In 1960, 10 percent of every dollar paid in automobile insurance premiums went to pay costs arising from injuries incurred in car accidents. In 1990, 50 percent of every dollar paid in automobile insurance premiums went toward such costs, despite the fact that cars were much safer in 1990 than in 1960.
Which of the following, if true, best explains the discrepancy outlined above?
(A) There were fewer accidents in 1990 than in 1960.
(B) On average, people drove more slowly in 1990 than in 1960.
(C) Cars grew increasingly more expensive to repair over the period in question.
(D) The price of insurance increased more rapidly than the rate of inflation between 1960 and 1990.
(E) Health-care costs rose sharply between 1960 and 1990.
这道题的答案是E。我想请问大家，这个E怎么得出来的？
另外C为什么不对？
谢谢！
谢谢楼上。不过我还有一个问题：
原文中的 insurance premiums went to pay costs arising from injuries incurred in car accidents
具体是什么意思？ 是说保险费来自于车事故中的injuries??
所以是说这个insurance premium不包含车本身的修理费（repair premium)所以C才错误吗？
