应该是A，靠

I prefer A too

会不会A选项中的context误写成了content?确信的说,第一个boldface不是结论,而是背景,客观存在的事实.由它引出了问题whether use fuel fewer和结论yes.

支持E.具体分析思路为:

原文可以这么还原一下(也就是加了一句话,即that is,不改变原文任何意思)：

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, (that is, 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), 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.

为了方便分析，再还原一下(把语句稍微调整了一下,不改变原文任何意思)，即：

(BF1)Delta products, Inc., has recently switched at least partly from older technologies using fossil fuels to new technologies powered by electricity.
                Furthormore,
                (BF2)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. Clearly, 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

我想这样的话,就可以确定选E了.

open to discuss!

当然是E啦,因为结论是能源消耗的减少，首要的条件就是你得用了新技术阿，第一句话不就是说那个公司用了新的技术吗？！ai....

哪位大哥告诉我D选项是什么意思啊？感觉和E是一个意思啊

d是说两个boldface都对结论进行了质疑，明显不对嘛。

e是说进行了支持。

you can do most boldface questions with the following 3-point procedure:
1) FIND THE CONCLUSION OF THE PASSAGE IN SIMPLE TERMS

in this case, the conclusion is "yes, delta's operations now use less fossil fuel."

2) JUDGE WHETHER THE BOLDFACE PARTS CHALLENGE, SUPPORT, OR ACTUALLY ARE THE CONCLUSION

no need to be more subtle than this, at least at first.
in this case, both boldface parts are PRO-conclusion. neither one of them actually IS the conclusion.

3) SELECT THE APPROPRIATE ANSWER CHOICE

(a) is wrong because it says boldface #1 is the conclusion.
(b) is wrong because it says boldface #2 is the conclusion.
in (c) both parts are wrong; #1 isn't anti-conclusion, and #2 isn't the conclusion.
in (d) both parts are wrong; neither #1 nor #2 is anti-conclusion.
(e) correctly points out that both #1 and #2 are pro-conclusion, but that neither is the actual conclusion.
