Choice B is incorrect since finding the source of the cost savings in the trial shows that the savings were no mere accident and so reinforces the managers' conclusion.
Choices D and E are incorrect since by emphasizing that certain aspects of the product — its design and raw materials — were the same in the standard process and the new process, these two answer choices support, rather than cast doubt on, the conclusion that the process itself produced the savings. Passengers must exit airplanes swiftly after accidents, since gases released following accidents are toxic to humans and often explode soon after being released.

Question: Which of the following, if true, casts most doubt on the production managers' conclusion? In the cost reduction project that eventually led to the trial of the new process, production managers had initially been seeking cost reductions of fifty percent. Analysis of the trial of the new process showed that the cost reduction during the trial was entirely attributable to a reduction in the number of finished products rejected by quality control. While the trial was being conducted, production costs at the factory for a similar product, produced without benefit of the new process, also showed a fifteen percent reduction. Although some of the factory's managers have been arguing that the product is outdated and ought to be redesigned, the use of the new production process does not involve any changes in the finished product. Since the new process differs from the standard process only in the way in which the stages of production are organized and ordered, the cost of the materials used in the product is the same in both processes.
Answer: C Answer Explanation: The managers concluded that the new process produced a cost savings on the basis of a trial run of the process in which costs were 15 percent lower than they had been previously.
Choice A says that the hoods would delay passengers and is thus the best answer.
If some airlines are unwilling to buy the hoods, it might be necessary to require them to, so B is incorrect.
