Plant Manager: We would greatly reduce the amount of sulfur dioxide our copper-smelting plant releases into the atmosphere by using a new process. The new process requires replacing our open furnaces with closed ones and moving the copper from one furnace to the next in solid, not molten, form. However, not only is the new equipment expensive to buy and install, but the new process also costs more to run than the current process, because the copper must be reheated after it has cooled. So overall, adopting the new process will cost much but bring the company no profit.
The plant manager's argument is most vulnerable to criticism on which one of the following grounds?
A) The overall conclusion is about a net effect but is based solely on evidence about only some of the factors the contribute to the effect.
B) The support for the overall conclusion is the authority of the plant manager rathar than any independently verifiable evidence.
C) The overall conclusion reached merely repeats the evidence offered.
D) Evidence that is taken to be only probably true is used as the basis for a chain that something is definitely true.
E) Facts that are not directly relevant to the argument are treated as if they supported the overall conclusion.

The author concludes that based on all this evidence, that the net affect is no profit. Answer A states that this is solely based on the evidence (the cost associated with the new process). However, there is likely many other factors that would affect profit. [/spoiler]
