提供下楼主说的那个GWD考古逻辑

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. Then concern that plastic sleds are more dangerous is clearly borne by the fact that the number of children injured while sledding was much hifher last winter than it was ten years ago.

Which of the following, if truein Verland, most seriously undermines the force of the evidence cited?

A. A few children still use traditional wooden sleds.
B. Very few children wear and 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.


Answer:  C
