Steve Cooper, senior sales officer, has trained many top salespeople in this company, including 14 who have become the top salespersons in their regions and 3 who have won the top salesperson award. Although there is an art to selling, Mr. Cooper’s success at training top salespeople shows that the skills required to become a top salesperson can be both taught and learned.The argument depends on which one of the following assumptions?The argument says that because Mr. Cooper trained many people who later became top salespeople, this shows that top-level sales skills can be taught and learned.
The key assumption is that at least some of those people became top salespeople because of what he taught, not because they were already top-level before the training.
Without that link, the conclusion does not follow.
(A) Mr. Cooper does not teach the hard-sell method. Nor does he teach the I’ll-be-yourpal method. Instead, he stresses the professional-client relationship.
This is not required. The argument does not depend on which method he teaches.
(B) More than 50% of the people trained by Mr. Cooper went on to become successful salespeople.
This is not necessary. The argument only needs some evidence that his training helped produce top salespeople, not a majority success rate.
(C) One of the successful salespeople who trained under Mr. Cooper was not an accomplished salesperson before learning the Cooper Method.
This is required. If at least one successful trainee was not already accomplished before the training, then the example can support the idea that important sales skills were taught and learned. Without something like this, the trainees may simply have already had the needed skills.
(D) There is a large and expanding industry dedicated to training salespeople.
This is irrelevant. The size of the training industry says nothing about whether top sales skills can actually be taught.
(E) There is no one method with which to approach sales; a method that works for one person may not for another person.
This is not needed. The conclusion is only that the skills can be taught and learned, not that there is only one way to teach them.
Answer: (C)
