方案推理。A方案的CQ1可行性问题，BDE与方案无关，C加强

错选了B，B是削弱了石化行业官方人员的说法。

方案推理 goal-- improve response rate ; method-- target marketing 问加强 错误B： 并没有说明这些公司的成功是因为定向投放， 也没说投放效果 正确 E： E 取非后 target marketing并不会提高response rate 所以无用（削弱）

B选项说成功公司已经开始这样投放广告了，但并不能说明这种广告策略是成功的，成功不一定是因为广告。 D选项其实是提出了另外一个方案，和本方案的定制型邮件策略无关

lend themselves to没理解

理解句意啊，不能只烤靠找平行关系，人句意里面就无关平行

lift是解除，没理解这个词整道题都做不了。

题目问的是生产商的利益，生产商的利润和客户无关，只和零售商有关。所以C选项肯定错。

求求求

没注意unlike这个词，也就没注意有比较关系，没找比较的事物。

做错的原因是找错加强点。题干要加强的不是地震这个点，而是年代这个点。B选项，没有挖掘出AD365之后的硬币，但是挖掘出了很多AD365之前的硬币，证明这个地方确实是在AD365消失了。

这道题核心的逻辑是什么呀？
公司计划扩大生产和继续广告，为哪个选项会削弱这项计划。
然后E选项说即便价格下降了，销量也仍然下降了，然后呢？没有理解这个逻辑....

Correct. four times as likely as和four times more likely than都是可以的，且含义相同。

思路不在一个频道上= =B选项我想的是题目又没有说事故的类型，属于无关项，然后选了D，认为如果一个人身上发生了多起事故，公司按人头算的话只算一起，这就削弱了题干了。感觉CR真的婆说婆有理公说公有理

补充一个Ron写的关于时态的点： In C, you forgot what may be the most straightforward means of elimination -- namely, verb tense. (Can't use "have inspired" for something that happened at a distinct point over 150 years ago.)

A里面的be capable of detection也有问题。Ron：As a writer, I wouldn't use "capable" unless I were describing the potential abilities or results of the thing that's modified by "capable".
Ordinarily, that's going to be a person or animal, since people and animals are normally the agents of most actions. It is possible, though, to speak of the "capabilities" of an inanimate object, e.g., A single atomic bomb is capable of destroying an entire metropolitan area.

In the choices you're citing here, the principal issue with "capable" is that we're not describing a "capability" of the drops themselves; rather, we're describing a capability of humans. (Humans are capable of detecting xxxx.)

"So as" should be followed by to + verb. It expresses the ultimate purpose of some action, usually indirectly or in potential terms.
I purchased a ladder, so as to be able to reach the highest shelves.
(Note the indirect relationship: Buying a ladder does not directly let one reach higher. First, one must actually take the ladder home, put it on the ground, and climb onto it.)

"So as to" is somewhat weird. It's not actually wrong, but I don't think GMAC would include it in an incorrect answer.
(This is not the same as so + (adjective) + as to + (verb), which is a common construction: Some of these feats are so difficult as to be nearly impossible even for the world's most accomplished athletes.

"So that" is followed by a complete sentence, expressing the purpose of something. Its meaning is a lot like that of "so as to".
Jimmy bought a ladder so that he could reach the top shelves.

Official Answer:
Idiom; Logical predication
The sentence describes the Ptoiemys' objective in founding a library as a location where Greek literature could be gathered together and systematized. The correct version of the sentence makes this locational importance clear.
A. The connector so as is imprecise and unidiomatic. The correct expression would be so that.
B. Correct. A library is a location, and the phrase in which is consistent with this meaning.
C. The additive conjunction and does not accurately describe the relationship between the library and the gathering and systematizing of literature.
D. Whereby indicates that the library is a means of gathering and systematizing, instead of a place where this happens.
E. By which indicates that the library is an agent of gathering and systematizing, which makes no sense.
The correct answer is B.

being现在时态没必要

B选项值得仔细想想直接表达和用抽象名词+后面解释表转折二者的区别
