1.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.



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.
KEY:C
我选的是B，但题目说的是undermines force of evidence,不知道我哪里错了～
请求赐教啊，各位～

B既不能增强也不能削弱，是个无关选项

伤追人

这题我之前也做错了，貌似论坛上有人是这么解释的

c 中，因为plastic sleds比 wood sleds 可以在更多的场合用，所以用的人多了，自然受伤的人也多了，所以削弱了结论plastic sleds比wood 危险。

这题非常毁我三观！！！！

推论：plastic sleds are more dangerous （than wooden sleds ）

事实：the number of children injured while sledding was much higher last winter than it was ten years ago

如果B成立，那么10年前的孩子和现在的孩子都没护具，无法解释plastic sleds更危险。况且原文根本没提到护具，所以B选项为无关选项。

接着用POE可以得出正确答案C。

这个题我想破脑袋都没想明白。。既然原题已经说了“the fact that the number of children injured while sledding was much higher”，那plastic sleds能用在其他一万个地方又有什么关系？受伤还是while sledding啊。。。

c是正确选项，因为c产生了比较，直接解释了the number of children injured while sledding was much higher last winter than it was ten years ago.算是给出了他因。b选项都没有讲是针对最近，还是针对过去，不能削弱。To: kwok1123,原题是说plastic sleds能用在更多的地方，这样就会产生更多的the number of children injured。打个具体的比方，比如以前我们只在游泳池玩，受伤害的可能性很小，现在我们去大海玩，受伤害的可能性就大很多了。文章中说的就是在sledding的时候受伤。
