Several industries have recently switched at least

partly from older technologies powered by fossil fuels

to new technologies powered by electricity. lt is thus

evident that less fossil fuel is being used as a resultof

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.
我选择的答案是B，但是给的答案是E，我不大接受。尤其是“the claim would encompass even any fossil fuel that might be used to generate the electricity that..."更是思维跳跃。而B选项则是没有跳跃。
请大侠解释下。
