请问JJ88题GWD变体是不是选B呢?谢谢。。。 88. 碰到另一道GWD的CR变体,就是塑料滑雪板比木头滑雪板事故高那个,答案被改了,但意思还是说因为塑料滑雪板比木头的便宜,所以用的人多。 GWD21-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? 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.
