从SC角度研究T-4-32 恳请NN解答 困惑很久 想得都睡不着

CD-V-12T-4-Q32（以前有CR分析，但想从SC角度看这题）
   

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 fenerate 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?

1. The first identifies the content of the conclusion of the argument; the second provides support for that conclusion.

2. The first provides support for the conclusion of the argument; the second identifies the content of that conclusion.

3. The first states the position that the argument opposes; the second states the conclusion of the argument. ？

4. Each provides evidence that calls the conclusion of the argument into question.

5. Each provides support for conclusion of the argument.

本文正确答案E可以概括为：

1个中心（结论）；

2个基本点（支持的理由：BF1，BF2）

但想请教NN，从语法角度，分析下BF2的句子结构、含义：

the amount of fossil fuel used to fenerate 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. 

这个绿色块中的词fenerate到底是什么意思？这前半句的结构？electricity
    是new technologies     用的，是替代fossil fuel    的，这前半句把3个都放在一起，有点不明白？

我理解的是： 

the amount of the electricity needed to power the new technologies is less than the amount of fossil fuel needed to power the older technologies, provided that the level of output is held constant.

 请NN分析下，不弄明白非常痛苦，现在都凌晨1：48，睡不着，请NN一定帮忙！先谢谢了。

Fenerate    这个单词我查了几种词典都查不到。

yeah, should be "generate"...LZ should take a break and relax.

谢谢nymph，jandjshi 二位，祝你们考试顺利啊！

今天可以睡着了，呵呵！

以下为微软百科里关于Fossil Fuels的定义，帮助后来者理解吧！

Fossil Fuels, energy-rich substances that have formed from long-buried plants and microorganisms. Fossil fuels, which include petroleum, coal, and natural gas, provide most of the energy that powers modern industrial society. The gasoline that fuels our cars, the coal that powers many electrical plants, and the natural gas that heats our homes are all fossil fuels.
