KAPLAN OFFICIAL EXPLANATION(E) PrincipleEliminate an answer choice more extreme than the stimulus itself.
This Principle question has much in common with Parallel Reasoning: the correct answer will generalize the specific example in the stimulus into a broad rule. The situation in the stimulus initially sounds pretty rosy: people are leading longer and less painful lives thanks to advances in medicine. But better health is having an adverse effect, since a greater percentage of older people in the population means that some welfare programs are now facing severe financial troubles. If we take this situation and broaden it, the author is basically saying that eliminating certain problems (shorter, more painful lives) causes others (compromised finances for social welfare programs) to arise.
(E) paraphrases that idea nicely.
(A) The author’s point is that modern medical innovations have solved some problems but created others. That’s quite different from saying that technological innovation cannot solve all problems; perhaps the new problems created by advances in modern medicine can be solved by other scientific means.
(B) contains a recommendation. The author never discusses ways to avoid the new problems created by advances in medicine; the whole point of the stimulus is that those problems have been created.
(C), (D) Answer choices that use extreme language are rarely correct. So
(C), which says that every enhancement of the quality of life has side effects, and
(D), which says that a preoccupation with prolonging life affects all social institutions, need to be eliminated. The stimulus is not that far-reaching.
