      Anthropogenic global warming is a theory explaining today's long-term increase in the average temperature of Earth's atmosphere as an effect of human industry and agriculture.
      Since the latter half of the 20th century, growing banks of data and improved climate models have convinced most climate scientists that rising trends in greenhouse gas emissions are directly responsible for a rising trend in atmospheric temperature. The source of these emissions vary, consisting of a mix of gases that include methane and carbon dioxide. While some sources - such as volcanoes - are natural, their overall emissions compared with those produced by human industries, transport, and livestock have been regarded as insignificant over recent centuries.
       Greenhouse gases are made of molecules that absorb electromagnetic radiation, such as  the light reflecting from the planet's surface, and re-emit it as heat. These gases include methane, carbon dioxide, water, and nitrous oxide. Despite making up only a small percentage of the atmosphere's mix of gases they are very important. If we had no naturally occurring greenhouse gases in the atmosphere at all, the average global temperature on Earth would be a much lower -18 degrees instead of the roughly 15 degrees Celsius we have enjoyed most of human history.
        Carbon dioxide levels have steadily risen over the past two centuries, thanks largely to the burning of fossil fuels for electricity general, transportation, and smelting. Current levels are approximately 415 parts per million (ppm), up from pre-industrial levels of around 280 ppm. Models vary in their predictions of further temperature increases, and depend heavily on future trends in greenhouse gas emissions. Conservative estimates by the Intergovernmental Panel on Climate Change predict an even chance of 4 degrees Celsius rise by the end of the century if current emissions trends continue.

According to paragraph 3, what would happen if the Earth were bereft of natural greenhouse gases?

Preparation is a key to a successful interview. Does the idea of going to a job interview make you feel a little nervous? Many people find that it is the hardest part of the employing process. But it is not really true. The more you prepare and practice, the more comfortable you will feel. You should find out as much as possible about the company before you go to the interview. Understand the products that they produce and the services that they provide. It is also good to know who the customers are and who the major competitors are. Practice makes perfect. It will also make you feel more confident and relaxed. So, practice your answers to common questions. Make a list of questions to ask, too. Almost all interviewers will ask if you have questions. This is a great opportunity for you to show your keenness, enthusiasm, and knowledge.
Make a great impression. The interview is your chance to show that you are the best person for the job. Your application or resume has already exhibited that you are qualified. Now it is up to you to show how your skills and experience match this position and this company. The employer will be looking and listening to determine if you are a good fit. He/she will be looking for a number of different qualities, in addition to the skills that you possess. To make the best impression, dress appropriately; express your strengths; arrive early, by about 10-15 minutes; be enthusiastic; shake hands firmly; be an active listener; sit up straight and maintain eye contact; and ask questions 
After the interview, follow up with a thank-you note. This is a chance for you to restate your interest and how you can benefit the company. Your best bet is to try to time it so that the note gets there before the hiring: decision is made. You should also follow up with a phone call if you do not hear back from the employer within the specified time.

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:
The legal limit for driving after drinking alcohol is 80 milligrams of alcohol in 100 milliliters of blood, when tested. But there is no sure way of telling how much you can drink before you reach this limit. It varies with each person depending on your weight, your sex, if you’ve just eaten and what sort of drinks you’ve had. Some people might reach their limit after only about three standard drinks.
In fact, your driving ability can be affected by just one or two drinks. Even if you’re below the legal limit, you could still be taken to court if a police officer thinks your driving has been affected by alcohol.
It takes about an hour for the body to get rid of the alcohol in one standard drink. So, if you have a heavy drinking session in the evening you might find that your driving ability is still affected the next morning, or you could even find that you’re still over the legal limit. In addition, if you’ve had a few drinks at lunchtime, another one or two drinks in the early evening may well put you over the legal limit.
In a test with professional drivers, the more alcoholic drinks they had had the more certain they were that they could drive a test course through a set of moveable posts … and the less able they were to do it!
So the only way to be sure you’re safe is not to drink at all.
Alcohol is a major cause of road traffic accidents. One in three of the drivers killed in road accidents have levels of alcohol which are over the legal limit, and road accidents after drinking are the biggest cause of death among young men. More half of the people stopped by the police to take a breathalyzer test have a blood alcohol concentrate of more than twice the legal limit.
It is important to remember that driving after you’ve been drinking doesn’t just affect you. If you’re involved in an accident it affects a lot of other people as well, not least the person you might kill or injure. 

