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?
前面老师讲的没有听懂：第一句都说了"have claimed that"，它不就是个claim吗？为什么不能在ab里面选？

In 1983 Argonia's currency, the argon, underwent a reduction in value relative to the world's strongest currencies. This reduction resulted in a significant increase in Argonia's exports over 1982 levels. In 1987 a similar reduction in the value of the argon led to another increase in Argonia's exports. Faced with the need to increase exports yet again, Argonia's finance minister has proposed another reduction in the value of the argon.
 
Which of the following, if true, most strongly supports the prediction that the finance minister's plan will not result in a significant increase in Argonia's exports next year?
