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. (E)

不太明白蓝色那句话，谁可以帮我解释一下因果关系~

同意！

-Most such plants sold to gardeners have been difficult to propagate under cultivation, so plant sellers often collect them in the wild。
这些wildflowers因为很难在人工培育下授粉（所以人工培育的数量不多），所以卖家要经常在野外收集这些植物。
这本杂志今年的理念是保护大自然植物，所以要遏制这些卖家的行为，所以决定减少在杂志上宣传wildflowers。

问weaken，看一下答案：
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. 新手买植物，总是照顾不周从而打消继续买的积极性。。。原文问要不要少宣传来减少采野花的行为，这个回答没理原文。

B. Plant sellers who sell rare wildflowers have no reasonably inexpensive alternative way to offer their wares directly to new gardeners.
这些卖野花的人没有别的不贵的方法来直接向买家提供花了。。。这个说实话没太看懂，但是感觉跟原文关系不大，原文没说贵不贵。

C. The demand for rare wildflowers rarely exceeds the number of such plants that can be collected in the wild by plant sellers. 对野花的需求远不及花贩子在野外采到的野花。。。无关

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. 谈野花在野外如何授粉。。。无关

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.卖野花所得来的钱用来研究低成本人工授粉的技术。。。所以得继续卖，weaken原文观点。所以选E。

这个理解好像能说得能，如果从削弱的角度来说的话就不合适了，从是否wisdom这个角度正好，看来还是要仔细读题目啊

可是我看了一下正确选项E，好像也不符合这两个。曼哈顿论坛上ron的意思是说E之所以对是因为E找出了人们不会plunder的不同的原因，所以就削弱了。但是方案计划型的削弱不是不能因为还有其它可行方案就削弱目前这个方案吗？

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

我觉得这道题的E可以这样理解：因为问题问的是 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? 也就是下面哪个，在正确的情况下，会使magazine的new policy不wisdom?

(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. 当seller知道怎么培育rare wildflowers而不需要去野外采摘的时候，其实目标自然已经达到，magazine再做任何辅助这个目标达成的事情都是没有必要的，也就是不wisdom

不是很懂为什么选项E是正确选项。看不出和policy有什么关系

猪小王

这题论证过程属于归纳推理。逻辑链：因为articles刺激销售，以及seller采野花补给销售，所以our new policy要停止发文章和广告以便保护野生植物的数量。

Editor根据目前的观察(often spur sales, most such plants have been difficult to propagate under cultivation)来推出一个plan/policy. 题目质疑这个policy是否明智 (wisdom) 不是质疑policy能否达到效果。比如Trump禁止墨西哥人入境美国这个policy is effective but not wise. 归纳推理有先天的缺陷：1. 以偏概全，2. 现在如此推不出未来也如此。答案E说的是目前collect wild flowers这个情况会改变 (new low-cost techniques enabling rare wildflowers to be readily propagated in nurseries). 也就是告诉我们未来和现在不一样，这个policy眼光太狭窄了，不够wise。

A选项一定不对，因为只要new customers因为articles买了wild plants，就已经造成damage，这个答案没有cast doubt on the wisdom of policy，反而是support the policy.

吐槽一句E，卖野花所得收入的所有者是那群辛辛苦苦采集野花的人，然后他们会傻不拉几的把钱捐出去来帮助提 ...

为什么不可能？seller的目的是卖出更多的花，采花还是投资研发培养这些品种只是进货的不同渠道／方法。哪种渠道成本低，供货稳定就用哪种。显然cultivate wild flowers是有价值的，能提供低成本稳定的货源。
