请大家来看看本月逻辑的一道机经题

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, 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. 这跟杂志推不推销没关系
(B) Plant sellers who sell rare wildflowers have no reasonably inexpensive alternate way to offer their wares directly to new gardens. 就因为野花的卖家没有其他更便宜的途径向买家推销野花，所以野花的销售数量会减少
(C) The demand for rare wildflowers rarely exceeds the number of such plants that can be collected in the wild by plant sellers. 这跟杂志推不推销没关系，野花的数量不会受到威胁
(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.偏题
(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.这是反对杂志的新措施

个人觉得应该选B. 原因如下.

题目是说买家由于看了杂志，所以时常按杂志说推销的花类来购买。该杂志为了保护野花的生存，所以决定不再推销野花。题目是问哪一项能够支持该杂志的新措施。

我一直以为B是说不可能卖得便宜。。汗。。
如果是说没有其他更便宜的途径的话，那B就很对了~

越说越乱。 但感觉如果B不成立，也就是说SLLER还有除了杂志宣传外的其他途径销售，那么杂志取消宣传就没多大作用了（会削弱结论）。而C不成立，好像没什么直接影响。

应该是B。支持题里也会有假设题的答案的。

C项说了与题干条件可能冲突的情况。题干中野花的威胁存在已经是事实了，C项情况可能结果是威胁存在，也可能不存在。

GMAT逻辑中很常见选项内容重复或矛盾题干。

答案是B, 已经是确定了的.

因为杂志不再提供野花的宣传, 而卖野花的又找不到其它地方去宣传野花, 而新的买花的因为看不到卖野花的宣传, 就不会去买野花了.

C...
问的是支持 C就是杂志社采取那个措施的原因.. 就是支持了原文杂志社的做法。

okay, 是我翻译的有点过激了，同意szfifizheng的说法。是几乎不会超过

szfifizheng

应该是几乎不可能超过，不是远远低于。。

原来晚上那么多人不睡啊...
还是说都在国外...
简单来说B提到了贵不贵，是个无关于原文的东西，你这个东西贵不贵跟用不用在GMAC看来还差着远呢...
C说野外的量不能满足需求，是不是直接就表明了会对花造成危害阿...所以杂志的措施才有意义啊...

(C) The demand for rare wildflowers rarely exceedsthe number of such plants that can be collected in the wild by plant sellers.

你是不是看错了？C是说对野花的需求远远低于供应
