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 ? rst identi? es the content of the conclusion of the argument; the second provides support for that conclusion. (B) The ? rst provides support for the conclusion of the argument; the second identi? es the content of that conclusion. (C) The ? rst states the conclusion of the argument; the second calls that conclusion into question. (D) The ? 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.
