be geared to（ward） doing sth是固定搭配，表示旨在做某事。 这里的to（ward）是介词，后面要跟动名词

是否可变成“do not have, nor are likely to”?
NO. you can't do that unless you have a "neither" in front.
the schools neither have, nor are likely to have, ...this would work.

This an idiomatic construction: nor + helping verb + subject.
CONJ You use nor after a negative statement in order to introduce another negative statement which adds information to the previous one. (用于否定句后，引出另一否定句以补充前句) 也不
Cooking up a quick dish doesn't mean you have to sacrifice flavor. Nor does fast food have to be junk food.

this sentence will only make sense if the modifier is allowed to modify the preceding clause, which talks about holding water
D、E的modifiers in those choices are modifiers that modify nouns, not clauses. that's a problem in this case.
D：比较错误：(amount of water) IS MORE THAN (specific lakes)

A：More than 300 rivers drain into Siberia's Lake Baikal【, which holds 20 percent of the world's fresh water「, more than all the North American Great Lakes combined」】.
(a) you can view this correctly as a comparison involving the extent of the word "hold".
i.e., lake baikal holds ... more than all the great lakes combined. （可视为省略do：more than DO all the great lakes combined）
more than部分是appositive modifier，可以refer to a noun or to an entire clause

OG后面的答题解析解释半天，结果说the correct answer is A？！

什么是“ownership gap”。这样我们找到定位句的前一句。即“At the time, minorities constituted seventeen percent of the nation's population, but only four percent of the nation's self-employed. ”。首先找这句话中到底有什么“gap”，显然是17%，与4%的一个“gap”。用白话说，就是少数民族当老板的太少了。

【meaning】
the problem with (a) is that it says only that companies are aware "that there ARE connotations". but the companies don't necessarily know what those connotations are.
//
i am aware that discounts are available this weekend.
--> i know that there ARE discounts, but i don't necessarily know the specifics.
i am aware of the discounts available this weekend.
--> i actually know the specifics (percentages or whatever) of the discounts.

有less 就要有than，而且前文有behind 就是少于的意思了，再用less就重复了

any time 不等于 any other time .只能用any other time,否则就把now也包括进去了。

此外，A中核心比较对象是make efficient这件事情，所以要比较对等就得后面也是一件事情。DE中比较的是现在比以前可以产更多汽车，不符合题意，要比较的话也只需要用now 和in any other time 作比较就可以了

（1）n是个奇数，所以(n-1)和(n+1)是两个相邻的偶数。两个相邻的偶数，必然有一个可以被4整除、一个可以被2整除，比如2、4、6、8等等。所以(n-1)(n+1)可以被8整除。
（2）n不能被3整除，所以(n-1)和(n+1)必然有其中一个可以被3整除，比如3、4、5、6、7、8、9等等。所以(n-1)(n+1)可以被3整除。
综合上面两个条件，(n-1)(n+1)可以被24整除。

和核心推理无关的部分都才被称为是背景

为什么是关于早期历史的？通篇都是在讲领导人啊，而且开篇第一句是说"In a new book about the antiparty feeling of the early political leaders of the United States"

0.75mx=27x

因为p始终正数

没有读懂题If each dessert platter contains an equal number of kinds of cheese and kinds of fruit,，这句话没看清意思

qualify对应exception！好绝

是在下太轻敌了
