As environmental economists recognize, solving this problem requires assigning monetary values result from people comparing costs and benefits in order to arrive at economic decisions. Thus, environmental economics is stymied by what motivates it. If the considerations advanced in its support are true, the passage’s conclusion is supported (A) strongly, on the assumption that monetary values for environment factors cannot be assigned unless people make economic decisions about these factors (B) strongly, unless economic decision-making has not yet had any effect on the things categorized as environmental factors (C) at best weakly, because the passage fails to establish that economic decision-makers do not by and large take adequate account of environmental factors (D) at best weakly, because the argument assumes that pollution and other effects on environmental factors rarely result from economic decision-making (E) not at all, since the argument is circular, taking that conclusion as one of its premises 看不懂什么意思，理不清。。。。。。== KEY A作者: s_dUSA 时间: 2012-9-13 06:04
tough one
"motivate": solving the prblem by assigning monetary value.
the conclusion, this motivation actually prevent the environmental economic from achieving its aim (aim: make people readily compare environmental factors, such as clean air and the survival of endangered species, with other costs and be )
But if we only look at the stimulus, it is pretty much nonsence, but if you add the assumption in A, it works very well.
Because, according to this assumption, the solution of this problem, which is assigning monetary value, will auutomatically leads to the problem, whcih is that people make economic deicison.
then we turn back and loook at the first sentence of this stimulus, "people making economic decisions cannot readily compare environmental factors, such as clean air and the survival of endangered species"
we will find out that because of this assumption, the solution weill leads to the exact problem this solution going to solve!
