1.         GWD-27-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.

D     为什么答案b不对那

首先first没说错啊 只是说evidence不足

后面那个应该是evidence

明白了，原来作者对是赞同waste这个观点的，我看到however我还以为他反对这个观点呢。
