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?

In the argument given, the two boldface portions play which of the following roles?
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 thecontent 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.
答案是E。我在A,E之间徘徊了很久,最终选的是A。想请问the content of the conslusion是什么意思呢,A和E的唯一区别就是这一点,想问错在哪儿呢?
The answer, clearly, is yes.. this is the conclusion of the argument precisely speaking....
both BFs serve to support the conclusion. first BF expresses a fact that the plant switches from old tech to new tech. 2nd BF clears one doubt around the conclusion and support the conclusion.

As you have said, first BF expresses a fact that the plant swithes from old tech to new tech. So the first one is just a fact. So my question is why A is not correct. Many thanks!!! 求指教啊~
the conclusion :.The answer, clearly, is yes. the content of the conclusion of the argument: 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
it 指代的条件BF1,说这个条件可否可以总结出balabala 的观点,后面说 The answer, clearly, is yes.紧接着补出了另外一个条件来加强 ,即BF2:since 巴拉巴拉,所以BF 1+ BF2 共同推出conclusion。 我应该是讲明白了呵呵~

I got your point,so the sentence “The first identifies the content of the conclusion of the argument” actually means the first is the conslusion,where the first is absolutely a fact。 Am I right this time?
