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?

AA few children still use traditional wooden sleds.
BVery few children wear any kind of protective gear, such as helmets, while sledding.
CPlastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
DMost sledding injuries occur when a sled collides with a tree, a rock, or, another sled.
EBecause the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured.

正确答案: C

嗯，我区别不出来是哪种类型，就直接说选项把。。
逻辑链是plastic sleds更harder to steer，所以更容易造成孩子受伤，所以更危险。
你先想想为什么排除B，是因为B这种情况在过去和现在都会发生，所以不能成为现在孩子受伤更多的原因；那同理，D选项也是过去和现在都会发生的情况，也不能成为原因。
而C选项说plastic sledding比wooden sled能用到的地方多，所以造成孩子受伤更多，而不是因为harder to steer，所以造成孩子受伤更多。

ps：我今天刚看helr大神的笔记，感觉神一般的存在啊。。不过该方法最大的难点我觉得是不好判断类型。
