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:
It is not surprising that the birthplace of cola was the hot and humid American South. This region had long specialized in creating delicious soft drinks. A druggist in Atlanta, Georgia named John Pemberton created the most well–known drink brand in the world in the 1880s. However, it seems clear that he had no idea how big it would become.
Like many American pharmacists of the day, Pemberton was opposed to the drinking of alcohol and wanted to produce a stimulating soft drink. First, he made "the French Wine of Coca," made from the coca leaf. Then he began to experiment with the cola nut. Eventually, he managed to make a combination of the two that he thought was sweet, but not too sweet. Deciding that "the two C's would look well in advertising," he named it Coca–Cola.
Pemberton's invention caught on fairly quickly. By 1905, "Coke" was being advertised all over the country as "The Great Natural Temperance Drink." The drink enjoyed additional success since there was a large and popular temperance movement in the US at that time. In the 1920s, alcohol was outlawed, and sales of Coke rose significantly. However, they continued to rise even after the law was repeated.
Another reason for Coke's popularity was good business sense. A year after he invented it, Pemberton had sold Coca–Cola to Asa Griggs Candler for only $283.26! Candler was a marketing genius, and by the time he sold the Coca–Cola Company in1919, it was worth $25 million.

Which of the following is responsible for Coke’s additional success?

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:
Life originated in the early seas less than a billion years after the Earth was formed. Yet another three billions years were to pass before the first plants and animals appeared on the continents. Life's transition from the sea to the land was perhaps as much of an evolutionary challenge as was the genesis of life.
What forms of life were able to make such a drastic change in lifestyle? The traditional view of the first terrestrial organisms is based on megafossils - relatively large specimens of essential whole plants and animals. Vascular plants, related to modern seed plants and ferns, left the first comprehensive megafossil record. Because of this, it has been commonly assumed that the sequence of terrestrialization reflected the evolution of 10 modern terrestrial ecosystems. In this view, primitive vascular plants first colonized the margins of continental waters, followed by animals that fed on the plants, and lastly by the animals that preyed on the plant-eaters. Moreover, the megafossils suggest that terrestrial life appeared and diversified explosively near the boundary between the Silurian and the Devonian periods, a little more than 400 million years ago.
Recently, however, paleontologists have been taking a closer look at sediments below this Silurian- Devonian geological boundary. It turns out that some fossils can be extracted from these sediments by putting the rock in an acid bath. The technique has uncovered new evidence from sediments that were deposited near the shores of the ancient oceans - plant microfossils and microscopic pieces of small animals. In many instances, the specimens are less than one-tenth of a millimeter in diameter. Although they were entombed in the rocks for hundreds of millions of years, many of the fossils consist of the organic remains of the organism.
These discovered fossils have not only revealed the existence ofpreviously unknown organisms, but have also pushed back these dates for the invasion of land by multicellular organisms. Our view about the nature of the early plants and animal communities are now being revised. And with those revisions come new speculations about the first terrestrial life-forms.

According to the theory that the author calls "the traditional view", what was the first form of life to appear on land?

After twenty years of growing student enrollments and economic prosperity, business schools in the United States have started to face harder times. Only Harvard’s MBA School has shown a substantial increase in enrollment in recent years. Both Princeton and Stanford have seen decreases in their enrollments. Since 1990, the number of people receiving Masters in Business Administration (MBA) degrees, has dropped about 3 percent to 75,000, and the trend of lower enrollment rates is expected to continue.
There are two factors causing this decrease in students seeking an MBA degree. The first one is that many graduates of four-year colleges are finding that an MBA degree does not guarantee a plush job on Wall Street, or in other financial districts of major American cities. Many of the entry- level management jobs are going to students graduating with Master of Arts degrees in English and the humanities as well as those holding MBA degrees. Students have asked the question, “Is an MBA degree really what I need to be best prepared for getting a good job?” The second major factor has been the cutting of American payrolls and the lower number of entry-level jobs being offered. Business needs are changing, and MBA schools are struggling to meet the new demands.

The word “prosperity” in the first paragraph could be best replaced by which of the following?

