Magazine ad: Men and women who run competitively learn that at least two of their human capabilities—physical stamina and breath control—can be stretched to higher and higher levels. The vigorous conditioning runners undergo is critical to their performance. Proper conditioning can also stretch another human capability—our minds. If you rigorously condition your mind, it can also attain higher and higher levels. Stretch and stimulate your mind! Join your local Puzzlemaster Club.

This magazine ad uses which one of the following strategies in its approach?

(A) The ad relies on the results of experiments to suggest that joining a Puzzlemaster Club will have the effect of improving mental abilities.- it does not rely on any such experiment
(B) The ad ridicules people who don’t join a Puzzlemaster Club by suggesting that they don’t want to improve their minds.- Ad does not ridicule people
(C) The ad explains why becoming a member of a Puzzlemaster Club will stretch and stimulate your mind.- Ad does not explain that
(D) The ad supports or justifies its goal, i.e., that people join a Puzzlemaster Club, by carefully documenting the benefits of competitive running. - It is not justifying any goal
(E) The ad implies that because physical stamina, breath control and the mind are all human capabilities, our minds can be stretched to higher levels just as stamina and breath control can be stretched.- Correct choice

Hence, correct answer is E

A parallel comparison has been presented between Stretching : Physical capabilities VS Mind

Only (E) fits in perfectly...

(A) The ad relies on the results of experiments to suggest that joining a Puzzlemaster Club will have the effect of improving mental abilities. The ad does not quote any expirements' results. Eliminate.

(B) The ad ridicules people who don’t join a Puzzlemaster Club by suggesting that they don’t want to improve their minds. The ad does not ridicule anyone. Eliminate.

(C) The ad explains why becoming a member of a Puzzlemaster Club will stretch and stimulate your mind. While the ad does state that joining Puzzlemaster will stretch and stimulate the mind, it does not state why this is so. Eliminate.

(D) The ad supports or justifies its goal, i.e., that people join a Puzzlemaster Club, by carefully documenting the benefits of competitive running. This is an attractive choice. My problem is that the ad draws a clear link between stamina, breath control and the mind and states that they all can be stretched. This relationship is not brought out by this option. Also, the justification for joining Puzzlemaster is stretching the mind and not benefits of competitive running. However, we should hold on to this option at this point.

(E) The ad implies that because physical stamina, breath control and the mind are all human capabilities, our minds can be stretched to higher levels just as stamina and breath control can be stretched. Correct answer. This perfectly brings out the similarities drawn by the ad and fits the approach taken by the ad.

Since (E) is so much better than (D), we can eliminate option (D).

Hope this helps.
