250. Domestic automobile manufacturers have invested millions of dollars into research to develop cars more gasoline-efficient even than presently on the road.
(A) into research to develop cars more gasoline-efficient even than presently on the road
(B) into research for developing even more gasoline-efficient cars on the road than at present
(C) for research for cars to be developed that are more gasoline-efficient even than presently on the road
(D) in research to develop cars even more gasoline-efficient than those at present on the road
(E) in research for developing cars that are even more gasoline-efficient than presently on the road
Solution:
Comparison + Idiom
OG Solution
Choice D, the best answer, uses the preposition than to compare two clearly specified and grammatically parallel terms, the cars the manufacturers hope to develop and those at present on the road. In A, the phrase more gasoline-efficient ... than presently on the road does not identify the second term of the comparison. In B, the misuse of modifying phrases produces an ambiguous and awkward statement: even more gasoline-efficient cars could refer either to more cars that are efficient or to cars that are more efficient. Choices B, C, and E all use research for [verb] where the idiom requires research to [verb]. In addition, C awkwardly separates even from more, and C and E again fail to indicate the second term of the comparison.
