以下是引用boborich在2005-11-1 3:48:00的发言：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.  lastic 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. 我选E，对不对？
逻辑是这样的，木头的容易操作，塑料的跑的快但不易操作。人们得出结论：塑料的危险，因为上个冬天的孩子跌伤的多于十年前。要求是找出个消弱的说法。
快--跌伤的大孩子多了----危险。
a，一些孩子还在用老式的木头东西。这个跟危险与否没有关系。
b，滑雪时候，没有孩子用防护装置。大家都没有用,对说明没有影响.
c，塑料的比木头的要用的广泛。
d，大多数滑雪事故是孩子跟其他物品碰撞时发生的。事故原因，跟危险无关。
e，因为木头的能载多人，所以木头的发生事故能造成多人受伤。说的是木头的，没有提到塑料的。
这样看来的话，c要正确，数学问题了，同比，基数大了，数字就多了,所以造成孩子受伤的不是塑料的更危险.
请指教,谢谢.
