一道prep求助

69.  Editor:  Articles in GardeningMagazine often spur sales of the plants they describe, particularly amongpeople new to gardening.  Accordingly, wewill no longer publish articles or accept advertisements praising the beauty ofrare wildflowers.  Most such plants soldto gardeners have been difficult to propagate under cultivation, so plantsellers often collect them in the wild. Our new policy is part of our efforts to halt this yearly plundering ofour native plant populations.

Which of the following,if true, casts the most doubt on the wisdom of the magazine's new policy as away of pursuing the intended effect?

(A)  When people new to gardening buy plants, they often fail to takeadequate care of the plants that they buy and become discouraged from buyingthose varieties again.

(B)  Plant sellers who sell rare wildflowers have no reasonablyinexpensive alternative way to offer their wares directly to new gardeners.

(C)  The demand for rare wildflowers rarely exceeds the number of suchplants 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 thatcreate suitable soil conditions or insects and birds that disperse seeds.

(E)  Revenues from sales of plants collected in the wild are supportingthe discovery of new low-cost techniques enabling rare wildflowers to bereadily propagated in nurseries.

我选了A。是这么想的：如果新政策不实行，杂志继续宣传野花花是多么漂亮，人们根据杂志宣传继续去买野花花，他们买回家以后，就会发现这些花花其实不好养，以后就不会再买了。所以最好的方案应该是杂志继续宣传这些野花花很漂亮，放任人们去买，人们就会自动发现他们的决定是多么愚蠢错误，实现intended effect。

      而如果实行新政策，这么好的结果就实现不了，所以对于新政策我们应该抵制，它是存在doubt的。

这个嘛。。。也不是说不可以，but，每个人都来买个野花，野花死光光了就不用保护了呀

A选项和政策没什么关系，并且楼主人为假设了不实施政策（人们被吸引买花后被discourage）比实施政策（人们不被吸引去买花）要好，万一人们压根不被吸引去买花比先买有不买更有利于保护野生花呢？做CR不能带入自己的假设。
