OG12 CR97 请教B和D的区别

97.  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 level of
output is held constant.
In the argument given, the two boldfaced portions play which of the following roles?
(A) The fi rst identifi es the content of the conclusion of the argument; the second provides support for that conclusion.
(B) The fi rst provides support for the conclusion of the argument; the second identifi es the content of that conclusion.
(C) The fi rst states the conclusion of the argument; the second calls that conclusion into question.
(D) The fi rst 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.

答案选B 请问D为什么错，其实就是对BD2的理解，D说把结论变成了问题不是也承认了BD2是结论了吗？

(D) The  rst provides support for the conclusion of the argument; the second calls that conclusion into question

楼主你好，选项D the second calls that conclusion into question的意思是说，第二部分是对之前得出的结论进行质疑。

call sth. into question: challenge the accuracy, probity, or propriety of;
"We must question your judgment in this matter"

楼上提的问题我也迷惑了
我觉得 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. 是结论
for a given level of output Delta’s operation now causes less fossil fuel to be consumed than it did formerly 是结论的内容
额。。。有点混乱了
请牛牛解答~

弱弱的问...结论和结论的内容有区别吗?
