and that 平行

读句义知道是根据women 半退休和全退休的一个比较。所以根据比较两边必须平行的原则，应该是women who took new jobs xxx more than women who retired completely,后半段必须是women who xxx，因为前半段是women who took
A．when retiring,而左边没有这个平行的结构
B．出现了if从句，可是左边么有if从句
C．Those (指代women正确) who retired，正确！
D/E.都是which was的结构，错误！因为：读句义这里应该是独主结构修饰整个句子，而which不能修饰前面的整句，which这么放着只能修饰前置词satisfaction, 逻辑意思有误
根据曼哈顿的书P230的解释，DO SO可以指代entire action, 也就是do sth adv。这里我觉得是指代reported high marital satisfaction。但是我觉得这个so不是此题的考点，而是比较平行的结构才是考点。如果仅仅用so来做判断的话，可能会掉入GMAC其他题目的陷阱

全空难道不可以算一种情况吗...

还原成标准斜率方程y=4/3X+5.
x-intercept of the line 就是求当y=0时X的值， y-intercept道理一样

the slope of line k and the other line are the same since the two lines are parallel, and thus m= 1 - m, and therefore m= 1/2. 平行代表斜率一样

代入法的时候不要忘记考虑-1，0，1这个区间。 郁闷

学生总数T： A=15%T ； M=10%T ； R为什么课都没选的
条件1： 选了A又选T的是 2/3A 所以选R=T-A-M-2/3A 代入就行了

In case we serve 1 of each 6C1*2C1=6*2=12
In case we serve 2 of each 6C2*2C2=15*1=15
=> 15+12=27

好吧，是两两互相不超过0.1，看成等比数列了……………………

错选B，脑补得太多，以为病人无任何缘由只是直接来任性找医生开药得话，医生也不会诊断病人的情况需要啥药，也就没法拒绝病人直接的要求了。。。。

错了……

代词it的指代对象只能是单数名词，不能指代句子。在逻辑上，were not successful at的对象应该是整个复制的行为，而不是某一个单数名词
其次这个it 也是多余的，应该是同位语从句中,that后面的it多余了。
实际上，C选项可以分解成两个小分句：1.an achievement that other Scandinavian kings attempted later in the century to repeat; 2. an achievement that other Scandinavian kings were not successful at it . 很明显，第2个小分句中的it其实多余了，因为已经有先行词achievement了。

是密码，所以顺序是有关的， 应该用P而不用C

如果选C，that this robe depicted scenes of a battle between Zeus, Athena's father, and giants的先行词只能是robe，又重复又不通顺。
D中，that this robe depicted scenes of a battle between Zeus, Athena's father, and giants和that each year young Athenian women collaborated to weave a new woolen robe ……平行，是indicate that的意思

AB 虽然都是修饰语但是修饰的内容不同，A表示有余额的账户，B 选项表示有低于既定标准余额的账户，对比之下B 选项更好，当然可以直接根据A 选项的时态问题排除A
CDE的that 和those均没有指代

The problem with C, though, is the last part of the answer choice: 'that they used to dress.' All this means FOR SURE is that the robe was just a tool that the women used in the process of dressing the statue (maybe they used it to zip up the back of the statue's dress...??). Choice D, on the other hand, correctly conveys the idea that the women actually put the dress ON the statue.

用助动词代表前面的动词时，要注意时态一致；如果时态不一致时，要重复前面的动词如

Wrong: I have never seen an aardvark, but last year my father DID. 动词have seen与助动词did时态不一致，应该改为

Right: I have never seen an aardvark, but last year my father SAW one.

B选项show n. to do 语义错误，意思是展示化合物去干什么，不正确
