c v.s. e

d——十分纠结的不相关答案

c两个点错了：
1.to rate 改为for rating
！！2.当rate宾语从句时，宾语从句中的核心词是collide，而真正应该做rate宾语的是likelihood，

c错：稳重并没提到tech从属于productivity improvement之下/的影响因素之一（未表明二者层面上游河关系），因此c说pi集中于。。属于将话题拉倒了不相关的层面

a定语从句解析：
定语从句 that scientists hope will enable them to understand how the solar system formed some four billion years ago是一个嵌入式关系分句，将先行词和省略部分代入其中，则有：
scientists hope (that) measurements will enable them to understand how the solar system formed some four billion years ago.

C D 虽然可以用被动语态解释，但检讨下来感觉用未画线部分排除选项更快一点，因为and身后是genetic variation（名词），所以身前应该也要是名词，故C D去掉

我靠 我一大段都没看见。。。

毕老师的答案哦，有时候让我就是觉得是看着答案写解释，你知道了答案你就编怎么对就好了

看到别的论坛的解体方法：
1- 识别出是平行结构先
然后就比较好判断了

D & E 算两个东西，所以用Have

平行结构，平行结构，平行结构。

问的是members of tailor's guild

。。。因为A太明显把A排掉了..想着不会这么简单吧。弯弯绕绕选了D...真是画蛇添足

偷懒了，没有回头看。

Increases 是复数！！

They 指代谁很模糊，这个GMAT经常考，代指的问题
spectuation 是指整个clause

这个图真是厉害了，GMAT真是不能看图

看错了第一句话
1. The slope of line l is 3 times its y-intercept

斜率是y轴交点的三倍。

• B：(b) contains bad parallelism. since you're talking about two trends that have taken place simultaneously, you MUST use the same verb tense to describe those trends.
in (b), the first verb (has ... added) is in the present perfect, but the second (increased) is in the simple past. the parallelism in (a) is perfect: both verbs (has ... added and have ... increased) are presented in the same tense.
• C：many new restaurants have recently been opened across the country and...
in this construction, there is no indication that these new restaurants have been opened by the company in question. it just says that they have recently been opened, but not by whom. that's an unacceptable shift of meaning.
• D&E：these choices are both wrong for one of the most common (and therefore important) reasons you'll encounter: the initial modifier modifies the wrong noun. both of these choices modify "the restaurant company's sales". they should be modifying "the restaurant company".

老师 请问
According to a 1996 study published in the Journal of Human Resources, Americans of Middle Eastern descent were twice as likely as was the national average to be self-employed.

这句话里面，这一部分Americans of Middle Eastern descent是做主语，那其中核心词是amrcians还是descent呢？我觉得应该是americans，但是视频里说的是descent。

另外，像 the majority of students, 核心词是students还是majority呢？谢谢

平方之后会变为正数。。。。。。
