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.
