OFFICIAL EXPLANATION
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 byA. forming an objection to the business manager's suggestion by emphasizing a flaw in the logic of that suggestion
Incorrect.
To answer this Dialog Analysis question, first break down the business manager's argument. The first sentence is a recommendation (should) and is the conclusion. The second sentence is factual, a premise in support of that conclusion:
Premise: vacuum forming molds are cheaper than injection molding molds
=
Conclusion: packaging for the product should be made using vacuum forming
Possible Assumption: because molds are cheaper the entire operation will be cheaper
Next, break down the engineer's response:
(i) The injection molding molds can make 100 times more packaging pieces than the vacuum forming molds - data that exposes the assumption
Although the engineer reveals details that undermine the business manager's plan, he or she does not explicitly object to the manager's plan. The engineer merely provides data, not an opinion.
B. highlighting an inherent flaw in the reasoning adopted by the business manager in order for the conclusion to have been formed
Incorrect.
The business manager's reasoning is not really flawed. It is quite logical to suggest the use of a certain method because it is cheaper than another method. Therefore, any claim that the business manager's reasoning contains an inherent flaw is unfounded.
The engineer actually presents new, additional information which puts the proposal into question.
C. weakening the business manager's proposition with a concrete example that clearly contradicts the basis of that proposition
Incorrect.
The data provided in the engineer's statement is not an example of anything, but merely factual information. An example would be presenting a case of someone who used one or both types and the results.
D. providing evidence that supports an objection to the business manager's claim by introducing a factor that indirectly undermines that claim
By giving information about injection molding molds, the engineer undermines the business manager's conclusion. This data could serve as support for objecting to that conclusion.E. presenting data that is in complete opposition to that used by the business manager in support of the proposal
Incorrect.
To answer this Dialog Analysis question, first break down the business manager's argument. The first sentence is a recommendation (should) and is the conclusion. The second sentence is factual, a premise in support of that conclusion:
Premise: vacuum forming molds are cheaper than injection molding molds
=
Conclusion: packaging for the product should be made using vacuum forming
Possible Assumption: because molds are cheaper the entire operation will be cheaper
Next, break down the engineer's response:
(i) The injection molding molds can make 100 times more packaging pieces than the vacuum forming molds - data that exposes the assumption
The phrase complete opposition in this answer choice means that the premises in the arguments of both the manager and engineer oppose one another. However, the fact that the injection molds are more durable (as presented by the engineer) materials can actually support the idea that they are more expensive than vacuum forming (as presented by the business manager).