What does this article urge you to remember particularly about driving and drinking?

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:
Archimedes’s Principle is a law of physics that states that when an object is totally or partially immersed in a fluid, it experiences an upthrust equal to the weight of the fluid displaced. The principle is most frequently applied to the behaviour of objects in water, and helps to explain floating and sinking, and why objects seem lighter in water. It also applies to balloons.
The key word in the principle is “upthrust”, which refers to the force acting upward to reduce the apparent weight of the object when it is under water. If, for example, a metal block with a volume of 100 cm3 is dipped in water, it displaces an equal volume of water, which has a weight of approximately 1 N (3.5 oz). The block therefore seems to weigh about 1 N less.
An object will float if its average density is less than that of water. If it is totally submerged, the weight of the water it displaces (and hence the upthrust on it) is greater than its own weight, and it is forced upward and out of water, until the weight if water displaced by submerged part is exactly equal to the weight of the floating object. Thus a block of wood with a density six tenths that of water will float with six tenths of its volume under water, since at that point the weight of fluid displaced is the same as the blocks’s own weight. If a dense material is made into a suitable shape, it will float because of Archimedes’s principle. A ship floats, whereas a block of iron of the same mass sinks.
It is also because of Archimedes’s principle that ships float lower in the water when they are heavily loaded (more water must be displaced to give the necessary upthrust). In addition, they cannot be so heavily loaded if they are to sail in fresh water as they can if they are to sail in the sea, since fresh water is less dense than sea water, and so more water must be displaced to give the necessary upthrust. This means the ship is lower in the water, which can be dangerous in rough weather.

The word “displaces” in the passage almost means “ ”.

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:
Except for a few unfortunate individuals, no law in this world can go against the fact that for most of us our family is an essential part of our lives. The moment you enter this cruel world, where each man is for himself, there are some near and dear ones out there who will do anything to ensure your happiness. We are nothing more than a vulnerable and fragile object, without someone taking care of us on our arrival in this world. Despite all the odds, your family will take care of your wellbeing, and try their best to provide you the greatest comforts in the worled. No one out there, except your family must forgive the endless number of mistakes you may make in your life. Apart from teaching you forgive and forget
lessons, they are always there for you, when you need them the most.
Family is the only place where children study a lot after school. In school, teachers teach children about the subjects which will help them to find a good job in future. But at home, parents teach children about good habits. They are not only the elements which help the children to shape their personalities but they also prepare them a suitable and bright future.
A good family makes a greater society. Father, mother, and children have to work in order to build a strong family. If any one of them fails, the whole family may collapse. The good name of the whole family can be ruined by a single member of the family. In order to avoid that unhappy scenario, every family member has to work hard and try their best. As a result, they will set good examples for the whole society. Families have a powerful impact on society and societies create countries.

According to the passage, which of the following is TRUE about the relation between family and society?

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:
The first thing to do when you have a trip abroad is to check that your passport is valid. Holders of out–of–date passports are not allowed to travel overseas. Then you can prepare for your trip. If you don't know the language, you can have all kinds of problems communicating with local people. Buying a pocket dictionary can make a difference. You'll be able to order food, buy things in shops and ask for directions. It's worth getting one. Also there's nothing worse than arriving at your destination to find there are no hotels available. The obvious way to avoid this is to book in advance. This can save you money too. Another frustrating thing that can happen is to go somewhere and not know about important sightseeing places. Get a guide book before you leave and make the most of your trip. It's a must.
Then, when you are ready to pack your clothes, make sure they are the right kind. It's no good packing sweaters and coats for a hot country or T–shirts and shorts for a cold one. Check the local climate before you leave.
Also, be careful how much you pack in your bags. It's easy to take too many clothes and then not have enough space for souvenirs. But make sure you pack essentials. What about money? Well, it's a good idea to take some local currency with you but not too much. There are conveniently located cash machines (ATMs) in most big cities, and it's usually cheaper to use them than change your cash in banks. Then you'll have more money to spend. When you are at your destination, other travellers often have great information they are happy to share. Find out what they have to say. It could enhance your travelling experience.

