T-4-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 context 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 conclusion of the argument.

我选的是E，可是答案是A
为什么捏？

OG12中有类似的题，黑体的位置不大一样：

In the argument given, the two boldfaced 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 conclusion of the argument; the second calls that conclusion into question.
(D) The first provides support for the conclusion of the argument; the second calls that conclusion into question.
(E) Each provides support for the conclusion of the argument.
答案是B
它的resoning是：
What roles do the two boldfaced portions play in the argument? The first boldfaced statement is simply asserted by the passage. But the second boldfaced statement, when it is first introduced, is not asserted to be true, but rather is identified as something that might be inferred from the first statement. By the end of the passage the argument concludes that the second statement is true.
说A错是因为This option simply reverses the roles that the statements play in the argument.     那么第一个boldface就该是support了啊。
那为什么T-4-Q32中，它又成context of conclusion了呢？(ps:context是什么意思呢，是指“相对应的上下文”吗？)
呼叫NN和好心人帮忙！

T-4-Q32中context表示这个结论所产生的背景,更合适

这样的话，我可以理解为什么A是对的，但是根据OG，E也应该是对的啊，那为什么不能选E呢？

og12中的选项a说的是：content。事实上是context而不是content。也不是support。

我认为是E，是content不是context

答案是E
Nice one! Bold faced questions are needed, as they are becoming increasingly frequent on the real test and there aren't many practice questions out there!

To answer to this question, the first step is to identify the conclusion. You may think that ALL the last sentence is the conclusion, but this would be wrong. The conclusion is simplly "the answer is yes". The first bold and the second bold parts try to reinforce this conclusion, the former by stating a fact necessary to introduce the argument and the latter by counter-argumenting an opposition that could be raised against the author's argument.
Hence, answer is E.

安非它名

ppt里原题A是用context而不是content，但觉得AE都对

安非它名

题目中的conclusion是说新采用的设备可以降低成本，第一个bold其实是这个conclusion的背景而不是支持（正是有了第一个bold，才导致了可否降低成本一说），而第二个bold没争议是支持，所以答案不是E，而是A

jczephyr

第一个bold最精确的说法应该是提供了context，说这个context起到对结论的support可以接受，但不是最佳说法。

引用sdcar2010大侠的发言……
"supply a context" is neutral,neither supporting nor weakening. It's the same as background.
