because the seismic activity that causes tsunamis in Japan often occurs on the ocean bottom quite close to the islands, the tsunamis that hit Japan often come with little warning and can, therefore, prove disastrous. Most of the tsunamis that hit the Hawaiian Islands, however, originate thousands of miles away near the coast of Alaska, so these tsunamis have a much greater distance to travel and the inhabitants of Hawaii generally have time for warning of their imminent arrival.     Tsunamis are certainly not limited to Japan and Hawaii. In 1755, Europe experienced a calamitous tsunami, when movement along the fault lines near the Azores caused a massive tsunami to sweep onto the Portuguese coast and flood the heavily populated area around Lisbon. The greatest tsunami on record occurred on the other side of the world in 1883 when the Krakatoa volcano underwent a massive explosion, sending waves more than 30 meters high onto nearby Indonesian islands; the tsunami from this volcano actually traveled around the world and was witnessed as far away as the English Channel. The word “displaced” in line 6 is closet in meaning to _____.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.China - Missing Women1. In China the growing difference between the genders is giving signals of alarm to Government authorities. According to the latest census figures, 119 boys are born for every 100 girls. This striking difference is expected to shoot up by the year 2020 with almost 40 million unsettled bachelors. This distribution of the social ecology would create havoc in the future. The social leaders are trying to pressurize the masses into producing more females. The Government has embarked on policies extending innumerable incentives to the families bearing girls. Monetary support, free education, guaranteed employment is being gifted to parents who gift the country with a girl child. The Government is trying to persuade people to suppress their personal preferences and regulate their community behavior according to the new blueprint to stimulate the girl ratio. [A■] Sometimes the Government tries to woo them and sometimes it uses stem policies to force them into it2. Consequent to the population explosion, the Government introduced, in the 80’s, one child policy in China. Any additional pregnancy had to be terminated. This was aimed to put a check on the teeming millions. The policy had no relation to extermination of girl child in the womb. But the policymakers had no idea about its long term impact. People, with a patriarchic mindset, came up with their preference for a single male child. The idea of a happy family became ‘parents with a single male child’.3. The Chinese culture has always promoted sons over daughters because the society has been dominated by males. In villages, where hard work is needed to sustain the agriculture, a boy is always preferable due to his superior physical strength compared to that of a girl. [B■] In such circumstances, looking forward to a male baby seems justified. If people have to limit their families, it is obvious they would prefer a boy over a girl child. This problem has been accentuated by the use of ultrasound scanning which helps determine the sex of the fetus. This technology has played a crucial role in creating gender imbalance.4. Sociologists consider this imbalance as the aftermath of Government’s poorly thought and short-sighted policy. The Government's intentions notwithstanding, China came to develop a markedly lopsided sex ratio. Nobel Laureate Hayek feels that when Government tries to dominate the social system by making people forcibly inculcate a certain habit, such a condition is bound to happen. People try to find ways which not only fulfill their preferences but also satisfy the law makers. The Government damaged the dynamics of a healthy society and was now bearing the brunt of its past deeds.5. Hayek argues that by no means should a centralized bureaucracy be allowed to design preferences for hundreds of thousands of people, without even consulting them. In such a system, with the passage of time, unforeseen consequences spring up. Government can bind people to its chosen course for a time but the impositions cannot limit their options for long. [C■] The quarter century that has passed since commencement of the effort to redesign the Chinese family is leaving behind its own trail.6. The Government needs to be careful now. It has to invent new remedies to address this problem. It needs to redesign the social fabric so that programs like ‘Care for Girls’ get support of the masses, who seem to have little faith in the system. They view the new program for the girl child in the same resigned manner as the program that was forced on them in the past. Some women social workers are of the view that the fall of sex ratio has been an advantage for the women of China, as their social value has increased. [D■] The Government policy has in a way helped uplift the status of females. The real fear now is that China will soon be faced with hordes of bachelors at war with their brethren over finding their brides. The “surplus sons” of China need to stop interfering with the social system.The word “teeming” in paragraph 2 is closest in meaning to