According to the passage, you should do all of the following before leaving EXCEPT

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:
Almost all living things ultimately get their energy from the sun. In a process called photosynthesis, plants, algae, and some other organisms capture the sun's energy and use it to make simple sugars such as glucose. Most other organisms use these organic molecules as a source of energy. Organic materials contain a tremendous amount of energy. As food, they fuel our bodies and those of most other creatures. In such forms as oil, gas, and coal, they heat our homes, run our factories and power our cars.
Photosynthesis begins when solar energy is absorbed by chemicals called photosynthetic pigments that are contained within an organism. The most common photosynthetic pigment is chlorophyll. The bright green color characteristic of plants is caused by it. Most algae have additional pigments that may mask the green chlorophyll. Because of these pigments, algae may be not only green but brown, red, blue or even black.
In a series of enzyme-controlled reactions, the solar energy captured by chlorophyll and other pigments is used to make simple sugars, with carbon dioxide and water as the raw materials. Carbon dioxide is one of very few carbon- containing molecules not considered to be organic compounds. Photosynthesis then converts carbon from an inorganic to an organic form. This is called carbon fixation. In this process, the solar energy that was absorbed by chlorophyll is stored as chemical energy in the form of simple sugars like glucose. The glucose is then used to make other organic compounds. In addition, photosynthesis produces oxygen gas. All the oxygen gas on earth, both in the atmosphere we breathe and in the ocean, was produced by photosynthetic organisms. Photosynthesis constantly replenishes the earth's oxygen supply.
Organisms that are capable of photosynthesis can obtain all the energy they need from sunlight and do not need to eat. They are called autotrophs. Plants are the most familiar autotrophs on land. In the ocean, algae and bacteria are the most important autotrophs. Many organisms cannot produce their own food and must obtain energy by eating organic matter. These are called heterotrophs.

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.

   Different cultures follow their own special customs when a child's baby teeth fall out. In Korea, for example, they have the custom of throwing lost teeth up on the roof of a house. According to tradition, a magpie will come and take the tooth. Later, the magpie will return with a new tooth for the child. In other Asian countries, such as Japan and Vietnam, children follow a similar tradition of throwing their lost teeth onto the roofs of houses.

   Birds aren't the only animals thought to take lost teeth. In Mexico and Spain, tradition says a mouse takes a lost tooth and leaves some money. However, in Mongolia, dogs are responsible for taking teeth away. Dogs are highly respected in Mongolian culture and are considered guardian angels of the people. Tradition says that the new tooth will grow good and strong if the baby tooth is fed to a guardian angel. Accordingly, parents in Mongolia will put their child's lost tooth in a piece of meat and feed it to a dog.

   The idea of giving lost teeth to an angel or fairy is also a tradition in the West. Many children in Western countries count on the Tooth Fairy to leave money or presents in exchange for a tooth. The exact origins of the Tooth Fairy are a mystery, although the story probably began in England or Ireland centuries ago. According to tradition, a child puts a lost tooth under his or her pillow before going to bed. In the wee hours, while the child is sleeping, the Tooth Fairy takes the tooth and leaves something else under the pillow. In France, the Tooth Fairy leaves a small gift. In the United States, however, the Tooth Fairy usually leaves money. These days, the rate is $1 to $5 per tooth, adding up to a lot of money from the Tooth Fairy!

The phrase "the wee hours" in paragraph 3 probably refers to the period of time _____.

