标题: 天山 4-32 （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?

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.

答案是E，但我认为正确答案应该是A

理由如下：

Delta products, Inc., has recently switched at least partly from older technologies using fossil fuels to new technologies powered by electricity.

这句话里及没论据且与下面要回答的问题（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. ）联系并不是很紧密，仅仅是提供了一个问题讨论的大环境，既上下文的联系。而且，正因为是有了这个大的CONTENT，下面才提出了这个问题需要回答。

一般来说对SUPPORT取非应该是WEAKEN那个要回答的问题，但如果对第一句取非，整个题目所赖已存在的基础就都没有了，不但问题问不出来，第二部分提出的SUPPORT也没有了意义。

突然一点想法，大家再讨论！

这道题的CONCLUSION 是指 Delta's operation now causes less fossi fuel to be consumed than it did formely吗？如果是，那么E就是正确答案。我今天作了这套体，也选了A, 但仔细想想，也许是CONCLUSION没有看对，大家能否讨论一下？多谢