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 1826, a Frenchman named Niépce needed pictures for his business. He was not a good artist, so he invented a very simple camera. He put it in a window of his house and took a picture of his yard. That was the first photograph.
The next important date in the history of photography was 1837. That year, Daguerre, another Frenchman, took a picture of his studio. He used a new kind of camera and a different process. In his pictures, you could see everything clearly, even the smallest details. This kind of photograph was called a daguerreotype.
Soon, other people began to use Daguerre's process. Travelers brought back daguerreotypes from all around the world. People photographed famous buildings, cities, and mountains.
In about 1840, the process was improved. Then photographers could take pictures of people and moving things. The process was not simple and photographers had to carry lots of film and processing equipment. However, this did not stop photographers, especially in the United States. After 1840, daguerreotype artists were popular in most cities.
Matthew Brady was one well-known American photographer. He took many portraits of famous people. The portraits were unusual because they were lifelike and full of personality. Brady was also the first person to take pictures of a war. His 1862 Civil War pictures showed dead soldiers and ruined cities. They made the war seem more real and more terrible.
In the 1880s, new inventions began to change photography. Photographers could buy film ready- made in rolls, instead of having to make the film themselves. Also, they did not have to process the film immediately. They could bring it back to their studios and develop it later. They did not have to carry lots of equipment. And finally, the invention of the small handheld camera made photography less expensive. With a small camera, anyone could be a photographer. People began to use cameras just for fun.
They took pictures of their families, friends, and favorite places. They called these pictures "snapshots".
Documentary photographs became popular in newspapers in the 1890s. Soon magazines and books also used them. These pictures showed true events and people. They were much more real than drawings.
Some people began to think of photography as a form of art. They thought that photographycould do more than show the real world. It could also show ideas and feelings, like other art forms.

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.

   For centuries, time was measured by the position of the sun with the use of sundials. Noon was recognized when the sun was the highest in the sky, and cities would set their clock by this apparent solar time, even though some cities would often be on a slightly different time. Daylight Saving Time (DST), sometimes called summer time, was instituted to make better use of daylight. Thus, clocks are set forward one hour in the spring to move an hour of daylight from the morning to the evening and then set back one hour in the fall to return to normal daylight.

   Benjamin Franklin first conceived the idea of daylight saving during his tenure as an American delegate in Paris in 1984 and wrote about it extensively in his essay, "An Economical Project." It is said that Franklin awoke early one morning and was surprised to see the sunlight at such an hour. Always the economist, Franklin believed the practice of moving the time could save on the use of candlelight, as candles were expensive at the time.

   In England, builder William Willett (1857–1915) became a strong supporter for Daylight Saving Time upon noticing blinds of many houses were closed on an early sunny morning. Willet believed everyone, including himself, would appreciate longer hours of light in the evenings. In 1909, Sir Robert Pearce introduced a bill in the House of Commons to make it obligatory to adjust the clocks. A bill was drafted and introduced into Parliament several times but met with great opposition, mostly from farmers. Eventually, in 1925, it was decided that summer time should begin on the day following the third Saturday in April and close after the first Saturday in October.

   The U.S. Congress passed the Standard Time Act of 1918 to establish standard time and preserve and set Daylight Saving Time across the continent. This act also devised five time zones throughout the United States: Eastern, Central, Mountain, Pacific, and Alaska. The first time zone was set on "the mean astronomical time of the seventy-fifth degree of longitude west from Greenwich" (England). In 1919, this act was repealed.

   President Roosevelt established year-round Daylight Saving Time (also called War Time) from 1942–1945. However, after this period, each state adopted its own DST, which proved to be disconcerting to television and radio broadcasting and transportation. In 1966, President Lyndon Johnson created the Department of Transportation and signed the Uniform Time Act. As a result, the Department of Transportation was given the responsibility for the time laws. During the oil embargo and energy crisis of the 1970s, President Richard Nixon extended DST through the Daylight Saving Time Energy Act of 1973 to conserve energy further. This law was modified in 1986, and Daylight Saving Time was reset to begin on the first Sunday in April (to spring ahead) and end on the last Sunday in October (to fall back).

