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 half 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 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 in nurseries.

想請問大家對這題的看法，這邊題目上問削弱，我選E，因為可以藉由收入促進人工繁殖的產能

若改問加強，我對B跟D很猶豫，B雖說花商沒有像雜誌一樣便宜的管道，但他也可以用貴的管道做廣告

D說這植物繁殖要看外在環境因素，但似乎也不表是人工無法培育

請問大家，削弱跟大家的看法各是如何呢？謝謝！

拜託大家幫幫忙了><謝謝!!

编者：刊载在杂志上的文章能刺激那些园艺初学者去买花。杂志不会再刊载宣传稀有野花的文章了，因为大多数的稀有野花是很难人工培育的，所以卖花人要去野外采花。这个不再宣传的目的是为了让我们本土的植物数量不再削减。
削弱。也就是不能让本土植物数量不削减。即便这么作了，还是不行。
A.    园艺初学者，不能好好照顾花，所以很灰心，不会再买花了。——无关
B.    卖稀有野花的卖花人没有更加合理的省钱方式来直接为园艺初学者提供货。
C.    稀有野花的需求数量基本不超过这花在野外能被卖花人菜的数量。也就是能收集到的数量大于稀有野花的需求数量。
D.    野花的繁殖靠这花和别的有机物的共同作用。——无关，
E.    卖野花的钱能支持发现新的低成本技术来让野花人工培育。

你的答案没错，削弱是E，加强是B
