To figure out what the missing words are, try to predict their definitions by using keywords from the prompt. Here, there are
three keywords: “answer,” “rarely,” and “address.” “Answer” and “address” are both modified by missing words that must refer

opposites: Nixon was able to answer questions one way and rarely answered questions the other way. Thus, the missing
words’ meanings cannot be predicted, but the correct choice must provide a pair of antonyms. Of the choices, only choice (D)
provides a pair of antonyms, as obliquely means not in a straightforward manner, while directly means in a straightforward
