求助讨论CR prep13题

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

答案选的是C，可是我觉得应该接E，讨论的不是美国本身solar市场么？请教大家了，谢谢先

这个好象是相似性的逻辑问题,正因为美国制造商能够把产品在美国市场做成功的话,,,那么...BLA BLA

答案C说:就像欧洲那些制造商一样获得了在当地的竞争优势,所以美国也该如此.

如果你把C否掉的话，会对结论产生严重weaken。C的反面就是欧洲厂家在美国也有竞争优势，所以即使美国资助本国市场，美国厂家还是拿不到market share，所以他们也就没必要维持产量。

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 __________.

世界上大多数solar-power generators由美国生产，并且产品主要销往欧洲。但是欧洲技术跟进，占据了欧洲的国内市场，因此美国采取措施促进国内使用solar-power generators以保持其较高的生产量。

文章推理：激励国内使用就可以保证较高的生产量，填空出要加强或者解释

(A) some United States manufacturers have been substantially increasing their output over the last several years

如果加大了出口就不需要国内的销售了，和前提就无关了

(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

和solar-power generators本身的效率无关，现在讨论利用国内销量吸收因为欧洲技术突破导致欧洲销量下降的那部分产品

(C) just as European manufacturers enjoy certain competitive advantages in Europe, so do United States manufacturers in the United States

正确，之前美国的产品主要外销，但是欧洲自己的产品在自己辖区内占优势，同样美国产品在美国也就占优势，因此鼓励国内的使用可以保持销量

前面所说的if these initiatives succeed....maintain significant production levels 才会成立，因为如果美国公司在美国没有competitive advantages的话，就算solar power generators在美国的需求很大，美国公司没准也会被欧洲公司打败

(D) European governments are currently undertaking initiatives to stimulate the use of solar power within Europe

只说了欧洲没有说美国

(E) the current market for solar-power generators in the United States is very limited

市场限制只能说明在美国没有空间，所以措施无效，产量会降低
