GWD-21-Q30 children sledding

Sonehri

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证实, 支持 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.    lastic 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.

答案是C我也想通了，可是D为什么错？
他因说明受伤的人数不和雪橇是木头的还是塑料的有关啊

D既然跟sled是木头还是塑料没有关系，那么这个选项就是无关选项了，因为他的存在与否不能支持或者反驳作者的观点呀。所以是没有意义的存在。
