[讨论]请教一道LSAT

Cafeteria patron: The apples sold in this cafeteria are greasy. The cashier told me that the apples are in that condition when they are delivered to the cafeteria and that the cafeteria does not wash the apples it sells. Most fruit is sprayed with dangerous pesticides before it is harvested, and is dangerous until it is washed. Clearly, the cafeteria is selling pesticides-covered fruit, thereby endangering its pateons.
Which one of the following is assumption on which the argument depends?
(A)The apples that the cafeteria sells are not thoroughly washed after harvest but before reaching the cafeteria.
(B) Most pesticides that are sprayed on fruit before harvest leave a greasy residue on the fruit.
我怎么想都觉得应该选（B），不知各位的意见如何？请不吝赐教，致谢！

题目有点迷惑，但是还是清晰的，建议看清选项

文中的推理是：苹果收获时上面有残余的农药+快餐店没有洗>苹果是危险的，明显缺乏的一个gap是收获后到快餐店里的过程中有没有洗过。如果觉得B迷惑，用选项取非进行判断，一目了然（文中推理取消第一句话完全不影响）。

这道题应该是最简单的assumption题了，有一定基础的朋友看完提干就应该可以大致推理出答案，楼主要加油的说。（方法参阅置顶帖子）
