 GWD21-Q30:

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.

答案是C. 可是我决的是E呀... 有人说E加强了.但是我觉的是WEAKEN呀..

E就是说WOODEN的其实更加DANGEROUS. 因为一个ACCIDENT可以导致多人伤亡呀.......

Yeah... the answer must be C, because (let's ignore A,B,D)

The evidence :  by the fact that the number of children injured while sledding was much higher last winter than it was ten years ago.

E shows that in merely one accident, the injury which brought by wooden sled is more than by plastic one. However, according to the evidence, the total number of accidents by P is more than by W. ==> Strengthen the aregument that using plastic one is more dangerous.

C shows the opposite.

Correct me if i'm wrong.
