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?
  • AA few children still use traditional wooden sleds. 分析该选项
  • BVery few children wear any kind of protective gear, such as helmets, while sledding. 分析该选项
  • CPlastic sleds can be used in a much wider variety of snow conditions than wooden sleds can. 分析该选项
  • DMost sledding injuries occur when a sled collides with a tree, a rock, or, another sled. 分析该选项
  • EBecause the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured. 分析该选项
