Q20:Critics of certain pollution-control regulations have claimed that the money spent over the last decade in order to reduce emissions of carbon monoxide and of volatile organic compounds has been wasted. The evidence they offer in support of this claim might appear compelling: despite the money spent, annual emissions of these pollutants have been increasing steadily. This evidence is far from adequate, however, since over the last decade a substantial number of new industrial facilities that emit these pollutants have been built.

In the reasoning given, the two portions in boldface play which of the following roles?

1. The first identifies a claim that the reasoning seeks to show is false; the second is evidence that has been cited by others in support of that claim.
   
2. The first identifies a claim that the reasoning seeks to show is false; the second is a position for which the reasoning seeks to provide support.
3. The first is a position that the reasoning contends is inadequately supported by the evidence; the second is a position for which the reasoning seeks to provide support.
4. The first is a position that the reasoning contends is inadequately supported by the evidence; the second is evidence used to support the reasoning’s contention.

5. The first is a position that the reasoning contends is inadequately supported by the evidence; the second is evidence that has been used to support that position.

答案D,我觉得A更有道理,因为the second是对 the first的反驳，而不是support 。

A: the second is evidence that has been cited by others in support of that claim. 说的不正是support吗?

D: the second is evidence used to support the reasoning’s contention. second是对reasoning的support. reasoning是对 the first的反驳. 不正是the second是对 the first的反驳吗?

谢谢啦!!!
