标题: 新手上路请教prep07的一道cr题，请各位NN指点
prep07 第一套

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

这道题正确答案说选C，但是我觉得E也很有道理啊，如果美国现在的市场规模已经较大了，那么就算政府的initiative成功了，也很难有足够的发展余地让生产者维持现有生产规模呀
看了一位前辈的分析，虽然能接受C好像有些道理了，但是还是觉得找不出E的错误点

，请各位NN指点一二

我的见解是。E是无关选项。
逻辑链：欧洲开发自己的市场成功了，美国同样开发自己的市场，也可以获利。
E选项说美国本土市场很小，没有任何信息说美国是否可以获利。无关。
且换句话说，如果市场小，不可知美国开发自己的市场后是否可以弥补它在欧洲市场的收益，一样不可以maintain level。weaken。

open to discusion。。。

E选 ...

我觉得这个逻辑链说的是：
因：美国成功的增加了国内需求
果：生产者能够维持现有生产
我总觉得C是美国发起的对策能够成功的条件（也就是说，美国在本土有竞争优势，所以我们可以相信它的这一政策可以成功），但是和逻辑链没有什么关系。
是我的逻辑链提取出问题了吗？

楼上说的对，
因为欧洲有本土市场竞争优势，
如果美国也有，则美国会保持生产水平
