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

为什么选C？B好像也很有道理啊？求XDJMs解释

如果你只是纠结于B和C的话 我个人的意见是 B选项是非常明显的无关选项 因为题目从未谈及‘efficiency’的事情

这道题我也做错了，纠结于E选项。我理解全文的意思是：因为欧洲公司在欧洲市场具有很好的优势，美国公司不得不回本土发展。政府就想通过激发本土人们对太阳能的需求来保证美国公司的产量。我认为要保证成功，有两个条件需要满足：1、美国本土的太阳能的市场尚未饱和，如果饱和了，就算怎么激发也没有用，2、美国市场没有其他国家的来抢。所以E和C都应该对。最终选了E，现在也没有想通C，求大侠指引正途。

我的看法是题干已经提到If these initiatives succeed in increasing the demand for solar-power generators in the United States，也就是说结论的前提是已经成功提高了美国市场需求，E选项其实是在重复题干的信息，因为SDCAR2010说过keep in mind that the auther will NOT repeat whatever is already stated in the stimulus。
