Mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions:

The invention of the incandescent light bulb by Thomas A. Edison in 1879 created a demand for a cheap, readily available fuel with which to generate large amounts of electric power. Coal seem to fit the bill, and it fueled the earliest power stations (which were set up at the end of the nineteenth century by Edison himself). As more power plants were constructed throughout the country, the reliance on coal increased. Since the first World War, coal-fired power plants have accounted for about half of the electric produced in the United States each year. In 1986 such plants had a combined generating capacity of 289,000 megawatts and consumed 83 percent of the nearly 900 million tons of coal mined in the country that year. Given the uncertainty of the future growth of nuclear power and in the supply of oil and natural gas, coal-fired power plants could well provide up to 70 percent of the electric power in the United Stats by the end of the century.          

Yet, inspite of the fact that coal has long been a source of electricity and may remain one for many years (coal represents about 80 percent of the United States fossil-fuel reserves), it has actually never been the most desirable fossil fuel for power plants. Coal contain less energy per unit of weight than natural gas or oil; it is difficult to transport, and it is associated with a host of environmental issues, among them acid rain. Since the late 1960’s problems of emission control and waste disposal have sharply reduced the appeal of coal-fired power plants. The cost of ameliorating these environmental problems, along with the rising cost of building a facility as large and complex as a coal-fired power plant, has also made such plants less attractive from purely economic perspective.         

Change in the technological base of coal-fired power plants could restore their attractiveness, however. Whereas some of these changes are evoluntary and are intended mainly to increase the productivity of existing plants, completely new technologies for burning coal cleanly are also being developed.

The word “it” in paragraph 2 refers 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 following questions:

The rules of etiquette in American restaurants depend upon a number of factors the physical location of the restaurant, e.g., rural or urban; the type of restaurant, e.g., informal or formal; and certain standards that are more universal. In other words, some standards 5 of etiquette vary significantly while other standards apply almost anywhere. Learning the proper etiquette in a particular type of restaurant in a particular area may sometimes require instruction, but more commonly it simply requires sensitivity and experience. For example, while it is acceptable to read a magazine in a coffee shop, it is 10 inappropriate to do the same in a more luxurious setting. And, if you are eating in a very rustic setting it may be fine to tuck your napkin into your shirt, but if you are in a sophisticated urban restaurant this behavior would demonstrate a lack of manners. It is safe to say, however, that in virtually every restaurant it is unacceptable 15 to indiscriminately throw your food on the floor.
