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?

Our new policy is part of our efforts to halt this yearly plundering of our native plant populations. Which of the following, if true, support 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 discourged from buying those varieties again. (B) Plant sellers who sell rare wildflowers have no reasonably inexpensive alternate way to offer their wares directly to new gardens. (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 plant's 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 innurseries. 我选C,请n们指正——by jassonw(700,v34)
Articles spur sales of the plants杂志文章能促进所描述的植物的销售particularly among people new to gardening->the rare plants are difficult to propagate under cultivation这些珍稀植物难以人工繁殖->plant sellers often collect them in the wild所以卖植物的经常去野外摘 结论是:no longer publish articles or accept advertisements praising the rare plants不登表扬野生植物的文章->halt plundering of native plant populations就能停止植物的掠夺
(A) When people new to gardening buy plants, they often fail to take adequate care of the plants that they buy and become discourged from buying those varieties again. 无关 (B) Plant sellers who sell rare wildflowers have no reasonably inexpensive alternate way to offer their wares directly to new gardens. sellers没有别的方法提供 野花,只能野外采摘。支持结论。 结论是:停止广告的政策 可以 停止对花的采摘 如果sellers卖的花不少采摘来的,停止广告 和 停止采摘 之间就不存在联系了,这个政策对采摘就没有作用了。。 (C) The demand for rare wildflowers rarely exceeds the number of such plants that can be collected in the wild by plant sellers. 对野花的求很少超过 可采摘到的数量。和结论没有关系,因为花的需求小于供给,所以取消广告对没有作用 (D) The propagation of rare wildflowers often depends on the plant's interaction with other organisms in their environment such as plants that create suitable soil conditions or insects and birds that disperse seeds. 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 innurseries. 卖采摘的野花的收入可以发展养殖野花的技术,所以削弱了结论
