(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

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”

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______。

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

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

S用进口油，gas产多于用，想从oil转gas。则对进口燃料的需求少。

达到的目标：1）unnecessary的手术减少了。2）necessary的手术没有减少。
b选项说误判的情况都是把没病的人判断成为弄成有病了，也就是说导致了unnecesary的情况，所以误判的情况全部都是unnecessary（没病说成有病）,所以necessary的都没有被判错，所有有病的人都被判断出来了，因此2）条件成立了，然后看到原文说之前是20%误判unnecessary，现在变成了2%误判unnecessary，所以1）条件也成立，unnecessary的手术减少了。

只有so/such…that没有enough that
