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.

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.

为什么答案是C啊？怎么想都不明白，我做的时候选E的~

Plastic sled用的范围广，因此小孩受伤的概率也大；如果和木头的板在同等条件下使用，受伤的概率就可能不会比木头的大，削弱。

哦~~~~~~~~~那E错在哪儿咧？

这道题的矛盾主体是Plastic sleds ，所以，答案中应包含对Plastic sleds 的解释，因此只能选C，E选项说的是wooden sled ，与题中问你的为什么plastic sleds 为什么增多无关，而且，E选项本来就是错的，E 的意思是wooden sled 的缺点，说明wooden sled 产生了更多的injuries，与题目矛盾
