possible和may重复

cease！

A支持扩张铁路的人，报告说扩张铁路的主要好处是，他们使用公路通勤时的交通更少拥挤
都想继续用公路，而让别人用railway，最后没有人做出改变，拥堵问题就不会改善

C 选项 不能用more 和 yet discovered 做比较。 因为还没有发掘的不能做比较

可以从1开始 依次此往上数 把所有的可能都列出来

本题的重点是：misleading
辐射对食物来说，会造成营养流失；烹饪对于食物来说，也会造成营养流失。
但，Irradiation是一手伤害，Cooking只能叠加伤害，两个的作用不一样，不能放在一起比较。

A和方案无关
E是方案带来的变化

写给自己复习看，棱边垂直底边，所以可以用勾股

not so much/as:
as/as即可用于肯定句，也可用于否定句；not so/ as只能用于否定句；
not so much A/as B，与其说是……，不如说是，相当于rather than。可以变形为 not so much A/but B或 not A, so much as B
not so much A/as B可以跟名词/形容词/短语/句子，要求连接对象平行。

consolidation ——merging

勉强理解E。题目说通过不给他打广告，能够减少野外花被采摘。E选项是说，有低成本的人工养殖也可以达到野外花被采摘的减少，所以不一定要通过不打广告这个方法。

文中认为，通过数量多得到晋升是不正确的，而应该通过质量晋升。问题问原文反对下面哪个，原文反对的就是通过数量晋升。E选项就是说通过数量晋升。

把第一个数字选完之后，后三位为什么不可以理解为在剩下的9个数里选出3个去填空啊？C(9,1) x C (9, 3)

首先要用geographic定位于第二段，（用1680-1880这个词在第一段找，会发现与geographic无关）。
其次找到limit这个词，是这个问题C选项的核心词。

A选项，是用第一段的内容做干扰。但是细想是与geographic无关的。

在做题时，觉得C项Bones再次出现有些没有必要。
现在再思考，发现当有一个split出现在这里的时候，要想一下bones出现是否有必要，如果省略掉了它，是否会造成混淆和歧义。
其实用bones这一点，就可以排除掉ABE了。

这道题首先定位要准确：第二段第一句。（而非第一段最后一句。）
其次，做题时没有看出来political loyalty是对political allegiance的改写；incorrectly assumed that women's party loyalty played a small role 是对underestimated the extent and significance的改写。Whig and Democratic party politics这种用后文中表示实际概念的词的出现，也是改写常用的方式。

E项错误选项设置的方式是：用第一段的话来混淆。用woman's rights movement来替换the antebellum period，而实际上两者不具备等价替换的关系。

搬运自GMATCLUB：

Split #1: "awarded" vs. "awarded with". The construction "awarded with" is idiomatically incorrect. We would just say Q was awarded the XYZ medal. (A) & (B) make this mistake and cannot be correct.

Split #2: idiom for recognition. The correct idiom here is "in recognition", not "for recognition". (B) & (D) make this mistake and cannot be correct.

That gets us down to (C) vs. (E), which is the hard part of this question. First, look at the way they both modify the name of the medal:
(C) the Congressional Medal of Honor, which was the nation’s highest military award, ...
(E) the Congressional Medal of Honor, the nation’s highest military award, ...
Choice (E) uses an appositive phrase. For more on this, see:
http://magoosh.com/gmat/2012/gmat-gramm ... e-phrases/
This structure is very elegant and concise. By contrast, the "which" clause in (C) is a little longer. There's also a problem with verb tense. I realize the tense is the same as in the prompt, but the past tense makes it sound as if that medal WAS the nation's highest military award, but isn't anymore. Is this true? Was a new highest honor recently introduced to supersede this medal? Hmmm, this calls for outside knowledge, but it just seems unlikely that whatever the highest military honor was recently (in the 1990s) would be swapped out for something else. Not only is (C) longer and clunkier, but it also raises awkward questions about verb tense & implication that (E) sleekly avoids.
Both endings are acceptable ("long-overdue in recognition" vs. "in long-overdue recognition"), because we could reasonably say that either the medal or the recognition was overdue. The above discussion indicates why (E) is a superior answer, and the best answer here.
（帖子内也有人说 awarded with 在日常刊物中也能看到，只不过GMAC不认为它正确。）

要考虑一下是否有第三因会影响结论。

最后一句话，说明影响对象是Oil paintings。C项引到了别的对象上

结论：该做的手术不会少做。
B项说明误诊的都是不该做手术的。

我错选了E。E尽管说明了被误诊的人的情况，但是没有说明是否会影响到该做手术的人。
