The question stem, in an unusual way, tells us we’re looking for a weakener. So, we’re looking to weaken the notion that
humans can only be made happy by gratifying their higher cognitive functions, once they have become aware of those
faculties. (B) contradicts this notion. If many humans who are aware of intellectual gratification nonetheless prefer physical
pleasure, this would suggest that they can be made happy by something other than gratification of their higher cognitive
faculties, in which case the author’s conclusion would seem too hasty.
(A) suggests that some animals possess certain kinds of cognitive faculties, which does not at all conflict with the author’s
assertion that human cognitive faculties are simply on a higher level. (A) is irrelevant to the argument.
(C) says that humans need exposure to classical music early if they are to prefer it later, but so what? We don’t know
whether classical music is one of the “higher faculties” and (C) doesn’t present us with a case of a person being aware of the
higher pleasure but choosing the baser pleasure.
(D) , (E) We don’t know whether those athletes have been turned on to the higher pleasures or what pleasures they prefer
more, so (D) and (E) don’t matter. The notion of “serious athletes” as presented in these choices is too ambiguous to have
any real effect on the argument here.
