我又看了一眼，我觉得可能是因为：
Thus, a move north would be seen as advantageous to a group that was already urbanized and steadily employed, and the easy conclusion tying their subsequent economic problems in the North to their rural background (60) comes into question.

注意：the easy conclusion不是主语，应为如果tying是直接谓语的话，应该是tyings.所以，tying their subsequent economic problems in the North to their rural background (60) comes into question.”只是“the easy conclusion” 的定语从句。这样的话，“the easy conclusion tying their subsequent economic problems in the North to their rural background (60) comes into question.”就不是一个句子，而是一个名词了。所以，the easy conclusion不应该指代“a move north would be seen as advantageous to a group that was already urbanized and steadily employed”。

由此看来：

这句话是平行结构，　ａ　ｍｏｖｅ　ｎｏｒｔｈ　ｗｏｕｌｄ　ｂｅ　ｓｅｅｎ　ａｓ：（１）advantageous
　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　（２）the easy conclusion
然后呢，the easy conclusion后面加的是定语，easy conclusion　（ｗｈｉｃｈ　ｉｓ） tying their subsequent economic　problems in the North to their rural background　(60) comes into question.

这道题不能选A

然后呢~the conclusion 究竟指的什么涅？
请看前文“This assumption has led to
the conclusion that the migrants' subsequent lack
of economic mobility in the North is tied to rural
background, a background that implies unfamiliarity
(20) with urban living and a lack of industrial skills.
”

这个easy conclusion 指的是第一段最后一句说的内容，“the conclusion that the migrants’ subsequent lack of economic mobility in the North is tied to rural background, a background that implies unfamiliarity with urban living and a lack of industrial skills”.大意是说：农村人没法在城市里混，理由是他们不熟悉城市生活和缺乏工业技能。

C是正确的。文章其实就是从这个assumption来展开的，作者的反驳思路是这样的：大批南方农村黑人进城——》导致南方城市工作竞争加剧——》原先已经在南方城市里工作的黑人（当然有一手技能）被迫到北方城市寻找机会——》得出前面的结论有问题。可以这样理解驳斥的逻辑，你不是说说农村黑人一没技能二不熟悉环境没法在城里混吗，那我现在证明来的不是南方农村黑人，而是南方城市黑人，他们既熟悉城市生活又有一手技能，所以说你这个理由不对。作者当然要同意C说的assumption才能使这个驳斥的过程完整。

还是不解

如果说“easy conclusion”是指“the conclusion that the migrants’ subsequent lack of economic mobility in the North is tied to rural background, a background that implies unfamiliarity with urban living and a lack of industrial skills”.，然而题目中问的是这个conclusion 是基于哪个assumption，而(C) “People with rural backgrounds are less likely succeed economicallyin cities than are those with urban backgrounds.”好像是对这个conclusion的概括解释吧？注意题目中问的是，这个conclusion是基于哪个assumption，而C的解答等于是把conclusion重复一遍。是我理解有错，还是因为这个事gmat的出题风格而我的思路和gmac不一致呢？
