标题: PREP1-47

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.

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。

请问如和排除D选项呢？？

作者: babee2queen 时间: 2009-4-24 18:47
即使说了power plant 是largest pollutant source，也不能证明实行了plan不会刺激经济并且不会减少污染。是个无关选项

还是没明白，E到底怎么就削弱boost economy这个方面了啊！！！！！！！！！！！！！
求求求！！！！！！！！！！！！

没人来啊！！！！！！！！！呼唤高手！！！！！！！！

来个比较具体的分析吧，反正在吃饭没什么事情。
E: 换车的过程和生产的过程会产生pollution。这个plan满足了boost econ, 因为换车本身就是旧车的车主在买新车；但plan违背了减少污染。所以不能achieve both aims. 这个选项削弱了环保

D: 楼上有人说的没错，就是即使car emission占总的污染额不大，但不能就此ingorecar emission。

选D的时候心里想的是，工厂的排放是首要的污染源，那么刺激旧车换新车也就刺激了制造，结果就使得工厂排放出了更多的污染了，所以不能达到减少排放的目的了，和E其实基本上是一样的效果，而且这里说的是最主要的污染就是排放，刺激生产产生的污染应该是比减少汽车的排放量还要大啊

LZ看看这样理解可以不？

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

这句问题应该不是说选项一定要同时削弱两个aims，而是削弱同时达到两个aims的可能性，即是说，把both aims看成一个整体，削弱对象是可能性。那么，只要削弱哪怕是其一，也是削弱了总体可能性。

毕竟这句话的宾语是likelihood。

LZ，题目most seriously undermines the likelihood that the planned incentives, if implemented, will achieve both of the cited aims? 的意思是，哪个为真，会削弱一个可能性，什么可能性？同时达到俩全的可能性。就是说只要削弱了其中1个，就是削弱了这种两全其美的可能性了！

作者: dreamistrue 时间: 2012-5-12 07:17
D不选是因为又扯到了power plant ，这是题目中没有出现的。(D) The largest source of atmospheric pollutants in Torinia is not automobile emissions, but emissions from power plants. T最大的污染源不是来自汽车尾气，而是来自power plant, 这个D和题目中的要否定boost economy和reduce air pollution一点关系也木有啊！

那E选项是如何削弱的呢，顶多削弱降低污染，可是增加经济呢？

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

If this happens, the aim of lessening the air pollution wont be satisfied as significant amount of air pollution is caused in both old cars as well as manufacturing of new cars and scrapping of old cars. The argument states as premise that
"cars over five years old typically generate significantly greater amounts of pollutants than newer cars". But if the procedure in this transition leads to same amount of pollution, why will people even think of changing their cars even if there are incentives. They are not going to receive the cars for free. These are just incentives. Since government expects that people can help in reducing pollution, they provide incentives. And if new cars are not purchased then there is no point boost in economy.

Answer is E.

Both the aims should be achieved, but here one aim depends on other and hence the primary aim is reducing air pollution as supplemented by the premise. This is the most suitable option.
