6. 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.
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.

翻译第一题的a
受了SYSTEM这个杂志广告刺激却从来没有购买商品的杂志订户中,三十或三十以上年纪的人比三十以下的人多的多.

Marrow的解释是正确的.

补充:
5题,我觉得关键
1.30%
2.MOST
3.under age 35
既然MOST是under age 35,而30%是由Subscriber发出,那么剩下的70%或少一些,必然由非subscriber发出.也就是答案E中的又一个"MOST".关键词!
