我选A,

one day修饰compete;而不能修饰competing parnter

zhuceg

I go for A, since there is no way to understand such part of B as "as competing companies one day may be partners the next".

"the next" simply plays no role in this structure.

In A, the "as" could be seen as "because"

看看，自己做错的题目

支持选A。原意是：原来互相竞争的公司有一天会变成合作伙伴。但B改变了句意，竞争的公司会成为合作伙伴。

vote for A!

主要是B中的the next说不清楚

"Whereas" and "although" are both correct. We can't choose between A and B on the basis of these words.

The reference of the pronoun "they" is unambiguous in both A and B. It refers both logically and grammatically to the subject of the preceding clause "lines." We can't choose between A and B on the basis of this word either.

What makes B wrong is the phrase: "as competing companies one day may be partners the next." The separation of "competing" from "one day" confuses the intended meaning. In A, "companies that compete one day may be partners the next" is clear and logical.

以下是引用highdior在2008/9/15 22:57:00的发言：

one day, 是和the next(day)平行的。A中one day 存在修饰compete的岐义，因此和the next 就不平行了。

和平行结构较劲通常在GMAT里都行不通，选B。

比平行大的是逻辑

原文表达对比

B although 是让步  改变原文意思

所以 选A！！
