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?
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.
Plant sellers who sell rare wildflowers have no reasonably inexpensive alternative way to offer their wares directly to new gardeners.
The demand for rare wildflowers rarely exceeds the number of such plants that can be collected in the wild by plant sellers.
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.
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.
情景：我们不能再夸赞野生花漂亮了。由于野生的花很难被养殖，所以卖植物的人会直接去野外摘这些花。如果我们不再赞扬野生的花漂亮，那么应该可以阻止野生的花被掠夺。
推理：推理文段给出了一个方案，即，we will no longer publish articles or accept advertisements praising the beauty of rare wildflowers，并且结论句是这个方案的目标。问题让我们削弱方案是否能达到预期的效果，因此文段的推理方式为：方案推理。
本题的推理结构为：
目标：To halt this yearly plundering of our native plant populations
方案：We will no longer publish articles or accept advertisements praising the beauty of rare wildflowers
选题方式：方案推理有三个评估方向，简而言之，即，答案选项一定和方案的内容相关。其实本题最重要的就是要说明就算没有杂志的引导，顾客们依然对野生花有兴趣。（方案无法达成目的）
选项分析：
A选项：当新的花匠购买植物的时候，他们经常不能很好的照顾这个植物并且不会再次购买这个植物。本选项和方案没有关系，花匠已经购买的植物应该是杂志已经展示过的，可以排除。
B选项：那些卖野生植物的人没有便宜的方法直接将他们售卖的植物展示给花匠。若卖花的人可以不用杂志也能把美丽的花让花匠们看到的话，那么就算杂志不展示野生的花了，花匠们对于野生花的需求可能依然不会改变，从而使得杂志的方案无法达成目的，属于CQ1：方案的可行性问题。因此本选项可以加强推理文段。
C选项：对于稀有野生花的需求很少能超过它们实际的供给量。本选项讨论是稀有野生花的产量问题，没有提及方案，可以排除。
D选项：稀有野生花的繁衍经常是依靠它们和别的生物的配合来完成的，比如那些能创造合适生存土壤的植物和能传播花粉的鸟。本选项谈论的是稀有植物的繁衍方式，和推理文段中的方案无关，可以排除。
E选项：Correct. 售卖稀有野生植物得来的收入可以支持卖花的人研发低成本的技术来人工养殖这些花。若有技术可以人工养这些稀有的花，那么这些卖花的人也就不用去野外采摘这些花了，这甚至可以减少稀有野生花的消耗，因此可以使得方案无法达成目的。
逻辑链：不刊登稀有野花的文章（措施）→阻止野花的数量的减少（目的）
答案：卖植物的钱用来研究廉价的给野花授粉技术
削弱：其他因素阻碍目的达成。即：不刊登这类文章就没有卖植物的钱，也就失去授粉技术的资金，野花的数量还是会减少。
