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 __________.
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
这道题最初我选的是E，后来重做的时候，在C和E纠结；
最初的思路是这样的，若在美国的initiatives成功，而且美国现在的市场又很小，那么当然可以预见有些美国工厂会维持相当的产量；
等重做的时候，就发现，最初的思路超出了原文的推理，其实美国现在的市场小，跟美国工厂会维持相当的产量，是没有直接联系的，或者是不能从原文里直接推出来的。也有可能，欧洲那些工厂后来也进入了美国，并且占领了市场绝大部分份额，那么就无法解释了。
而C则直接跟production level是挂钩的，所以看出逻辑题目，很多时候是自己想当然的多做了一步推理，且这个推理是，不能从原文中直接得到的。
