第十一题（gardenmagazine，削弱）
Editor: Articles in Gardening Magazine often spur sales of the plants
they describe, particularly among people new to gardening. Accordingly,
we will no longer publish articles or accept advertisements praising the
beauty of rare wild flowers. (plan) Most such plants sold to gardeners
have been difficult to propagate under cultivation, so plant sellers
often collect them in the wild.(reason,根据) Our new policy is part of
our efforts to halt this yearly plundering of our native plant
populations.
Which of the following, if true, casts the most doubt on the wisdom of
the magazine's new policy as a way of pursuing the intended effect?
A.When people new to gardening buy plants, they often fail to take
adequate care of the plants that they buy and become discouraged from
buying those varieties again.
B.Plant sellers who sell rare wildflowers have no reasonably in
expensive alter native way to offer their wares directly to new
gardeners.
C.The demand for rare wildflowers rarely exceeds the number of such
plants that can be collected in the wild by plant sellers.
D.The propagation of rare wildflowers often depends on the plants'
interaction with other organisms in their environment, such as plants
that create suitable soil conditions or insects and birds that disperse
seeds.
E.Revenues from sales of plants collected in the wild are supporting the
discovery of new low-cost techniques enabling rare wildflowers to be
readily propagated in nurseries.
狗主的答案是E，可是我完全不明白这在削弱什么？

原文的意思是这个杂志因为说通过不推出‘野花好看’的文章而达到一个大家不去伤害野花的结果。 而选项削弱的是正是因为那些在杂志上出文章做广告的商家通过这种在野花上的收入使得野花能够在温室里生存，得意保护。所以削弱了argument d 前提。
