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 economic expansion prompted by the Second World War triggered a spectacular population boom in the West. Of course, the region was no stranger to population booms. Throughout much of its history, western settlement had been characterized by spurts, rather than by a pattern of gradual and steady population growth, beginning with the gold and silver rushes of the 1850's and 1860's. The decade after the First World War - the 1920's - witnessed another major surge of people pouring into the West, particularly into urban areas. But the economic depression of the 1930's brought this expansion to a halt; some of the more sparsely settled parts of the region actually lost population as migrants sought work in more heavily industrialized areas. By 1941 when the United States entered the Second World War and began to mobilize, new job opportunities were created in the western part of the nation.

If the expansion of industries, such as shipbuilding and aircraft manufacturing, was most striking on the pacific coast, it also affected interior cities like Denver, Phoenix, and Salt Lake City. Equally dramatic were the effects of the establishment of aluminum plants in Oregon and Washington and the burgeoning steel industry in Utah and California. The flow of people into these areas provided an enormous impetus to the expansion of the service industries - banks, health care services and schools. Although strained to the limit by the influx of newcomers, western communities welcomed the vast reservoir of new job opportunities. At the same time, the unprecedented expansion of government installations in the West, such as military bases, created thousands of new civilian openings. As land had served as a magnet for western migrants in the late nineteenth century, so wartime mobilization set in motion another major expansion of population. Indeed, it could be said that the entire western United States became a giant boomtown during the Second World War. This was especially true of California. Of the more than eight million people who moved into the West in the decade after 1940, almost one-half went to the Pacific coast. In fact, between 1940 and 1950, California's population surged by more than three million people.

There are three valid arguments to support the preservation of endangered species. Aesthetic justification contends that biodiversity contributes to the quality of life because many of the endangered plants and animals are particularly appreciated for their unique physical beauty. The aesthetic role of nature in all its diverse forms is reflected in the art and literature of every culture attaining symbolic status in the spiritual life of many groups. According to the proponents of the aesthetic argument, people need nature in all its diverse and beautiful forms as part of the experience of the world. Another argument that has been put forward, especially by groups in the medical and pharmacological fields, is that of ecological self-interest. By preserving all species, we retain a balance of nature that is ultimately beneficial to humankind. Recent research on global ecosystems has been cited as evidence that every species contributes important or even essential functions that may be necessary to the survival of our own species. Some advocates of the ecological argument contend that important chemical compounds derived from rare plants may contain the key to a cure for one of the diseases currently threatening human beings. If we do not protect other species, then they cannot protect us. Apart from human advantage in both the aesthetic and ecological arguments, the proponents of a moral justification contend that all species have the right to exist, a viewpoint stated in the United Nations World Charter for Nature, created in 1982. Furthermore, if humankind views itself as the stewards of all the creatures on Earth, then it is incumbent upon human beings to protect them, and to ensure the continued existence of all species. Moral justification has been extended by a movement called “deep ecology,” the members of which rank the biosphere higher than people because the continuation of life depends on this larger perspective. To carry their argument to its logical conclusion, all choices must be made for the biosphere, not for people.

