来自800score
The new sports car is heavier than for a performance automobile, but it is exceptional because of its high-powered engine.
A) usual
B) it is usual
C) one usually is
D) is usual
E) has been usual
It's from 800 score. Here is its explainD) is the correct answer. It employs the parallel construction, 'the sports car is.... than (is) usual for a ...'. (A) is ruled out because it does not create a parallel comparison. In (B), the 'it' is redundant; so is the 'one' in (C). (E) is incorrect because of the verb tense, which should stay in the present. (D) is the best answer because it uses parallel construction.
