问题 A recent study suggests that vitamin E supplements, despite widespread belief in their______, are no better than sugar pills for delaying the onset of the degenerative disease.
A potential
B misuse
C popularity
D efficacy
E prevalence
F usefulness
选项
答案 D,F
解析 The sentence suggests that vitamin E supplements are ineffective in deterring the disease, and the use of the word "despite" indicates that this ineffectiveness contrasts with how they are widely viewed. The words that fill the blank, then, must mean the opposite of "ineffectiveness." Among the answer choices, the words that do so are "efficacy" and "usefulness." Of the other choices, "potential" is tempting, but it does not contrast as directly with "ineffectiveness," nor does it have a near synonym among the other answers with which it could be paired. "Prevalence" and "popularity" might be initially attractive because the passage suggests that these words might describe the use of vitamin E supplements, but the blank calls for a word that characterizes how they are viewed rather than how they are used.
Thus the correct answer is efficacy(Choice D)and usefulness(Choice F).
