支持C,9楼的说明Perfect。

跑10000公里的车出3次事故，跑10公里的车出2次事故，应该是10000公里的那辆更安全。这题的考点应该是绝对值和相对值概念的比较。

In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number (绝对值大，但并不说明危险)of children injured while sledding was much higher last winter than it was ten years ago.

Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?

B.     Very few children wear any kind of protective gear, such as helmets, while sledding.(相对值小，说明不危险)

对不起，上面贴成B了，重贴一下。

简直晕菜 公说公有理 婆说婆有理...还是选B 他因 ...

恩，觉得应该是C,这样才有比较，如果没有比较，像B和D那样，无论是Plastic sleds 或者是wooden sleds 都能发生，就不能说明问题了。
