标题: 【prep47 一道削弱题，有些疑惑~~NN请进】

47.(34035-!-item-!-188;#058&007207)

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.

(D) The largest source of atmospheric pollutants in Torinia is not automobile emissions, but emissions from power plants.

(E) The manufacture and the scrapping of cars each generate significant amounts of air pollutants.

答案选E哈，应该不难理解
但是请大家认真看看题干啊，它说的是Which of the following, if true, most seriously undermines the likelihood that the planned incentives, if implemented, will achieve both of the cited aims?
但是E选项只是削弱了减少污染这一个方面，不知道是不是E不够好，只是相对其他选项正确，还是有其他解释？？
读懂题目很重要，谢谢大家帮助！~~~

顶一下~

谢谢大家帮助，我也有同问，并没有说明经济没有增长
同时我觉得D选项也说明了这个问题，也削弱了，并且说明工厂的污染更严重。

同问D呀

D的内容和原文不一致。
原文：Automobile emissions are a significant source of air pollutants,
D选项： The largest source of atmospheric pollutants in Torinia is not automobile emissions, but emissions from power plants

只要削弱了两个aims中的一个，也已经达到了目的。因为问的是Which of the following, if true, most seriously undermines the likelihood that the planned incentives, if implemented, will achieve both of the cited aims，而不是问undermine the likelihood that ... will achieve EITHER of the cited aims.

所以E已经达到了目的。

是这样 D只是说 power plant生产车造成污染
而 E 说生产和scrap车都会造成污染比D削弱力更强