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 progressive movement was a powerful and broad-based movement of reform that had lasting effects on the American political system in the first two decades of the twentieth century. It arose in reaction to the domination of the social and political system by business interests and rampant corruption throughout the political party system during the period following the end of the Civil War in 1865. Progressivism emerged as a force during the presidency of Theodore Roosevelt, from 1901 to 1909, and reached its height in the presidential campaign of 1912. By the time the United States entered World War I in 1917, progressivism as a force had faded from the political scene. The progressive movement was focused on instigating, or initiating change in three different areas. One area that was of major interest to the progressive movement was the imposition of legal and government control over big business, which had usurped an extraordinary amount of power in the era of the wealthy industrial barons such as Rockefeller and Carnegie. A second area of interest to the progressive movement was the improvement of the social system in order to rid society of the poverty, slum housing, and exploitation of immigrant and child labor that were a part of the era. A final area of interest was the cleaning up of the political system to move political decisions back into the realm of direct democratic control and away from the corrupt backroom deals that plagued the world of politics.
Progressivism was a grassroots movement that first gained force at the local level. In cities such as Cincinnati and Cleveland, effective urban reform movements took hold, and city officials were appointed or elected to run their respective cities along nonpartisan lines and out from under the control of political parties and bosses. The progressive movement then worked its way from the local level to the state level and then on to the national level. In the state of Wisconsin, for example, "Fighting Bob" La Follette led the drive for change, first in his role as governor of the state (1901-1906) and later as the U.S. senator representing the state (1906-1925). Under his leadership, numerous reforms were instituted: state regulation of the railroads increased, policies directed at improving the lives of workers -- such as workers' compensation and unemployment insurance -- were instituted, and in the political arena, selection of party candidates was determined by direct democratic vote rather than through backroom political wrangling.

The word “instigating” in paragraph 2 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:
When living and working in another country, there are numerous things to consider apart from the more obvious ones of climate, language, religion, currency, etc. Some important considerations are less obvious. For example, do you have a pet or do you enjoy a hobby such as horse riding? Your animal or hobby may be perceived in a completely different light in another culture so it’s important to consider the significance given to specific animals in different parts of the world and general perceptions towards them.
One example which is often mentioned in popular press is the case of dogs. In some cultures, like the US or UK, dogs are loved and considered a great pet to have at home and with the family. In other cultures, such as those where Islam is the majority religion, dogs may be perceived as dirty or dangerous. Muslims treatment of dogs is still a matter of debate amongst Islamic scholars. While these animals are widely considered by many Western cultures to be „man’s best friend’, the Koran describes them as “unhygienic”. Muslims will therefore avoid touching a dog unless he can wash his hands immediately afterwards, and they will almost never keep a dog in their home.
In Iran, for instance, a cleric once denounced „the moral depravity’ of dog owners and even demanded their arrest. If you are an international assignee living and working in Saudi Arabia or another Arabic country, you should remember this when inviting Arab counterparts to your house in case you have a dog as a pet. This is just one example of how Islam and other cultural beliefs can impact on  aspects of everyday life that someone else may not even question. A Middle Eastern man might be very surprised when going to Japan, for instance, and seeing dogs being dressed and pampered like humans and carried around in baby prams!
Dogs are not the only animals which are perceived quite differently from one culture to another. In India, for example, cows are sacred and are treated with the utmost respect. Conversely in Argentina, beef is a symbol of national pride because of its tradition and the high quality of its cuts. An Indian working in Argentina who has not done his research or participated in a cross cultural training programme such as Doing Business in Argentina may be surprised at his first welcome dinner with his Argentinean counterparts where a main dish of beef would be served.
It is therefore crucial to be aware of the specific values assigned to objects or animals in different cultures to avoid faux–pas or cultural misunderstandings, particularly when living and working in another culture. Learning how people value animals and other symbols around the world is one of the numerous cultural examples discussed in Communicaid’s intercultural training courses. Understanding how your international colleagues may perceive certain animals can help you ensure you aren’t insensitive and it may even provide you with a good topic for conversation.

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:
According to sociologists, there are several different ways in which a person may become recognized as the leader of a social group in the United States. In the tamily, traditional cultural patterns confer leadership on one or both of the parents. In other cases, such as friendship groups, one or more persons may gradually emerge as leaders, although there is no formal process of selection. In larger groups, leaders are usually chosen formally through election or recruitment.
Although leaders are often thought to be people with unusual personal ubility, decades ot research have failed to produce consistent evidence that there is any category ot “natural leaders”. It seems that there is no set of personal qualities that all leaders have in common; rather, virtually any person may be recognized as a leader if the person has qualities that meet the needs ot that particular group.
Furthermore, although it is commonly supposed that social groups have a single leader, research suggests that there are typically two different leadership roles that are held by different individuals. Instrumental leadership is leadership that emphasizes the completion of tasks by a social group.
Group members look to instrumental leaders to “get things” done.” Expressive leadership, on the other hand, is leadership that emphasizes the collective well-being of a social group’s member. Expressive leaders are less concerned with the overall goals of the group than with providing emotional support to group members and attempting to minimize tension and conflict among them. Group members expect expressive leaders to maintain stable relationships within the group and provide support to individual members.
Instrumental leaders are likely to have a rather secondary relationship to other group members. They give orders and may discipline group members who inhibit attainment of the group’s goals. Expressive leaders cultivate a more personal or primary relationship to others in the group. They offer sympathy when someone experiences difficulties or is subjected to discipline, are quick to lighten a serious moment with humor, and try to resolve issues that threaten to divide the group. As the differences in these two roles suggest, expressive leaders generally receive more personal affection from group members; instrumental leaders, if they are successful in promoting group goals, may enjoy a more distant respect.

