21. Jane: Professor Harperâ€™s ideas for modifying the design of guitars are of no value because there is no general agreement among musicians as to what a guitar should sound like and, consequently, no widely accepted basis for evaluating the merits of a guitarâ€™s sound.

Mark: Whatâ€™s more, Harperâ€™s ideas have had enough time to be adopted if they really resulted in superior sound. It took only ten years for the Torres design for guitars to be almost universally adopted because of the improvement it makes in tonal quality.

Which one of the following most accurately describes the relationship between Janeâ€™s argument and Markâ€™s argument?

(A) Markâ€™s argument shows how a weakness in Janeâ€™s argument can be overcome.
(B) Markâ€™s argument has a premise in common with Janeâ€™s argument.
(C) Mark and Jane use similar techniques to argue for different conclusions.
(D) Markâ€™s argument restates Janeâ€™s argument in other terms.
(E) Markâ€™s argument and Janeâ€™s argument are based on conflicting suppositions.

I think "A".....Jane says "no widely accepted basis for evaluating the merits of a guitarâ€™s sound".....Mark makes sure that this weakness is taken care of by saying that the basis of evaluation can be "the improvement of the sound", something that Professor didn't achieve either.

(D) Markâ€™s argument restates Janeâ€™s argument in other terms.
(E) Markâ€™s argument and Janeâ€™s argument are based on conflicting suppositions.

Jane dismisses Professor Harperâ€™s ideas by citing a premise that Harperâ€™s ideas will fail because musicians do not have a general scale to evaluate whether Harper brings any good to the guitar world. Mark corroborates Janeâ€™s conclusion by citing a different premise (premise: Even though there is no common scale to evaluate Torres design, musicians finally adopted it because of the improvement in tonal quality. But, Harperâ€™s ideas lack any such breakthrough improvements).

Now, eliminate choice B (reason: Janeâ€™s premise is different from Markâ€™s), choice C (reason: both Jane and Mark reach for the same conclusion), choice D (reason: there is no restatement), choice E (reason: no conflicting suppositions). As a result, choice A is the best answer.

E?

Mark is acknowledging improvement can be made to guitar functionality, and since people adopt to improved quality there is an accepted standard.

I vote for A.

As pokranII rightly pointed out, one may counter Jane's argument by saying that concensus is not a good bench-mark to evaluate an idea/design. To cover up for it, Mark says that even without concensus,an earlier design was popular in just 10 years, which the new designer wasn't able to achieve.

WinWinMBA:

I assume OA stands for Official Answer. If so, could you please elaborate how choice E is the best answer? Also, it would be great if you could share from where this entangled question is from.

I was going with A

After seeing the OA I agree with it. It should be E.

Jane :
Premise : There is no widely accepted basis for a guitars sound.

Mark :
Conclusion :Discard Harper's ideas. (implicit, by use of "whats more" )
Premise : He has had enough time to get the ideas widely accepted. It took Torres only 10 years. (implicit) It took Harper more years.

The suppositions for Mark and Jane's conclusions seem to be different. One says there is no widely accepted , and the other says that there is.

Yes that's the exact point. Jane's argument was based on the premise that "no widely accepted basis for evaluating the merits of a guitarâ€™s sound". Mark on the other hand, while trying to support her conclusion, included an example that implied that there is widely accepted basis to evaluate the merits of a guitar's sound.
