Q30:

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?

1. A few children still use traditional wooden sleds.
2. Very few children wear any kind of protective gear, such as helmets, while sledding.
3. Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
4. Most sledding injuries occur when a sled collides with a tree, a rock, or, another sled.
5. Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured.

参考答案为C。谁能解释一下原因，我觉得B更合适

同意选C.

B没有说"Very few children wear any kind of protective gear"是以前还是现再.要是现再的话,有可能是不带helmets引起的.

这道题目一直有争议

似乎没有一个是对的,但是官方答案貌似是c, c的描述写的不好, 没有表达出应该表达的意思
