OG书上critical reasoning问题。。。

godgod777

20. 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 10 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 sleds can carry more than one rider, an accident involving a wooden sled can result in several children being injured.

我没看懂标红的问题是什么意思啊？求翻译~谢谢各位！

原文：10年前，塑料的x流行，因为x很快难控制。有个观点关于塑料x更加文献可以消除了，基于事实：去年冬天受伤孩子的数量比十年前多。
问削弱 基于事实的选项。
选择E。原文隐藏了一个中间结论。10年前x有缺点，所以选择木头的了。但是情况就是去年受伤多。

亲！那么题目中论据就是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 10 years ago.这个对吧？削弱对数量这个论据吧？我理解对么？

以下选项，如果属实（in Verland），哪一个最能削弱题目中论据的说服力。
undermine是削弱的意思。
