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.

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

我选A，而答案是E，请问E能够有效的削弱2个方面么？感觉只是能对大气污染这方面进行削弱啊。

而A如果人们不愿意买新车，那么经济也没法boost，污染也没法降低啊。

请NN帮看看。

自己顶一下，又看了遍提议，A是不可能对的。

提干问，如果实行计划，哪个最削弱使得达不到目标。5个选项里E最好，其次是D了。所以只能选E了。

但是还是有个疑问，E也没有说明这个计划没有boost Torinia's economy

而提干又问：削弱both of the cited aims。

所以E也不太好，只是比较好而已。请NN指点

这个纯粹是个人拙见哈！

给我感觉这个原文的重点不是aim，而是plan，应该怎么做

而且题目不是在削弱aims，而是在削弱这个plan

而E从两个方面很全面的削弱了这个plan的计划

我第一次选A，第二次选D，看来还是有长进的。。。。起码D比A好

本人拙见

结论（手段-目的）：报废旧车买新车—经济增长，降低污染

E：报废旧车生产新车—增加污染（结论的一个方面被削弱，结论被削弱）

手段错误在忽视了一件事情的两面性，此有段一方面能够使工厂增加产量从而刺激经济，也使新车产生比旧车少的废气，但另一方面，增加产量本身会带来污染，与预期的两个目的的其中一个向左。
