A year ago the government reduced the highway speed limit, and in the year since, there have been significantly fewer fatalities than were there in the previous year. Therefore, speed limit reduction can reduce traffic fatalities.

The argument is most vulnerable to the criticism that it takes for granted that（注意：这个题问削弱）
A. highway traffic has not increased over the past year
B. the majority of drivers obeyed the new speed limit
C. there is a relation between driving speed and the number of automobile accidents
D. the new speed limit was more strictly enforced than old one
E. the number of traffic fatalities the year before the new speed limit was introduced was not abnormally high

选E把我觉得
E是为了说死亡率跟限速其实是没有什么关系的

不知道对不对

把问的搞明白，问的是：这个argument最站不住脚，是因为它理所当然地认为（it takes for granted that），也就是argument自己假设：

C正解，“前后桥梁型”，理所当然地认为车速和交通事故有联系。

E怎么不对了啊。。。

3楼已经解释咯,
E 选项:因为想当然的认为前一年事故超多, 所以限速导致事故变少
我不懂B 为什么不对, 可有人解释一下?
