24. (E)
Question Type: Strengthen the Conclusion
The sociologist implies that evil people join institutions, thereby making the institutions themselves evil. So, evil people come first, and then evil institutions follow. This argument would break down if we learned that the nature of the institution actually determines the characteristics of those who join it. Answer (E) strengthens the argument by striking down this possibility.
(A) discusses doing good and evil, but the issue is really whether the people themselves are evil to begin with.
(B) is a detail distortion (from good and evil to perfect and imperfect).
(C) is out scope (the issue is not whether people should or shouldn’t be optimistic, but rather whether people are inherently evil).
(D) fails to get at the issue: do inherently evil people make institutions evil or do institutions make people evil?
