快考了，请教一道逻辑jj，谢谢了

Environmental organizations want to preserve the land surrounding the Wilgrinn Wilderness Area from residential development.  They plan to do this by purchasing that land from the farmers who own it.  That plan is ill-conceived:  if the farmers did sell their land, they would sell it to the highest bidder, and developers would outbid any other bidders.  On the other hand, these farmers will never actually sell any of the land, provided that farming it remains viable.  But farming will not remain viable if the farms are left unmodernized, and most of the farmers lack the financial resources modernization requires.  And that is exactly why a more sensible preservation strategy would be to assist the farmers to modernize their farms to the extent needed to maintain viability.

In the argument as a whole, the two boldface proportions play which of the following roles?

A.    The first presents a goal that the argument rejects as ill-conceived; the second is evidence that is presented as grounds for that rejection.

B.    The first presents a goal that the argument concludes cannot be attained; the second is a reason offered in support of that conclusion.

C.    The first presents a goal that the argument concludes can be attained; the second is a judgment disputing that conclusion.

D.    The first presents a goal, strategies for achieving which are being evaluated in the argument; the second is a judgment providing a basis for the argument’s advocacy of a particular strategy.

E.     The first presents a goal that the argument endorses; the second       presents a situation that the argument contends must be changed if that goal is to be met in the foreseeable future.

答案选D，为什么不选A呢？请教大家了！

是GWD的题，在逻辑区里有讨论过的，可以按题号来搜索。

值得注意原文态度的是，作者对第一句话提出的goal “preserve the land” 不反对而是支持的，

作者反对的是用"plan to do this by purchasing that land"的想法

结论是"a more sensible preservation strategy would be to assist the..."

环保组织倡议去保护耕地是，不能通过买入耕地实现的，而，帮助农民自力更生是合理的策略。
