紧急求助GWD21-30是OG里面的哪道逻辑题啊?

我记得这道是OG里的,而且答案是D,但是现在看到讨论说是C.我翻了两个小时的OG死活就是找不到!我要疯了! 这题到底在那里啊? 哭死了!!哪个好人救救我吧...精神严重崩溃中...

30. GWD21-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?

1. A few children still use traditional wooden sleds.
2. Very few children wear any kind of protective gear, such as helmets, while sledding.
3. Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
4. Most sledding injuries occur when a sled collides with a tree, a rock, or, another sled.
5. Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured

你好。10版OG肯定是没有了。如果有应该是11版的OG但是我没做完。

D确实是错误。削弱的是最后一句话，而D只不过是解释了受伤的原因。和是否是由塑料引起的无关。

谢谢ls! 我做的11og,非常奇怪今天死活都找不到

我也没做其他的什么资料啊,除了GWD.我记得当时我选了C,然后看后面解释是D.难道我记反了

明天接着找!

呃，那答案是C还是D呢？

我看GWD里的答案是C的？

i think the answer is D
