GWD 21-30

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 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?

A.    A few children still use traditional wooden sleds.

B.      Very few children wear any kind of protective gear, such as helmets, while sledding.

C.    Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.

D.    Most sledding injuries occur when a sled collides with a tree, a rock, or another sled. (B)

E.      Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured.

why not C?

应该选C；B各打一拳，等于没打，C是他因削弱，虽然拳头软，但还是打了，而且是针对plastic sleds,也只能选它了；好像是新东方给过的题我做过。

答案应为C.

本文结论涉及到两个对象进行比较,而ABDE全不存在两个对象的比较,因此全部为无关选项,排除.

C should be the right answer

我也觉得是C，以前做过，记得答案是C

注意LOR是：因为穿塑料鞋时发生的事故数量比穿木鞋多，所以塑料鞋比木鞋危险。

不同意C

塑料鞋比木鞋使用范围更广，所以出事机会更多；哪里weaken了？

我觉得E

木鞋出事总是多人事故，虽然塑料鞋出事数量多，但出事数量*出事人数后，塑料鞋未必比木鞋多，所以塑料鞋未必比木鞋危险

正确答案C。

推出more dangerous的应该是事故发生率高。C说的是，塑料sled事故总数多，是因为它使用范围广，使用量大，整个基数提高，而未必是它安全性能低。就好象，交大男生比财大男生优秀的多，并不能说明交大男生优秀率>财大男生优秀率，而只是交大男生基数大而已。

mm是什么学校的？ 呵呵 偶们学校被你夸了
