900个学生，30个学生一个班，得出一共30个班；30个班每个班每天6课时，一天一共180课时；180课时，每个老师教5课时，所以如果同一天的课全都有教师上，至少要要180/5=36个教师一天。

看见了than，找平行。
A：than political opposition is， is有没有相对应的be动词对应，没有，直接排除
B, C, E：to the nuclear industry than political opposition, 有歧义。
Financial uncertainties prove more deterring to the nuclear industry than financial uncertainties prove deterring to political opposition
还是Financial uncertainties prove more deterring to the nuclear industry than political opposition prove deterring to the nuclear industry
D： than is political opposition， is和前面的be对应，平行。所以对。

"asks" does not require "do" or "does". Eliminate A, C and E.

Between B and D, D contains two errors. "have a preferred status to another", here another cannot be used as a pronoun so it does not properly complete the comparison. Also "in theory" should contain a "which" before it because "which" will refer directly to the noun right before it, namely the courts.

Answer would then be B.

(A) were no Jane Austens or Brontë sisters ("were" works with both items because they're both plural)
(C) was not Jane Austen nor the Brontë sisters (singular "was" doesn't work with plural "sisters")
We can eliminate options C, D, & E because they use a singular verb with the plural Brontë sisters.
There were no Xs or Ys = CORRECT
There were not Xs or Ys = INCORRECT

from to对
despite , still 错

笑死了看评论哈哈哈哈，每道题都是我擦wcnm哈哈哈哈哈哈哈

C. a situation, which was quite tense, by stating publicly that Smith was not responsible for the debacle

This is INCORRECT because the addition of "which" turns this phrase into a non-essential modifier. This sentence tells us that the phrase "which was quite tense" isn't important information to the overall meaning of the sentence

AE区分，首先要知道后半句是在修饰前半句的“人体工程学”
B: 三个并列，错误
C：同B
D: more rather than 无该用法
E: More than 对比不对称

控制力强的动词包括但不仅限于：make，cause，force，order，allow，require，ask（要求）等等。
控制力弱的动词包括但不仅限于：indicate，know，explain，show，reveal，think，ask（询问）等等。

study和Tawahka， 表示答案在最后两句
亲属关系比合法财产权是一个更重要的指标，因此研究人员通过一个家庭在该村的居住时间对其进行了衡量。 他们发现，更长的居住时间与更多采用改良植物品种而减少采用化学除草剂有关。

as much as = non-countable nouns & percentages
That pair of shoes costs as much as my last month's rent!
The failure rate for this class can be as much as 25 percent.
as many as = countable nouns
There will be as many as 250 people at our graduation party.
My coworkers work as many as 15 percent more hours than I do each week.
We can eliminate options A, C, & D because they don't use the correct "as many as" to refer to "hours," which are countable.

B. as many as 20 percent more hours per month as pilots at larger airlines, and
This is INCORRECT for a couple reasons. First, when comparing two items, we must use "X is more than Y," and not "X is more as Y." Second, the comparisons aren't parallel. This sentence compares the hours pilots at smaller carriers fly to pilots at larger airlines. Comparing hours flown to pilots isn't parallel - we must compare hours to hours!

坑爹啊。。。。。2m+3n=55只有一种整数解

if this is an official problem, then i guess the issue boils down to the fact that the incorrect answer (c) is substantially more wordy than the correct answer (a).
i don't see anything strictly ungrammatical in (c).

L的作者不详，因为证据不足。最近，新证据出现，但仍不能证明，因为______。
A/B/C/E 都是在描述总体treatises的情况，但题中涉及的只是部分新以L命名的treatises

若将for long overdue in recognition of their outstanding bravery不加逗号地直接放在the nation’s highest military award身后，则其看起来是介词短语就近修饰名词award，整个部分皆作the Congressional Medal of Honor的同位语（即，the nation’s highest military award for long-overdue recognition of their outstanding bravery是the Congressional Medal of Honor的同位语），这是不符合逻辑的，同位语表示解释说明，若这么表达，则其表示the Congressional Medal of Honor是专门为表彰这些士兵的勇敢而设立的最高军事奖。在逻辑上，应该是士兵们被授予这个奖，目的是为了表彰他们的勇敢

between …and排除DE

①"natural selection operates" 复数
②one...another...固定搭配

among倒装，主语应该是the rate，所以应该用单数is
on earth 放置句首修饰整个句子，不符合逻辑，这里修饰动词believe是不对的
