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.

机动车的释放是大气污染重要来源。5年以上的老车比新车排放更多。在T很多车都5年以上了，政府为了刺激经济同时减少大气污染，计划要求T每五年报废旧的汽车，用新的替换。

文章推理：报废旧车新车替换可以刺激经济同时减少污染能

Which of the following, if true, most seriously undermines the likelihood that the planned incentives, if implemented, will achieve both of the cited aims?不能两全

(A) Without the implementation of the planned incentives, most Torinians who own an old car would be unlikely to buy a new car.

只是说刺激了经济购买，并没有说污染问题

(B) Torinia's automobile plant manufactures car models that typically generate smaller amounts of air pollutants than most similarly sized car models manufactured elsewhere.

和其他厂商无关

(C) The new cars produced in Torinia are not likely to be exported to other countries.

和汽车出口无关

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

只是说了污染来源，并没有对计划起到作用，没有提到经济问题

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

正确，生产和报废都会产生污染，所以经济可以刺激但是污染无法避免

我在AE之间纠结，最后选了A，因为我觉得E仅仅说到污染的问题，没有提到经济问题，而A的话，如果人们不想换车，那么污染问题存在（因为旧车污染很严重），并且经济问题也很大。

不知道自己哪里想错了，各种纠结。。。
想知道大家是怎么排了A选E的？
谢谢咯！！！