In mentioning “natural leaders” in the second paragraph, the author is making the point that

Less than a year ago marketing director, David Smith, 33 was behaving like a secet agent. He used to secretly taped all his conversations, he refused to sign his name and he would ask his secretary to check all his emails. Anything he wrote was photocopied and kept as “evidence”. But David isn’t mad, or even mildly eccertric. He suffers from ‘resposibility OCD’, one of more common form of obsessive compulsive disorder, or OCD, as it is usually known.
OCD is now recognized as the second most prevalent mental-health problem, after depression – and the number of reported cases is soaring. Experts estimate that 2% - 3% of the population suffer from the full-blown syndrome, with as many as one in five suffering from a milder form.
OCD sufferers are tortured by obsessional thoughts, such as worrying that their hands are contaminated by germs. The terrible anxiety is only relieved by performing a particular set of behaviours. Unfortunately, any sense of relief is short-lived, which is why the behaviour must be repeated again and again. OCD sufferers know their behavior is irrational, yet feel powerless to stop.
Common treatments are either antidepressants or behavioral therapy with a psychologist, but only 60% of patients show some improvement. However, a new treatment from America is bringing fresh hope to sufferers.
One of the OCD gurus and neuropsychiatrists, Jeffrey Schwartz, has designed the Four Steps program which employs meditation teachniques with the aim of teaching sufferers to manage their symptoms by themselves. “The goal is to learn to override false brain messages”, explains Schwartz.
There are different theories about what causes the disorder. Most experts recognize a genetic element that can be triggered by a stressful event. Schwartz believes that the OCD ‘worry circuit’ is a
direct result of faulty brain chemistry. ‘When someone experiences an OCD thought, one part of the brain knows quite clearly that the hand are not dirty’, explains Schwartz ‘Some part of the brain is standing apart from the symptoms, reflecting on the sheer bizarreness of it all. The objective is to harness this impartial spectator so that patients can use this healthy part of their brain to resist the compulsions.’
David Smith is delighted with the results of Schwartz’s treatment. ‘Now I can sign cheques without a problem’, he says brightly. ‘And I don’t photocopy them either. OCD used to feel like a huge stigma, but I don’t feel handicapped by it any more. You just deal with it.’

The concept of obtaining fresh water from iceberg that is towed to populated areas and arid regions of the world was once treated as a joke more appropriate to cartoons than real life. But now it is being considered quite seriously by many nations, especially since scientists have warned that the human race will outgrow its fresh water supply faster than it runs out of food. Glaciers are a possible source of fresh water that has been overlooked until recently. (A)
Three-quarters of the Earth's fresh water supply is still tied up in glacial ice, a reservoir of untapped fresh water so immense that it could sustain all the rivers of the world for 1,000 years. Floating on the oceans every year are 7,659 trillion metric tons of ice encased in 10,000 icebergs that break away from the polar ice caps, more than ninety percent of them from Antarctica. (B)
Huge glaciers that stretch over the shallow continental shelf give birth to icebergs throughout the year. Icebergs are not like sea ice, which is formed when the sea itself freezes; rather, they are formed entirely on land, breaking off when glaciers spread over the sea. As they drift away from the polar region, icebergs sometimes move mysteriously in a direction opposite to the wind, pulled by subsurface  currents. Because they melt more slowly than smaller pieces of ice, icebergs have been known to drift as far north as 35 degrees south of the equator in the Atlantic Ocean. (C)
The difficulty arises in other technical matters, such as the prevention of rapid melting in warmer climates and the funneling of fresh water to shore in great volume. But even if the icebergs lost half of their volume in towing, the water they could provide would be far cheaper than that produced by desalination, or removing salt from water. (D)

According to the author, most of the world's fresh water is to be found in     .
