<b> Delta Products Inc  has recently switched at least partly from older technologies using fossil fuels to new technologies powered by electricity  </b> The question has been raised whether it can be concluded that <b> for a given level of output Delta' s operation now causes less fossil fuel to be consumed than it did formerly </b>
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
Each provides support for the conclusion of the argument.
