premise：新的在museum外的执照费很贵
如果Charging typical prices，这里的price是指pretzel的price，而不是license的（因为是vendor charging啊，如果是license fee的话应该就是charged了吧），就是说如果售价不变，那么在博物馆外要卖25个break even，在city hall外卖15个回本
所以在售价不变的情况下，license fee涨了，就得卖的更多（ E:买的人更多）才能回本，反过来说就是没人买就更回不了本
conclusion：在museum外赚不回来钱

没懂a在说什么······

请问A和C里面的it指代的是什么呀，是efficiency还是improved efficiency？

D的to make的逻辑主语是the computer company 所以后面的it要用反身代词itself，错了

What does make sense is, as the sentence created A conveys, that they cannot be laid off if ON AN ONGOING BASIS they have been given reason to believe that their jobs will be safe.

Additionally, B does not make sense because the conditional would is used, but no condition for what would happen is mentioned. In other words, their jobs would still be safe if what? The answer to that question is not provided. If anything the sentence created using B seems to nonsensically convey that the workers cannot be laid off if they are given reason to believe that their jobs would still be safe even though they are being laid off.

关于C选项，这里有一个帖子解释的很好：http://www.beatthegmat.com/og-most-of-the-country-s-biggest-daily-newspapers-t296090.html。
C选项省略的部分写全的话是：
Most of the country’s biggest daily newspapers had lower circulation in the six months from October 1995 through March 1996 than [they had circulation] in a similar period a year earlier.
Here, the words in brackets are omitted but implied.

此题考查的是有省略时的平行。关于D选项，如果句子中出现了that等代词，找到先行词（这里是circulation in the six months..）再带入局句子中读一下看是否合理。这里不合理。

allegiance 忠诚=loyalty

这题笑死，2周前那个问题不知道当时脑子在想啥：把BCDE主干提出来看
B。waterlogged latex balls and the painting ...attests，排除
C。waterlogged latex balls and ceramics...attests，排除
D。 the finding and the painting.....attests，排除
E。the finding of xxx and xxx和the finding of xxx and of xxx是一样的，of只是为了使平行更工整消除歧义，所以主语还是the finding，但是后面是attest，排除

根据Manhattan SC 6th, 链接两个句子的连词有七个，简称FANBOYS, 包括：For, And, Nor, But, Or, Yet, As.

usher引导，迎接。正确用法：I usher X in.或者I usher X into..
A usher in…into…不对；主句是一般将来时，从句应该用现在时态表示与主句同时发生
B usher in…into…不对

请问下老师，这里面restrict这个动作不是没有结束时间吗？为什么用名词restriction而不是restricting啊？

recognized是及物动词，后面要跟一个宾语，BCE中的recognized单飞不对

B, C, and E lack direct object to the verb recognized.

D is out since in GMAT SC, you cannot start off a sentence with but, or, or, and.

Further, D has two subjects seperated by couple of modifiers( red portion)-

文中：even old oil paint is unaffected by wide fluctuations in temperature and humidity. Therefore, museums could relax their standards and save money without endangering their Renaissance oil paintings.旧的颜料不会被温度和湿度影响，所以，保存R油画的时候可以放宽标准。
D.R油画中除了颜料，没有其他材料会因为温度或湿度易被破坏。（画中除了颜料可能还有纸啊什么乱七八糟的不会对温度和湿度敏感）

gmac老阴比

sanctuaries 庇护所

这题错选了C.除了尝试按照逻辑意思理解之外，还顺带强记了一个语法知识：介词＋名词＋动词ing形式的搭配是不对的，没有这种表达。只有当ing做定语修饰前面的名词时例外。
所以本题的C选项，要想语法正确的话，怎么也该是“by the animal's overcompensating".

A making 伴随状语 逻辑主语 incorrect
B 独立主格 it 形式宾语 不能指代 ‘that a United States citizen hold’ -kick off A/B
C 独立主格 可以表示主从句因果关系 emphasize ‘a law passed in 1933’这件事 和 主句内容 逻辑语义上不make sense
D 优于 C 是因为 emphasize 'making it a crime punishable by imprisonment for a United States citizen to hold‘这件事
E being同时性
