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 wildflowers.  Most such plants sold to gardeners have been difficult to propagate under cultivation, so plant sellers often collect them in the wild.  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 inexpensive alternative 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

答案是E。我也同意。但是不明白为什么A不对。

我是这样理解的：由于那些新人他们买花后来都种不好都种死了，所以他们就不会再去买那些稀有的野花，那么没有这个需求了，卖花的人就不会去采花，也能得到E的结果：稀有的花不会减少

请NN解答

A选项说的是不会again买，说明还是有人买。而且如果这些种花的人不是new to gardening, 懂得护花，他们就会重复购买。所以A不削弱。

Rainbeauty

额。。。。。。。。。好吧 可是A和E项比起来的话还是觉得A更合理一点丫

此题是计划目的型削弱题。
计划：we will no longer publish articles or accept advertisements praising the beauty of rare wildflowers.
目的： to halt this yearly plundering of our native plant populations.
此类题目的做法是1.否定计划自身的可能性。
or    2.削弱计划实施后能够达成目标。要求选项和plan要高度相关。
A选项显然不符合上述任意一个，所以无关。
