Automobile emissions are a significant source of air pollutants, and cars over five years old typically generate significantly greater amounts of pollutants than newer cars. In Torinia, which has recently built its first automobile manufacturing plant, most cars are over five years old. Aiming to boost Torinia's economy and reduce air pollution, the government plans to introduce incentives for Torinians to scrap their old cars every five years and replace them with new ones.
Which of the following, if true, most seriously undermines the likelihood that the planned incentives, if implemented, will achieve both of the cited aims?
(A) Without the implementation of the planned incentives, most Torinians who own an old car would be unlikely to buy a new car.
(B) Torinia's automobile plant manufactures car models that typically generate smaller amounts of air pollutants than most similarly sized car models manufactured elsewhere.
(C) The new cars produced in Torinia are not likely to be exported to other countries.
(D) The largest source of atmospheric pollutants in Torinia is not automobile emissions, but emissions from power plants.
最大的空氣污染源是工廠, 不是汽車排放. 我當初選了這答案, 是因為沒看完題目就選, 真是不應該, 事實上應該是汽車排放雖不是最大, 但可能是第二第三大, 仍然可以reduce空氣污染的嚴重性, 所以不能推翻. 因此還是要把選項給看完, just in case, 我太大意了, 為了趕時間多做題. 哀
另外, 最高級, largest, other 通常都不是選項.
(E) The manufacture and the scrapping of cars each generate significant amounts of air pollutants.
