Question ID:PT70 S1 Q11 Passage:Activist: Accidents at the Three Mile Island and Chernobyl nuclear plants have shown the dangers of nuclear power. It was earlier argued that nuclear power was necessary because fossil fuels will eventually run out. Recently, however, a technology has been developed for deriving from sewage sludge an oil that can be used to generate power. This new technology, therefore, together with the possibility of using alternative sources of energy like solar, wind, and hydroelectric power, raises the hope that we can dispense altogether with nuclear power and that we can meet our energy needs in a way that better protects the environment from harm than we do at present. Stem:Which one of the following considerations is LEAST relevant in evaluating the degree of practicability of the hope expressed by the activist above? Correct Answer Choice:BChoice A:whether the current methods of disposing of sewage sludge by dumping do environmental damage Choice B:whether the processes that are used to turn sewage into clean water and sewage sludge have been improved in recent decades Choice C:whether the cost of producing and using oil from sewage sludge would be economically sustainable Choice D:whether the burning of oil from sewage sludge would, in contrast to nuclear power production, produce gases that would have a harmful warming effect on climate worldwide Choice E:whether waste products that would be produced in deriving oil from sewage sludge and burning it would be as dangerous as those produced by the mining and use of nuclear fuel
