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 35 to 42.
Humans are bringing about another global-scale change in the atmosphere: the increase in what are called greenhouse gases. Like glass in a greenhouse, these gases admit the Sun's light but tend to reflect back downward the heat that is radiated from the ground below, trapping heat in the Earth's atmosphere. This process is known as the greenhouse effect. Carbon dioxide is the most significant of these gases – there is 25 percent more carbon dioxide in the atmosphere today than there was a century ago, the result of our burning coal and fuels derived from oil. Methane, nitrous oxide, and CFCs are greenhouse gases as well.
Scientists predict that increases in these gases in the atmosphere will make the Earth a warmer place. They expect a global rise in average temperature somewhere between 1.0 and 3.5 degrees Celsius in the next century. Average temperatures have in fact been rising and the years from 1987 to 1997 were the warmest years on record. Some scientists are reluctant to say that global warming has actually begun because climate naturally varies from year to year and decade to decade, and it takes many years of records to be sure of a fundamental change. There is little disagreement, though, that global warming is looming.
Global warming will have different effects in different regions. A warmed world is expected to have more extreme weather, with more rain during wet periods, longer droughts, and more powerful storms. Although the effects of future climate changes are unknown, some predict that exaggerated weather conditions may translate into better agricultural yields in areas such as the western United States, where temperature and rainfall are expected to increase, while dramatic decreases in rainfall may lead to severe droughts and plunging agricultural yields in parts of Africa, for example.
Warmer temperatures are expected to partially melt the polar ice caps, leading to a projected sea level rise of 50 centimeters by the year 2050. A sea level rise of this magnitude would flood coastal cities, force people to abandon low-lying islands, and completely inundate coastal wetlands. Diseases like malaria, which at present are primarily found in the tropics, may become more common in the regions of the globe between the tropics and the polar regions, called the temperate zones. For many of the world's plant species, and for animal species that are not easily able to shift their territories as their habitat grows warmer, climate change may bring extinction.

 Personal computers, or PCs, are an important part of our everyday lives. Many people cannot imagine life without them. One of the most important people in making these machines work is Bill Gates. Bill Gates was born in 1955 in Washington State. He grew up in a rich family. His parents sent him to a private school. There he met his business partner, Paul Allen. When they were in eighth grade, they were writing programs for business computers and making more.
In 1973, Gates was accepted at Harvard University. His parents were happy. They thought he would get over his obsession with computers and become a lawyer like his father. Two years later, Gates dropped out of Harvard to work on a computer program with his friend Allen. They worked eighteen hours a day in a dormitory room at Harvard. They were writing the program that would run one of the first personal computers. In 1975, they created a company called Microsoft to sell their product.
Allen became ill with cancer and left Microsoft in 1983. He recovered a few years later and started his own company. Meanwhile, Microsoft became a giant company. By 1990, at the age of thirty-four, Gates was the youngest billionaire in the history of the United States. He was the "King of Software". He achieved his success with a lot of hard work. For more than ten years, he worked sixteen-hour days, seven days a week. He had a dream and the will to succeed. By 1997, he was the richest man in the United States.
