Several industries have recently switched at least partly from older technologies powered by fossil fuels to new technologies powered by electricity. It is thus evident that less fossil fuel is being used as a result of 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?

67. Several industries have recently switched at least partly from older technologies powered by fossil fuels to new
technologies powered by electricity. It is thus evident that less fossil fuel is being used as a result of 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.

请问B跟E有什么不同啊?不是一样的意思么?

答案是E

多谢各位大牛!
