Accordingly, we will nolonger publish articles or accept advertisements praising the beauty of rarewildflowers. Most such plants sold to gardeners have been difficult topropagate under cultivation, so plant sellers often collect them in the wild. Ournew policy is part of our efforts to halt this yearly plundering of our native plantpopulations. [size=12.000000pt]Which of the following, if true, casts the most doubt on the wisdom of themagazine's new policy as a way of pursuing the intended effect?
(A) When people new to gardening buy plants, they often fail to take adequatecare of the plants that they buy and become discouraged from buying thosevarieties again.
(B) Plant sellers who sell rare wildflowers have no reasonably inexpensivealternative way to offer their wares directly to new gardeners.
(C) The demand for rare wildflowers rarely exceeds the number of such plantsthat can be collected in the wild by plant sellers.
(D) The propagation of rare wildflowers often depends on the plants' interactionwith other organisms in their environment, such as plants that create suitablesoil conditions or insects and birds that disperse seeds.
(E) Revenues from sales of plants collected in the wild are supporting thediscovery of new low-cost techniques enabling rare wildflowers to be readilypropagated in nurseries.
先看题目分析，这道题是方案推理模式
方案：no longer publish articles or accept advertisements praising the beauty of rare wildflower（杂志社不再为这些wildflower做宣传）
目标：halt this yearly plundering of our native plant populations.（停止人们对这种植物的掠夺）
题目问的是削弱。在看选项之前通过分析推理模式可以得出答案应该是以下几个方向：1）该方案不能够成功实施 。2）该方案不可以达到相应目标。3）该方案实施后会有一些不好的后果（副作用）（通过以上三个方向可以看出答案应该集中在方案上，也就是说要和方案有关）
另外在做方案推理题时还需特别注意如果给出了实现目标的另一个方案则不能对原方案构成削弱（除非给出的另一个方案和原方案有关系，例如新方案的提出暗含了旧方案不可行，比如说新方案是实现目标的唯一方案等）
