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.

我又想了一遍。。看看是不是这个意思。。
杂志原来宣传什么什么就畅销。。但是那个wild的繁衍能力不好。。所以杂志不宣传它了。。就为了保护population数量。。
也就是 其实繁衍能力可以得到改善的话。。杂志这个明智的举动就没有意义了。。
是吗？

我也是，不知道你看了多长时间，我断断续续看了将近一个礼拜的狗，晚上本来打算再看看的，现在反而轻松了，无事可干了。无所谓了都，就当看看自己真正的实力有多少吧。

削弱题嘛，AB型的，主要思路就是有另外一个原因让B不成立，用这个思路就选出E了，因为稀有的植物在室内也可以很好繁殖了，所以就推不出结论了
