* "extent TO" is unidiomatic; it should be "extent OF".
* "degree THAT" doesn't work. since things happen TO a degree, you have to preserve this preposition; therefore, you have to say "degree TO WHICH".
present X Y = present Y to X
presents a problem a response = presents a response to a problem
to which the argument assesses是修饰response的
BF2就是main conclusion，not support
“a possible workshop” is a hoax: I mean, think about it. There can be “a ballet workshop,” “an acting workshop.” How can there be a “possible” workshop? Is “possible” a kind of workshop? It makes no sense. The sentence speaks of a site that was possibly a workshop.
"You are comparing actions, so you must use "just as."
Between D and E, D is not logically parallel. Remember, you are comparing the actions. You are comparing the increase in earth's rotation to the increase in speed of the skater.
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
