一道逻辑 不明白

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.






答案选C?
塑料的可以在更多condition下 使用 怎么就weaken 它引起的事故少了呢？

更多的环境下能够使用  所以增加了受伤和事故的可能性

唉 感觉gmat逻辑很不靠谱啊。。。谁说增加用的多一定事故多。。。

言外之意就是告诉你，不是材料本身造成，而是因为plastic 用处多，所以出问题几率自然就大。
