※ 引述《kenting15 (我不像我)》之銘言：
: 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?
: C. Plastic sleds can be used in a much wider variety of snow conditions than
: wooden sleds can.
: 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.
: 我選E 答案是C
: 但我想了很久還是不知道位何C可以weaken
這題用的是複因反駁
要注意的是題目第五行提到 "the number of children injured"比起十年前要多
答案給的是
因為塑膠雪橇比起木製雪橇可以在更多情況下使用
也因此使用的機會跟使用人數都會比較多
所以受傷的人數比較多也是合理的
並不表示是因為塑膠的比木製的危險
所以反駁了結論
