把D带入答案:
A new hair-growing drug is being sold for three times the price, per milligram, of what (of the price that) the drug’s maker charges for another product with the same active ingredient.
就是:drug is sold for (3 times) the price of the price that the maker charges for the product. 这是很标准的表达。
...for three times the price, per milligram, of what the drug’s maker charges for another product with the same active ingredient. 我的理解是这样的:three times the price of the price which the drug's maker charges for another prodcut...第一个price指现在三倍的价钱,第二个price指drug's maker正常charge的价钱。用price which来带入what可能会好理解一些。
ANSWER: C I have researched this question, both here on ST and in the grammar/style texts, and I cannot find any support for D in this case (or, generally, as "of what" is simply poor style, even when it is not grammatically incorrect). This is a question that deals with correct usage of a relative pronoun (that, which, who, whom, what, and whose). The function of a relative pronoun is to introduce a subordinate clause and relate it to another antecedent word or idea. In this sentence, that idea is "...three times the price..." The relative pronouns which would work here are: that and which (not "what," not "of what, not "at which"). So, A, B, D, and E do not work with this construction. And, by the way, "of what" can nearly always be said in a better, more stylistically acceptable fashion. This sentence should read, "A new hair-growing drug is being sold for three times the price, per milligram, that the drug's maker charges for another product with the same active ingredient." The first part of the sentence is the main (or independent) clause. The last part of the sentence is the subordinate (or dependent) clause. "That" refers to "three times the price" clearly and it introduces the subordinate clause correctly. C is the best answer, FOR THIS CONSTRUCTION. If "the price" were omitted from the sentence, then this would be correct, "A new hair-growing drug is being sold for three times, per milligram, what the drug's maker charges for another product with the same active ingredient." But, even with this construction, "of what" does not work.
A recent review of pay scales indicates that CEO’s now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times in 1980.
that CEO’s now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times
that, on average, CEO’s now earn 419 times the pay of blue-collar workers, a ratio that compares to 42 times
