标题: prep一道逻辑题,求高手解答呀~~
13. (26741-!-item-!-188;#058&002910)
Which of the following most logically completes the argument?
United States manufacturers currently produce most of the world's solar-power generators--most of which are exported to Europe. However, European manufacturers are emerging and probably will ultimately capture much of the European market. The United States government is funding initiatives intended to encourage use of solar power within the United States. If these initiatives succeed in increasing the demand for solar-power generators in the United States, United States manufacturers will probably maintain significant production levels, since __________.
(A) some United States manufacturers have been substantially increasing their output over the last several years
(B) the efficiency of solar-power generators in converting energy from the Sun into electric power is not improving as fast as it once did
(C) just as European manufacturers enjoy certain competitive advantages in Europe, so do United States manufacturers in the United States
(D) European governments are currently undertaking initiatives to stimulate the use of solar power within Europe
(E) the current market for solar-power generators in the United States is very limited
答案是C 如果动机成功增加了美国solar-power的需求,美国制造就可以维持大量的生产水平 请NN解释下C~~~ E说市场很有限,好像也可以啊 请NN进一步解释下 谢谢~~

我刚开始也在C和E之间犹豫,后来想通了。
US刺激国内需求,但是如果US人们不买US产品,那么US的生产商还是卖不出去。E,不管现在市场是25%,还是50%,只要US市场卖美国产的货,那么生产厂商就有保证,所以跟limitation没有关系,有关的就是在美国市场是否具有竞争力。如果Euro生产厂商的产品性价比更好,美国人民买Euro的产品,那么市场再大,也没有美国厂商的份。
does this make sense?

不牛,试着做一下;
逻辑链:欧洲生产商增加并将最终占领大半的欧洲市场→美国的鼓励政策成功的情况下,美国生产商的产量依然会保持很高的水平;
分析:填空题是assumption的一种,即要在前提和结论之间架桥;美国生产商的产量增加,说明有需求;
A.一些美国生产商在从过去到现在的产量都在增加。但是将来不一定会增加,而且一些不能代表整体;
B。转化的效率与产量的增加无关;
C。欧洲在本土增加,美国也会在本土增加;说明这里的假设前提就是每个区域在自己本土都会享有很大的竞争优势;
D。说的是美国的增加,与欧洲政府的举措无关;
E.无关;这个选项的确很有迷惑项;不过看题干最后一句——如果美国的这些initiatives成功,那么依然可以保持很高的产量;如果选择E,即美国市场很有限,那么就说明他们的这些initiatives无效,违反前提;所以不对;

试做,方案推理,方案是增加美国国内需求,目的是保持高生产量,问加强,要说明方案可行,方案有效或者方案没有副作用,只有C了,C提供了一种方案可以达到目标的情况
