isuffering

13. 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

I know the answer should be C

But I'm not sure about the meaning and usage of the two phrases "rate of " v.s. "rate for ?

Can any NN help tell the difference?

Thanks in advance.

窃以为，如果放在主语的位置上，是没有区别的。

rate for > rate of

You can consult the explantion of OG.

OG上的解释：when rates means "prices charged," it should be followed by for.

这个题目不知道也可以作对。a/d/e是可以排除的，比较b/c一个用的是动词，一个是名词，你会选什么

isuffering

I see.Thank you, siebel, joywzy, lstzhang.
