  GWD-21-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.

 

过去都适用木头雪橇，十年前开始使用塑料雪橇。

 

去年的滑雪受伤人数比十年前的人数多很多               à   塑料雪橇比较危险

(使用塑料雪橇受伤的人比使用木头雪橇受伤的人多)

 

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. 无关本论

B.     Very few children wear any kind of protective gear, such as helmets, while sledding. 不管是使用木头的还是塑料的都没穿护具，并无法使比较基础不同，不会影响结论。

C.    Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.  使比较基础不同（使用塑料的基数比使用木头的基数大）不能用绝对数字来看，要看受伤的人占使用该类型雪橇的总人数的百分比。

D.    Most sledding injuries occur when a sled collides with a tree, a rock, or another sled. 支持结论（因为塑料雪橇不易煞车所以容易发生冲撞，所以受伤人数较多且多为冲撞受伤、所以较危险）

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.

支持结论（因为单一木头雪橇出事会有好几个人受伤，但是其整体受伤的人数依旧比塑料雪橇的受伤人数来得低，可见得雪橇出事故的件数更少了，所以塑料雪橇比较危险。
