8. That sales can be increased by the presence of sunlight
within a store has been shown by the experience of
the only Savefast department store with a large
skylight. The skylight allows sunlight into half of the
store, reducing the need for artificial light. The rest of
the store uses only artificial light. Since the store
opened two years ago, the departments on the sunlit
side have had substantially higher sales than the other
departments.  
Which of the following, if true, most strengthens the
argument?
(A) On particularly cloudy days, more artificial light
is used to illuminate the part of the store under
the skylight.
(B) When the store is open at night, the departments
in the part of the store under the skylight have
sales that are no higher than those of other
departments.
(C) Many customers purchase items from
departments in both parts of the store on a single
shopping trip.
(D) Besides the skylight, there are several significant
architectural differences between the two parts of
the store.
(E) The departments in the part of the store under the
skylight are the departments that generally have
the highest sales in other stores in the Savefast
chain.

E选项削弱。

- - alex版主，我怎么感觉是加强了呢？
我的思路如下：
这些商店分成两个部分：一种是有只有人造的光，另一种是允许一半自然光进入这样的商店。
结论说的是那些那些有太阳光的销售量比其它的要高一些。

E选项：说的是在天空底下的商店，往往是销售量最高的商店。
这个不和原文说的是一个意思的吗？

你好，我觉得E选项的意思是那些有太阳光的销量本来就是最高的，跟有没有太阳光没有关系。是不是要注意一下generally这个词
