. GWD21-Q30:C / B
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.
Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured
削弱的话，B选项不就正好说明不是plastic sleds危险，而是小孩们没有装备防护道具~~~
C选项说plastics sleds课使用的范围广乐，不是就间接说明plastic sleds危险吗？ 那么C选项不是就是支持选项了~~怎么会是削弱呢？？？
做这个题一看C我就说是支持肯定不选 pass掉了~~~ 请教 谢谢~~
