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?

A.      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.

B.       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.

C.      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.

D.      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.

E.       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.

答案是D。请问E中的position和D中的reasoning’s contention有什么区别？如何区别呢？谢谢了！

E。 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.

选项最后的that position指的就是前面的那个position.

而前面的position是“推理认为证据不足的position”.显然第二句的evidence不是支持这个position的，而是支持推理的。

那D选项怎么理解那两个reasoning contends呢？好糊涂啊感觉。。。。

能看得懂文章说什么，但是这个选项感觉很绕啊。。。

期待NN帮助~
