澳际SAT为大家带来了12月23日SAT官方每日一题，今日试题是Critical Reading > Sentence Completions，附带答案解析，希望对SAT备考的同学们有所帮助。
Choose the word or set of words that, when inserted in the sentence, best fits the meaning of the sentence as a whole.
In some ancient cultures, colors were considered very powerful; some societies even believed that red objects had ------- effect, restoring good health through their color alone.
(A) an enervating
(B) a callow
(C) a salutary
(D) an agile
(E) a peripheral
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.
