Professor Harper’s ideas...!!!

by killer1387 » Sun Mar 04, 2012 11:33 pm
Q.
Jane: Professor Harper'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 guitar's sound.

Mark: What's more, Harper'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 Jane's argument and Mark's argument?

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

I could not reach a consensus for this question. guys try out OA after some discussions, got stuck between D and E

I think the answer is E.

A. Mark's argument shows how a weakness in Jane's argument can be overcome.
Mark support Jane. Notice the word Mark' s words What's more

B. Mark’s argument has a premise in common with Jane's argument.
Mark and Jane have no common premise.

C. Mark and Jane use similar techniques to argue for different conclusions.
Mark and Jane conclusion is same i.e. Professor Harper’s ideas are of no value.

D. Mark’s argument restates Jane’s argument in other terms.
Argument comprise of premises and conclusion. Mark restates Jane conclusion but does not restates any of the Jane's premises.

E. Mark’s argument and Jane’s argument are based on conflicting suppositions.
This is the answer.
Mark says merits of Guitar sound cannot be evaluated, but John says that Torres design improved tonal/sound quality. This is conflicting. If we cannot evaluate sound then we cannot conclude sound quality improved.

Conclusion is the same but the option speaks about the argument, which includes both premises and conclusion.

IMO E.