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:
By mid-century, there will likely be 9 billion people on the planet, consuming ever more resources and leading ever more technologically complex lives. What will our cities be like? How much will artificial intelligence advance? Will global warming trigger catastrophic changes, or will we be able to engineer our way out of the climate change crisis?
Making predictions is, by nature, a dicey business, but to celebrate the 40th anniversary of Smithsonian magazine Big Think asked top minds from a variety of fields to weigh in on what the future holds 40 years from now. The result is our latest special series, Life in 20 50. Demographic changes in world population and population growth will certainly be dramatic. Rockefeller University mathematical biologist Joel Cohen says it's likely that by 2050 the majority of the people in the world will live in urban areas, and will have a significantly higher average age than people today. Cities theorist Richard Florida thinks urbanization trends will reinvent the education system of the United States, making our economy less real estate driven and erasing the divisions between home and work.
Large migrations from developing countries like Indonesia, Malaysia, Bangladesh, Mexico, and countries in the Middle East could disrupt western governments and harm the unity of France, Germany, Spain, the Netherlands, Poland, and the United Kingdom under the umbrella of the European Union.
And rapidly advancing technology will continue ever more rapidly. According to Bill Mitchell, the late director of MIT's Smart Cities research group, cities of the future won't look like "some sort of science -fiction fantasy" or "Star Trek" but it's likely that "discreet, unobtrusive" technological advances and information overlays, i.e. virtual reality and augmented reality, will change how we live in significant ways. Self-driving cars will make the roads safer, driving more efficient, and provide faster transports. A larger version of driverless cars-driverless trucks-may make long haul drivers obsolete.
Meanwhile, the Internet will continue to radically transform media, destroying the traditional model of what a news organization is, says author and former New York Times Public Editor, Daniel Okrent, who believes the most common kinds of news organizations in the future will be "individuals and small alliances of individuals” reporting and publishing on niche topics.

Which of the following predictions in paragraph 2 is NOT true?

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:
Since the world became industrialized, the number of animal species that have either become extinct or near extinction has increased. Bengal tigers, for instance, which once roamed the jungles in vast numbers, now number only about 2,300. By the year 2025, it is estimated that they will become extinct.
What is alarming about the case of the Bengal tiger is that this extinction will have been caused almost entirely by poachers who, according to some sources, are not always interested in material gain but in personal gratification. This is an example of the callousness that is contributing to the problem of extinction. Animals such as the Bengal tiger, as well as other endangered species, are valuable parts of the world/s ecosystem. International laws protecting animals must be enacted to ensure their survival-and the survival of our planet.
Countries around the world have begun to deal with the problem in various ways. Some countries, in an effort to circumvent the problem, have allocated large amounts of land to animal reserves. They then charge admission prices to help defray the costs of maintaining the parks, and they often must also depend on world organizations for support. This money enables them to invest in equipment and patrols o protect the animals. Another response to the increase in animal extinction is an international boycott of products made from endangered species. This has had some effect, but by itself will not prevent animals from being hunted and killed.a

Which of the following could best replace the word ‘allocated’ in paragraph 3?

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:
Before the grass has thickened on the roadside verges and leaves have started growing on the trees is a perfect time to look around and see just how dirty Britain has become. The pavements are stained with chewing gum that has been spat out and the gutters are  full  of discarded fast food cartons. Years ago I remember travelling abroad and being saddened by the  plastic bags, discarded bottles and soiled nappies at the edge of every road. Nowadays, Britain seems to look at least as bad. What has gone wrong?
The problem is that the rubbish created by our increasingly mobile lives lasts a  lot  longer  than before. If it is not cleared up and properly thrown away, it stays in the undergrowth for years; a semi-permanent reminder of what a tatty little country we have now. Firstly, it is estimated that 10 billion plastic bags have been given to shoppers. These will take anything  from  100  to 1,000 years to rot. However, it is not as if there is no solution to this. A few years ago, the Irish government introduced a tax on non-recyclable carrier bags and in three months reduced their  use by 90%. When he was a minister, Michael Meacher attempted to introduce a  similar arrangement  in Britain. The plastics industry protested, of course. However, they need not have bothered; the  idea was killed before it could draw breath, leaving supermarkets free to give away plastic bags.
What is clearly necessary right now is some sort of combined initiative, both individual and collective, before it is too late. The  alternative is  to  continue sliding downhill until we  have a country that looks like a vast municipal rubbish tip. We may well be at  the  tipping  point.  Yet we know that people respond to their environment. If things around them are clean and tidy, people behave cleanly and tidily. If they are surrounded by squalor, they behave squalidly. No  much  of Britain looks pretty squalid. What will it look like in five years?

