请教一道OG紫皮上的题

76．  State officials report that soaring rates of liability insurance have risen to force cutbacks in the operations of everything from local governments and school districts to day-care centers and recreational facilities．

(A)  rates of liability insurance have risen to force

(B)  rates of liability insurance are a force for

(C)  rates for liability insurance are forcing

(D)  rises in liability insurance rates are forcing

(E)liability insurance rates have risen to force

Rhetorical construction + Verb form + Idiom

This sentence does not clearly present its main point．It should be revised to eliminate redundancy, clarify cause and effect relationships，and use the word rates correctly．The adjective soaring and the verb form have risen express the same idea，so the verb should be omitted and replaced with are forcing，which shows clearly what the soaring rates are doing．Moreover, the present progressive verb tense(are forcing) indicates this is an ongoing problem．when rate means a price charged, it is followed by the preposition for．

A  For should be used following rates, not of, redundant verb form have risen．

B  For should be used following rates，not of, the wordy construction are a force is not as clear as the more concise are forcing．

C  Correct．The sentence is concise and uses the correct preposition following rates，and the present progressive verb tense properly reveals an ongoing situation.

D  Rises repeats the idea already expressed in the adjective soaring．

E  Have risen repeats the idea expressed in the adjective soaring．

The correct answer is C．
