24. The problem that environmental economics aims
to remedy is the following: people making
economic decisions cannot readily compare
environmental factors, such as clean air and the
survival of endangered species, with other costs
and benefits. 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 ecisionmaking
(E) not at all, since the argument is circular,
taking that conclusion as one of its premises

答案A。 没看懂。

Thus, environmental economics is stymied by what motivates it. 是怎么推出来的？

番茄炒蛋

原文说的是人们作出决定需要知道环境值多少钱
而a中说了，只有当人们作出了决定之后才能确定环境值多少钱
所以a就很好的指出了原文的矛盾之所在咯
