请教Verbal Review, CR 第79题

79. Consumer health advocate: Your candy company adds caffeine to your chocolate candy bars so that each one delivers aspeci?ed amount of caffeine. Since caffeine is highly addictive, this indicates that you intend tokeepyour customers addicted.

Candy manufacturer: Our manufacturing process results inthere being less caffeine in each chocolate candybarthan in the unprocessed cacao beans from which the chocolate is made.

The candy manufacturer’s response is?awed as a refutation of the consumer health advocate’s argumentbecause it

(A) fails to address the issue of whether the level of caffeine in the candy bars sold by the manufacturer isenough to keep people addicted
(B) assumes without warrant that all unprocessed cacao beans contain auniform amount of caffeine
(C) does not specify exactly how caffeine is lost in the manufacturing process
(D) treats the consumer health advocate’s argument as though it were about each candy bar rather thanabout the manufacturer’s candy in general
(E) merely contradicts  the consumer health advocate’s conclusion without giving any reason tobelieve that the advocate’s reasoning is unsound

Argument Evaluation

Situation       A candy manufacturer is accused of adding ca?eine, an addictive substance, to its chocolate candy bars with the intent of keeping its customers addicted. The candy manufacturer responds to this accusation by saying that there is less ca?eine in each chocolate candy bar than in the unprocessed cacao beans from which the chocolate is made.

Reasoning       What is the ?aw in the candy manufacturer’s response? First
consider whether the response indeed
refutes the advocate’s charge. In actuality,
instead
of focusing on the details of the accusation—adding ca?eine to its chocolate bars to keepcustomers addicted—the manufacturer substitutes an entirely di?erent subject, the amount of ca?eine in cacao beans. The manufacturer’s response is a diversion, not an answer.

A    Correct. This statement properly identi?es
the ?aw in the response. The candy manufacturer does not answer the question
whether adding
ca?eine to candy bars is designed to make them

addictive.

B Even if the manufacturer did make this assumption, the information is not relevant to the accusation, which is not concerned with naturally occurring ca?eine in cacao beans.
C The precise amount of ca?eine lostin the manufacturing process is not at issue. D The manufacturer does not treat the health advocate’s argument this way.
E The manufacturer does not contradict the accusation, but rather avoids it.

The correct answer is A.
