參考答案及解析：

1.The correct answer is C

Explanation

The sentence discusses the belief of “some ancient cultures” that colors were “very powerful.” If “some societies” believed that red objects were capable of “restoring good health” simply because they were red, it makes sense to say that those societies believed that the color red “had a salutary effect,” or could cure ailments and promote health.

2.The correct answer is B

Explanation

The phrase “is to forget” implies that the belief described in the first part of the sentence is misguided or naïve. It makes sense to argue that the assumption that reforms can “eradicate,” or eliminate, all societal evils is overly idealistic because evil is “protean,” or capable of taking on a new “shape.”

3.The correct answer is D

Explanation

A “veteran,” or seasoned, actor should be able to carry himself with “ gravitas,” or seriousness. A serious performer, in turn, is capable of playing a variety of roles with “ dignity,” or a seriousness of manner.

4.The correct answer is D

Explanation

Only “methodical study” and “revolutionary change” match the ideas of “systematic examination” and “overturned entrenched beliefs.”
