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
问题分析：A说一些美国生产商在过去一些年增加了一些output，文章一直对未来进行了一个预期，这个选项是过去增加output，显然无关，杀。
B 说转换效率提高速度不像从前那样快了，原文根本没说过，杀
C 说就像欧洲那些生产商会有优势一样，美国生产商在本地也会有优势，方向就是说美国生产商未来还不错，和原文的预计符合，先留着
D 说欧洲政府准备刺激使用太阳能，可是即便刺激产生太阳能这个和美国生产商有增加产量有什么关系呢?显然需要发散，主观答案，杀
E 说现有美国太阳能市场还很有限，方向不对，文章说美国生产商还会维持比较高的产量，可这个说美国市场有限，方向和文章最后一句话的预计相反，杀。
