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 36 to 42.

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 seemed 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 electricity produced in the United States each year. In 1986 such plants had a combined generating capacity of 289,000 megawatts and consumed 33 percent of the nearly 900 million tons of coal mined in the country that year. Given the uncertainty in 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 States by the end of the century.

Yet, in spite 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 United States fossil-fuel reserves), it has actually never been the most desirable fossil fuel for power plants. Coal contains 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 a purely economic perspective.

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

In the author's opinion, the importance of coal-generated electricity could increase in the future for which of the following reasons? 

A. The possible substitutes are too dangerous.

B. The cost of changing to other fuels is too great.

C. The future availability of other fuels is uncertain.

D. Other fuels present too many environmental problems.

Read the following passage and mark the letter A, B, C, D on your answer sheet to indicate the correct answer to each of the questions

Because geologists have long indicated that fossil fuels will not last indefinitely, the U.S government finally acknowledged that sooner or later other energy sources would be needed and, as a result, turned its attention to nuclear power. It was anticipated that nuclear power plants could supply electricity in such large amounts and so inexpensively that they would be integrated into an economy in which electricity would take over virtually all fuel-generating functions at nominal cost. Thus, the government subsidized the promotion of commercial nuclear power plants and authorized their construction by utility companies. In the 1960s and early 1970s, the public accepted the notion of electricity being generated by nuclear power plants in or near residential areas. By 1975, 54 plants were fully operational, supplying 11 percent of the nation’s electricity, and another 167 plants were at various stages of planning and construction. Officials estimated that by 1990 hundreds of plants would be on line, and by the turn of the century as many as 1000 plants would be in working order.

Since 1975, this outlook and this estimation have changed drastically, and many utilizes have cancelled existing orders. In some cases, construction was terminated even after billions of dollars had already been invested. After being completed and licensed at a cost of almost $6 billion, the Shoreham Power Plant on Long Island was turned over to the state of New York to be dismantled without ever having generated electric power. The reason was that residents and state authorities deemed that there was no possibility of evacuating residents from the area should an accident occur.

Just 68 of those plants under way in 1975 have been completed, and another 3 are still under construction. Therefore, it appears that in the mid1990s 124 nuclear power plants in the nation will be in operation, generating about 18 percent of the nation’s electricity, a figure that will undoubtedly decline as relatively outdated plants are shut down

How does the author describe the attitude of the population in regard to nuclear power as fuel in the early to the mid 1970s?

A. Apprehensive

B. Ambivalent

C. Receptive

D. Resentful