Are Human Beings Getting Smarter?
Do you think you are smarter than your parents or grandparents? According to James Flynn, a professor at a New Zealand university, you might be. Over the course of the last century, IQ test scores of people in some countries have got increasingly better - on average, three points better for every decade that has passed. This trend of improving scores is known as “the Flynn effect,” and scientists want to know what is behind it. IQ tests and other similar tests are designed to measure general intelligence rather than knowledge. Flynn knew that intelligence is partly inherited from our parents and partly the result of our environment and experiences, but the improvement in test scores was happening too quickly to be explained by heredity. So what happened in the 20th century that led to higher test scores? Scientists have proposed several explanations for the Flynn effect. Some suggest that the improved test scores simply reflect an increased exposure to tests in general. Because we take so many tests, we learn test-taking techniques that help us perform better. Others have pointed to better nutrition, which results in babies being born larger, healthier, and with more brain development than in the past. Another possible explanation is a change in educational styles - children are encouraged to discover things for themselves rather than just memorizing information. This could prepare people to do the kind of problem-solving that intelligence tests require. Flynn himself suggested that learning new technologies may have improved people’s problem-solving skills. This may be true for the first decade of his tests, when IQ scores in many countries increased. However, in recent years, IQ test scores in some countries have begun to decline. Data from Norway, the Netherlands, Australia, and Great Britain have shown that as these countries become more and more modern, IQ scores have begun to drop. While scientists aren’t sure what is causing this decline, they think technology is dramatically changing the way that we learn and get information. For example, people are now able to access all kinds of information easily using online resources like Google or Wikipedia. The danger is when they start to rely too much on these sources of information, and not do any thinking for themselves. Lifestyle changes that come with modem technology may also have a negative effect on intelligence, such as video games and television making people less social.  So while the world may have got smarter over the 20th century, improving technology and changing lifestyles may soon reverse that trend.

The word “exposure” in paragraph 3 is closest in meaning to ____

Space Debris
Once something is considered rubbish, we want to throw it away and forget about it. Yet if we are not careful about where we store it, our garbage could come back to haunt us. On the Earth, poorly discarded garbage can cause land, water, and air pollution. And now, people are starting to learn that space debris can also cause a host of different problems. Space debris is defined as a collection of objects that orbit the Earth. Space debris can be classified into two categories. One is man-made rubbish, such as old satellites, rockets, and other machinery left in space after past missions. The other is natural objects, such as meteors that are traveling through space. If you think the man-made garbage doesn’t amount to much, guess again. Researchers estimate that there are over 20,000 pieces of large debris floating around in space and approximately 300,000 smaller pieces in orbit as well. Traveling at speeds of up to 17,500 miles per hour, these objects create a great degree of danger for any spaceships when they leave or return to the Earth. We are lucky to some degree that there haven’t been too many accidents caused by space debris as of yet. Still some incidents have occurred. In 1996, a French satellite was damaged after it crashed into debris from an old French rocket. Then in 2009, an old Russian satellite collided with a working US satellite. The end result was an additional 2,000 pieces of space junk that was added to the junk pile. As the current situation can only worsen, it is now up to the international community to cooperate and create a plan to deal with space debris. For starters, several nations have pledged to take more care with the items they discard in space to cut down on future debris. Researchers are working on devising a way to label space junk, so it can be avoided. Others have proposed more creative techniques to recapture the garbage and discard it on the Earth, or destroy it with lasers. The nightmare scenario that everyone fears is if the Kessler Syndrome starts to occur. This is when the density of garbage becomes so high that it sets off a chain reaction of collisions which would raise the probability of accidents even further. Although there is not a long-term solution in place for space debris, nations are starting to understand the seriousness of this problem.

The Great Debate over GM Foods
One of the hottest topic in agriculture today is genetically modified (GM) foods. GM foods are foods that come from plants that have had their DNA altered using biotechnology. GM foods have been on the market since 1994, when a company called Calgene started selling GM tomatoes. Since then, other GM foods including papaya, corn, and plums to name a few have been developed. The main benefit of GM foods is that they can be a more economical solution than non GM foods. Scientists found a way to modify many plants to make them more resistant to weeds, diseases, and pests. This allows the plants to grow in tougher climates and conditions, which should lead to lower food prices and increase the overall food supply. However, many consumers still have their doubts about GM foods. For one they feel that by eating GM foods people are messing with nature. Until now humans have survived on food that was produced without any interference from science. Even though many lab studies show that GM foods are safe in the short term, opponents feel that not enough long-term testing has been done yet. Another major issue in the GM foods debate is its labelling. Current US laws do not require producers to label their foods as GM. This has upset many consumers who feel they have the right to clearly know how the food they are buying is produced. On the other hand, producers are afraid to label their foods as GM because they feel it will result in less product sales, as people may assume that there is something wrong with GM foods. This controversy is not just on the level of consumers and producers. The issue of non GM foods has also become a block to a major free trade agreement between the US and Europe. GM foods are banned throughout most of Europe, while they are quite common throughout the US. Since many American GM food producers would like to sell their foods overseas in Europe, the US is requesting that European nations eliminate laws banning GM foods. However, many European nations are not fully convinced that these products are safe.

