ＧＷＤ21－30 紧急！

C is correct, and B is not even related

C is correct b/c it is possible that many people got injuried when they were using the sleds to do special sleding that people couldn't do ten years ago.  That is, the increase of injuries is due to the fact that people use sleds to do more dangerous moves, rather than due to the plastic materiral itself.

C,要削弱的是塑料的危险,比较危险实在其他情况相同的情况下,所以C说明有其他情况存在,所以是削弱!!!

B根本就没有比较,哪来的削弱呢?

30. GWD21-Q30:

Fact 1:
                In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. 

Fact 2:Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. 

Premise :
                The concern that plastic sleds are more dangerous is clearly borne out
                

Fact 3:
                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?

 

1. A few children still use traditional wooden sleds.

2. Very few children wear any kind of protective gear, such as helmets, while sledding.

3. Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.

4. Most sledding injuries occur when a sled collides with a tree, a rock, or, another sled.

5. Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured.

 

I’ll go for C.
                    

 

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

题目要weaken 的部分应该是针对the concern that plastic sleds are more dangerous.

C: 因为他因, 造成去年用plastic 比用10 年前用wood 受伤的人口多.
                    

其它选项看似无关

同意此说法。。

Please pay attention to the question: "Which of the following, if true in Verland, most seriously undermines
                    the force of the evidence cited?" NOT THE CONCLUSION!

C provides another evidence to support the conclusion. Because plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can, they are more dangous than wooden sleds.  This reason or evidence is much more relevant and forceful than the fact that the number of children injured while sledding was much higher last winter than it was ten years ago to support the conclusion.  Thus, C undermines the force of the evidence.

题目要的是undermine evidence

,这个论据是说P比W are harder to steer and slow. 

为了削弱它,就说Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.[C],

是别的原因导致了结论,意思是这个EVIDENCE不适用于这里,不知明白否?
