idiom: there were no X's or Y's.
(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

As in choice A, this choice suggests that the graders themselves might waste rainwater.

intact 完整的和fragment碎片化的应该是并列的关系用and
the possible site of a workshop就对了

it is hoped 表客观，ETS prefer
hopefully 表主观，GMAT中一般为错误选项
hopefully meaning "i hope that/let's hope that". This is an informal expression, and is generally avoided in writing.

原句中就出现表达有误的情况，与D相似

A may be和likely重复；emerge in别的程序，或者in采访的weeks，如果没有in的话，句子就变成了（出现在别的程序中）或者（采访的星期），括号中的两个意思不平行。
b whose不能修饰process；emerge 动词形式>名词形式，后面or前后平行同上。
c correct

is influenced是不是可以说明，这件事情现在没有完全结束，所以后面的要用the coming to an end ？

flat表示平整地，flatly表示断然地；平平地；直截了当地
flat应该是做宾语补足语吧

对and 的理解是，如果前面加了逗号，则是一个独立的、并列的完整句子。
如果没加逗号，要于前面保持平行。

smooth可以做副词， perfect是形容词， smooth and perfectly
B：wings的同位语。后半句wings后面的是做宾语从句吧？

conc：Of these, the last was likely the least affluent of the three—and most likely Edmund's father

没有仔细读题 however 之前有个转折 This hypothesis would be hard to confirm directly，否定hyp

X/4.5 + (500 - X)/3.5 = 120
不要硬解方程耽误时间，判断方程的属性（整除、奇偶数等等）来筛出选项

(300/x + 5)(x-2) = 420

be preoccupied with 专注于
be curious about 好奇