Read the following passage and choose the best answer (A, B, C, D):
Genetics is the study of hereditary characteristics that are passed down from one generation of living organisms to another. Although farmers have used selective breeding to improve the resilience of crops and animals, it wasn't until the mid-1800s that Gregor Mendel started the science of genetics as we know it today. Following Mendel's methods, scientists have discovered "chromosomes" and "DNA". With the ability to study DNA, scientists were able to study the genetic differences between races. Modern genetics discovered that all humans are descendants of "Mitochondrial Eve," a woman who lived over 150,000 generations have passed, and many subtle differences are now evident. Humans share at least 99% of their genetic makeup. A 1% difference may not seem like much, but when you consider that a chimpanzee shares 98% of human genes, you realize how much a 1% difference makes! Africans are more closely related to Europeans than any other two groups despite the fact that they differ so much in appearance. The biggest genetic differences are found between Africans and the native populations of Nord America (22%). However, it is essential to note that the genetic differences between people of the same race are much greater than the differences between people of different races. This means that the argument which claims that genets differences make one race superior to another is nothing but a tall story. The differences in various populations may also be the result of circumstances rather than genetic makeup. Factors such as climate, diet, health care, education, and employment as well as other socioeconomic factors are all influential. However, there are some traits which are genetic, for example, then is a much higher incidence of sickle cell anemia among black populations that any other population group. Adult African-Americans and Latinos have twice as many cases of diabetes than Caucasians. In the U.S, Latinos suffer more deaths from liver disease than other races. Europeans suffer more from heart disease and cancer. Genes not only affect our susceptibility to disease, they also affect our physical attributes. The Dinka people from the Sudan are considered to be the tallest people with men having an average height of 6ft 3 in, while women hit the big time with an impressive 5ft 3 in. This contrasts sharply with the Pygmy tribes who get the short end of the stick at only about 4ft 11 in tall. Genetic differences may help US to tailor health service to people of different races or to detect life threatening diseases early. However, they are not significant enough to support the claim that one race is superior to another. In fact, our modern scientific understanding of human genetic diversity flit in the face of almost all our social stereotypes.

Read the following passage and choose the best answer (A, B, C, D):
During the nineteenth century, women in the United States organized and participated in a large number of reform movements, including movements to reorganize the prison system, improve education, ban the sale of alcohol, and, most importantly, free the slaves. Some women saw similarities in the social status of women and slaves. Women like Elizabeth Cady Stanton and Lucy Stone were feminists and abolitionists who supported the rights of both women and blacks. A number of male abolitionists, including William Lloyd Garrison and Wendell Philips, also supported the rights of women to speak and participate equally with men in antislavery activities. Probably more than any other movement, abolitionism offered women a previously denied entry into politics. They became involved primarily in 20 order to better their living conditions and the conditions of others. When the Civil War ended in 1865, the Fourteenth and Fifteenth Amendments to the Constitution adopted in 1868 and 25 1870 granted citizenship and suffrage to blacks but not to women. Discouraged but resolved, feminists influenced more and more women to demand the right to vote. In 1869, the Wyoming Territory had yielded 30to demands by feminists, but eastern states resisted more stubbornly than before. A women's suffrage bill had been presented to every Congress since 1878 but it continually failed to pass until 1920, 35 when the Nineteenth Amendment granted women the right to vote.
