Critical Reasoning

Business manager: Our new product should be packaged with plastic shells manufactured using vacuum forming technologies, and not those of injection molding. The vacuum forming process requires the creation of molds that are far cheaper to manufacture than those needed for injection molding.

Engineer: The molds used in the injection molding process are forged from a beryllium-copper alloy which can withstand the cumulative damage caused by the production of 100 times more packaging shells than the materials used to make vacuum forming molds.

The engineer responds to the business manager by


A. forming an objection to the business manager's suggestion by emphasizing a flaw in the logic of that suggestion

B. highlighting an inherent flaw in the reasoning adopted by the business manager in order for the conclusion to have been formed

C. weakening the business manager's proposition with a concrete example that clearly contradicts the basis of that proposition

D. providing evidence that supports an objection to the business manager's claim by introducing a factor that indirectly undermines that claim

E. presenting data that is in complete opposition to that used by the business manager in support of the proposal
