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

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.

答案是E ,E 我怎么看不懂啊？

哪位大侠帮帮我？

B 为什么不对呢？ 支持减轻污染，但说明在别地造，那么就不能兼顾经济了

版主，帮帮我吧！

B  这个PLANT制造的车比其他地方制造的同SIZE的车释放的污染少，这样每五年一次换车刺激经济。换完车后又真真正正减少污染

E scrap 和manufacture都产生污染  即使每五年一次换车刺激了经济，但减少污染的目的并没达到，所以两个目的没有同时实现，不就是题目要的答案吗

小妹妹这个题目是这样的,原文说的是如果政府用一个政策:要求超过5年的车被替换,那么就会达到目的1,减少污染2刺激经济.

B说在T这个地方生产的车比别的地方生产的同型号的车排放的污染要少.这个是无关选项.原文只说由于5年以后汽车排放的污染大了所以要改进,没有和其他地方比过.

E说生产车会产生很大的污染.这个不是削弱了吗?什么都不用往里加.就说明了污染不会减少
