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c
是怎么推理出来的？？？

A 看到SOME就不对了，选项的意思是一些企业增长所以全行业增产，没有上下文逻辑关系。

B。无关选项，技术和本题无关

C 看到先放着，逻辑其实不严密，可能是干扰项，但也可能对。

D。欧洲人能占领市场，并且欧洲政府开始带头，只会使美国人情况更糟，减产。

E。减产选项

回头看C，美国人也要占领其市场，我认为不严密的地方是和EUROPEAN没有直接关系，但是由于是SUPPORT题，不需要充分，只要支持到即可，所以选C。
