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 undermine the force of the evidence cited? B. Very few children wear any kind of protecive gear, such as helmets, while sledding. C. Plastic sled can be used in a much wider variety of snow conditions than wooden sleds can. 请问啦一个选项正确呢?因为好像有争议....谢谢!!!

我觉得是E

LOR说因为新鞋发生事故的数量多,所以新鞋危险。问weaken?

B说很少人有保护措施,但这点上,对新鞋和旧鞋的影响不是一样的么

E说旧鞋实际上出事的时候,伤害的人比新鞋多;就是说虽然新鞋事故数量多,但是数量*每次伤害人数,新鞋未必比旧鞋多。
