天山-Maths&Verbal 4-Q32 boldface题一

请教:

Delta Products, Inc., has recently switched at least partly from older technologies using fossil fuels to new technologies powered by electricity. The question has been raised whether it can be concluded that for a given level of output, Delta’s operation now causes less fossil fuel to be consumed than it did formerly. The answer, clearly, is yes, since the amount of fossil fuel used to generate the electricity needed to power the new technologies is less than the amount needed to power the older technologies, provided that the level of output is held constant.

A: The first identifies the content of the conclusion of the argument; the second provides support for that conclusion.

B: The first provides support for the conclusion of the argument; the second identifies the content of that conclusion.

C: The first states the position that the argument opposes; the second states the conclusion of the argument.

D: Each provides evidence that calls the conclusion of the argument into question.

E: Each provides support for the conclusion of the argument.

The given answer is E. I don't know why......

Thanks a lot advance.

第一个黑线我认为是premise,没这个选项,那也就可能是E了.

把所有的困苦都看做是有意义的,是生命对你的磨练,也许,是为了让你成大事而做准备。

呵呵,刚突然想起这里的推倒可能是这样的,fact=>1个结论,然后说明这个结论的正确.我想这个fact是推出结论的,那么一定也是加强结论的.有点想我们写议论文时候的事实证明.
