Editor:  Articles in Gardening Magazine often spursales of the plants they describe, particularly among people new togardening.  Accordingly, we will nolonger publish articles or accept advertisements praising the beauty of rare wildflowers.  Most such plants sold to gardeners have beendifficult to propagate under cultivation, so plant sellers often collect themin the wild.  Our new policy is part ofour efforts to halt this yearly plundering of our native plant populations.

Whichof the following, if true, casts the most doubt on the wisdom of the magazine'snew policy as a way of pursuing the intended effect?

A.When people new to gardening buy plants, they often fail to take adequate careof the plants that they buy and become discouraged from buying those varietiesagain.

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 plants thatcan 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.

helr说该种推理为方案模式推理。因为题干中没有论证方案可行性的句子。

疑问： 文中的第一句话：Articles in Gardening Magazine often spur sales of the plants they describe, particularly among people new to gardening.不是论证了该杂志会影响到刊登的植物的销量吗？我是否可以这样理解，既然该杂志会影响到刊登的植物的销量，所以如果不刊登rare wildflowers，就算保护了rare wildflowers，也就是达到目的了。所以该题我理解的分类应该是因果推理模式。
结论：Our new policy is part of our efforts to halt this yearly plundering of our native plant populations.
因：因为杂志会影响到刊登植物的销量
果：不刊登rare wildflowers，就算保护了rare wildflowers
