标题: 请教gwd-15-32 BF题

Q32:

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.

In the argument given, the two boldface portions play which of the following roles?

The first identifies the content of the conclusion of the argument; the second provides support for that conclusion.
The first provides support for the conclusion of the argument; the second identifies the content of that conclusion.
The first states the position that the argument opposes; the second states the conclusion of the argument.
Each provides evidence that calls the conclusion of the argument into question.
Each provides support for the conclusion of the argument.

答案是E.为什么?

没有转折词，两者同向；

且The answer, clearly, is yes，作者支持；

首句陈述现象，尾句跟在since后面，均在用事实或者解释来支持结论。

所以E ：）

那本段话的结论在哪呢？我选的A。。因为我理解的identifies the content 的意思是：讲一下论述的大致内容（就是我读这个选项时，理解的是第一句讲了个背景的意思。。）

结论是这个：

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

简洁后为：
