C was really tempting. But, alas, the answer is D.
Sonya: Anyone who lives without constant awareness of the fragility and precariousness of human life has a mind clouded by illusion. Yet those people who are perpetually cognizant of the fragility and precariousness of human life surely taint their emotional outlook on existence.
Sonya’s statements, if true, most strongly support which one of the following?
(A) Anyone who places a higher priority on maintaining a positive emotional outlook than on dispelling illusion will be
completely unaware of the fragility and precariousness of human life. X
This takes things too far.
(B)
Either no one has a tainted emotional outlook on existence, or no one has a mind clouded by illusion. X
This contradicts the passage, which says that both types of people exist..not just one.
(C) It is impossible for anyone to live without some degree of
self-deception. X
The problem with this choice is 'self-deception'...I don't think either 'illusion' or 'emotional taintedness' necessarily means 'self-deception'.
(D) Everyone whose emotional outlook on existence is untainted has a mind clouded by illusion. CORRECT.
The sample space includes two types of people: those without constant awareness (these people are clouded by illusion) and those with constant awareness (these people have a tainted emotional outlook). So you're either one or the other.
(E) It is
better to be aware of the fragility and precariousness of human life than to have an untainted emotional outlook on existence. X
Nothing in the passage suggests that one is better than the other...perhaps they are both equally bad.