The word “alternative” in the last 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:
In most families, conflict is more likely to be about Clothing, music, and leisure time than about more serious matters such as religion and core values. Family conflict is rarely about such major issues as adolescents' drug use and delinquency. Nevertheless, it has been estimated that in about 5 million American families (roughly 20 percent), parents and adolescents engage in intense, prolonged, unhealthy conflict. In its most serious form, this highly stressful environment is associated with a number of negative outcomes, including juvenile delinquency, moving away from home, increased school dropout rates, unplanned pregnancy, membership in religious cults, and drug abuse (Steinberg & Morris, 2001).
Many of the changes that define adolescence can lead to conflict in parent- adolescent relationships. Adolescents gain an increased capacity for logical reasoning, which leads them to demand reasons for things they previously accepted without question, and the chance to argue the other side (Maccoby, 1984). Their growing critical-thinking skills make them less likely to conform to parents' wishes the way they did in childhood. Their increasing cognitive sophistication and sense of idealism may compel them to point out logical flaws and inconsistencies in parents' positions and actions. Adolescents no longer accept their parents as unquestioned authorities. They recognize that other opinions also have merit and they are learning how to form and state their own opinions. Adolescents also tend toward ego- centrism, and may, as a result, be ultra-sensitive to a parent's casual remark. The dramatic changes of puberty and adolescence may make it difficult for parents to rely on their children's preadolescent behavior to predict future behavior. For example, adolescent children who were compliant in the past may become less willing to cooperate without what they feel is a satisfactory explanation.

MOBILE PHONES: ARE THEY ABOUT TO TRANSFORM OUR LIVES?
We love them so much that some of us sleep with them under the pillow, yet we are increasingly concerned that we cannot escape their electronic reach. We use them to convey our most intimate secrets, yet we worry that they are a threat to our privacy. We rely on them more than the Internet to cope with modern life, yet many of us don’t believe advertisements saying we need more advanced services. Sweeping aside the doubts that many people feel about the benefits of new third generation phones and fears over the health effects of phone masts, a recent report claims that the long-term effects of new mobile technologies will be entirely positive so long as the public can be convinced to make use of them. Research about users of mobile phones reveals that the mobile has already moved beyond being a mere practical communications tool to become the backbone of modern social life, from love affairs to friendship to work.
The close relationship between user and phone is most pronounced among teenagers, the report says, who regard their mobiles as an expression of their identity. This is partly because mobiles are seen as being beyond the control of parents. But the researchers suggest that another reason may be that mobiles, especially text messaging, were seen as a way of overcoming shyness. The impact of phones, however, has been local rather than global, supporting existing friendship and networks, rather than opening users to a new broader community. Even the language of texting in one area can be incomprehensible to anybody from another area.
Among the most important benefits of using mobile phones, the report claims, will be a vastly improved mobile infrastructure, providing gains throughout the economy, and the provision of a more sophisticated location-based services for users. The report calls on government to put more effort into the delivery of services by mobile phone, with suggestion including public transport and traffic information and doctors’ text messages to remind patients of appointments. There are many possibilities. At a recent trade fair in Sweden, a mobile navigation product was launched. When the user enters a destination, a route is automatically downloaded to their mobile and presented by voices, pictures and maps as they drive. In future, these devices will also be able to plan around congestion and road works in real time. Third generation phones will also allow for remote monitoring of patients by doctors. In Britain, scientists are developing an asthma management solution using mobiles to detect early signs of an attack.
Mobile phones can be used in education. A group of teachers in Britain use third generation phones to provide fast internet service to children who live beyond the reach of terrestrial broadband services and can have no access to online information. ‘As the new generation of mobile technologies takes off, the social potential will vastly increase,’ the report argues.

The navigation product launched in Sweden is helpful for drivers because .........

