这道题怎么都想不明白。
希望大家帮我解答一下！！！谢谢！！！
67. Several industries have recently switched at least partly from older technologies powered by fossil fuels to new technologies powered by electricity. It is thus evident that less fossil fuel is being used as a result of the operations of these industries than would have been used if these industries had retained their older technologies.

Which of the following, if true, most strengthens the argument above?
(A) Many of the industries that have switched at least partly to the new technologies have increased their output.
(B) Less fossil fuel was used to manufacture the machinery employed in the new technologies than was originally used to manufacture the machinery employed in the older technologies.
(C) More electricity is used by those industries that have switched at least partly to the new technologies than by those industries that have not switched.
(D) Some of the industries that have switched at least partly to the new technologies still use primarily technologies that are powered by fossil fuels.
(E) The amount of fossil fuel used to generate the electricity needed to power the new technologies is less than the amount that would have been used to power the older technologies.

请问这个B为什么不对。OG上的解释实在不太明白。
manufacture the machinery in the technology 不能看做是operation 的一部分么？？？？

我对B项是这么理解的，B项说制造机器比以前用的燃料少了，而题目中的意思是使用新机器比使用旧机器消耗的能源少，应该指的是用这些机器制造东西而不是制造这些机器，这样的话，B项与内容相符程度小，不能支持。

B项说制造机器比以前用的燃料少。
题干中没有提到过manufacture the machinery 的事情，所以感觉应该是无关的吧。
这个题我也做错了~~选的A=.=后来发现其实A和C是一样的~

没看懂题TAT。。原文说technologies powered by fossil fuels..和powered by electricity，是说需要fossil fuels或者electricity去驱动吧。。但是E选项里说的是fossil fuel是用来generate electricity的。。彻底崩溃。。

引用NN的话
The conclusion of this argument focus on the fossil fuels used by "these industries", which refers to the industries that "use" the new machines rather than those that "manufacture" the new machines.
The answer B discuss industries that "manufacture" the new machines and should be considered irrelevant choice.

我对B的理解是:
B在讲生产机器用的fossil fuel的量。而stimulus讲机器消耗的fossil fuel的量。两者是不同的。
假设自己是一个决策者，要决定是否采用new技术，那么势必只会考虑机器消耗的量，就像买车考虑油耗一样。考虑采购机器也是考虑采购成本，不会根据生产用的ff量来做决策。此时应该是一个商业决策者而非环保主义者
