(A) opportunistic . . supports
(B) noble . . undermines
(C) bemused . . aids
(D) caustic . . neglects
(E) altruistic . . assists

答案和解析

答案：E

解析：

The structure of the sentence indicates that the statement after the colon gives an example of the idea in the first part of the sentence. If Alvin is unselfish, he likely "assists," or helps, his friends without expecting anything from them in return. And helping people without expecting anything in return is an example of being "altruistic," or unselfishly concerned with the welfare of others.