Staggering tasks confronted the people of the United States, North and South when the Civil War ended. About a million and a half soldiers from both sides had to be demobilized, readjusted to civilian life, and reabsorbed by the devastated economy.
Civil government also had to be put back on a peacetime basis and interference from the military had to be stopped. The desperate plight of the South has eclipsed the fact that reconstruction had to be undertaken also in the North, though less spectacularly. Industries had to adjust to peacetime conditions; factories had to be retooled for civilian needs.
Financial problems loomed large in both the North and the South. The national debt had shot up from a modest $65 million in 1861, the year the war started, to nearly $3 billion in 1865, the year the war ended. This was a colossal sum for those days but one that a prudent government could pay. At the same time, war taxes had to be reduced to less burdensome levels.
Physical devastation caused by invading armies, chiefly in the South and border states, had to be repaired. This Herculean task was ultimately completed, but with discouraging slowness.
Other important questions needed answering. What would be the future of the four million Black people who were freed from slavery? On what basis were the Southern states to be brought back into the Union?
What of the Southern leaders, all of whom were liable to charges of treason? One of these leaders, Jefferson Davis, president of the Southern Confederacy, was the subject of an insulting popular Northern song, “Hang Jeff Davis from a Sour Apple Tree,” and even children sang it. Davis was temporarily chained in his prison cell during the early days of his two-year imprisonment. But he and the other Southern leaders were finally released, partly because it was unlikely that a jury from Virginia, a Southern Confederate state, would convict them. All the leaders were finally pardoned by President Johnson in 1868 in an effort to help reconstruction efforts proceed with as little bitterness as possible.

 It can be inferred from the passage that President Johnson pardoned the Southern leaders in order to ...........

Telecommuting-substituting the computer for the trip to the job-has been hailed as a solution to all kinds of problems related to office work. For workers, it promises freedom from the office, less time wasted in traffic, and help with child-care conflicts. For management, telecommuting helps keep high performers on board, minimizes tardiness and absenteeism by eliminating commutes, allows periods of solitude for high-concentration tasks, and provides scheduling flexibility. In some areas, such as Southern California and Seattle, Washington, local governments are encouraging companies to start telecommuting programs in order to reduce rush-hour congestion and improve air quality, but these benefits do not come easily. Making a telecommuting program work requires careful planning and an understanding of the differences between telecommuting realities and popular images.
Many workers are seduced by rosy illusions of life as a telecommuter. A computer programmer from New York City moves to the tranquil Adirondack Mountains and stays in contact with her office via computer. A manager comes into his Office three days a week and works at home the other two. An accountant stays home to care for child; she hooks up her telephone modem connections and does office work between calls to the doctor.
These are powerful images, but they are a limited reflection of reality. Telecommuting workers soon learn that it is almost impossible to concentrate on work and care for a young child at the same time. Before a certain age, young children cannot recognize, much less respect, the necessary boundaries between work and family. Additional child support is necessary if the parent is to get any work done.
Management, too, must separate the myth from the reality. Although the media has paid a great deal of attention to telecommuting, in most cases it is the employee’s situation, not the availability of technology, that precipitates a telecommuting arrangement.
That is partly why, despite the widespread press coverage, the number of companies with work-at-home programs or policy guidelines remains small.

Choose the item among A, B, c or D that best answers the question about the passage:

"The US Department of Labor statistics show that there is an oversupply of college-trained workers and that this over supply is increasing. Already there have been more than enough teachers, engineers, physicists, aerospace experts, and other specialists. Yet colleges and graduate schools continue every year to tum out highly trained people to compete for jobs that aren’t there. The result is that graduates cannot enter the profession for which they were trained and must take temporary jobs which do not require a college degree. On the other hand, there is a great need for skilled workers of all sorts: carpenters, electricians, mechanics, plumbers, and TV repairmen.
These people have more work than they can deal with, and their annual incomes are often higher than those of college graduates. The old gap that white-collar workers make a better living than blue-collar workers no longer holds true. The law of supply and demand now favors the skilled workmen.
 The reason for this situation is the traditional myth that college degree is a passport to a prosperous future. A large part of American society matcher succeeds in life equally with a college degree. Parents begin indoctrinating their children with this myth before they are out of grade school. High school teachers play their part by acting as if high school education were a preparation for college rather than for life.
 Under this pressure the kids fall in line. Whether they want to go to college or not doesn’t matter. Everybody should go to college, so of course they must go. And every year college enrollments go up and up, and more and more graduates are overeducated for the kinds of jobs available to them.
 One result of this emphasis on a college education is that many people go to college who do not belong there. Of the sixty percent of high school graduates who enter college, half of them do not graduate with their class. Many of them drop out within the first year. Some struggle on for two or three years and then give up."
