一道BLODFACE的题！大全没有，困惑中！

blink184

是XDF蓝皮里面的第88题，我实在搞不懂啊！请各位大牛帮忙！
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 spend, annual emissions of those 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?
D. The first is a position that the reasoning contends is inadequately supported by 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.

我选择的是E，可是答案是D。不知道为啥D说第二个是用来支持推论的证据，分明说了第一段boldface表达了一个认为推论很拙劣的态度啊！我觉得第二个是用来支持作者态度（即position）的证据！

另外，contend不是动词吗，后面怎么还有个is 呢？The first is a position that the reasoning contends is inadequately supported by evidence这句话怎么翻译啊？真的想不通为什么选择E。

这个题黑体字，一个再however之前，一个再后，说明，在前的一句话，position与作者的态度相反，而后一句，与作者的态度相同，E的后半句错了，作者是反对前一句的position的，D，是说evidence support reasoning，是作者的观点，当然对了
