请教OG10 111

111．  Advocates of a large-scale space-defense research project conclude that it will represent a net benefit to civilian business．They say that since government-sponsored research will have civilian applications，civilian businesses will reap the rewards of government-developed technology．

Each of the following，if true，raises a consideration arguing against the conclusion above，EXCEPT：

(A)  The development of cost-efficient manufacturing techniques is of the highest priority for civilian business and would be neglected if resources go to military projects，which d0 not emphasize cost efficiency．

(B)  Scientific and engineering talent needed by civilian business will be absorbed by the large—scale project．

(C)  Many civilian businesses will receive subcontracts to provide materials and products needed by the research project．

(D)  If government research money is devoted to the space project，it will not be available for specifically targeted needs of civilian business，where it could be more efficiently used.

(E)  The increase in taxes or government debt needed to finance the project will severely reduce the vitality of the civilian economy．

这道题目选C，但是我对于B和C这两个选项有疑问。我觉得B选项是说civillian business需要的scientific and engineering都去进行这个project了，所以civillian business应该挣到更多的钱才对啊，就应该不是削弱啊。C选项是说civillian business要提供很多东西就要浪费钱啊，就是削弱啊，为什么答案不对呢？谢谢大家。

B是指civilian businesses 需要的Scientific and engineering talent都被上面所说的a large-scale space-defense research project 大工程给招去了，没有了这些人才，civilian businesses 地发展就得不到保障啊，所以是反对题干的（赚大钱的也许是那些人才，可是服务的不是civilian businesses）

而C说这个大型研究项目会通过转包合同subcontracts 让civilian businesses 受益，所以是支持题干的（经济不是说浪费钱还是节约钱，而是考虑利润，civilian businesses 得到了合同，给这个大项目提供原材料，那么国家对这个大项目投入的钱一部分作为货款就会流入civilian businesses ）

不知道我这么解释你能明白不
