IMO A.
B. the pronoun they is confusing.
C. comparison between monatries and a library. so incorrect.
D. Here the modifier "while clearly less accessible to outsiders" seems to indicate libraries. So incorrect.
E. wordy and improper.. Acted is some what unconvincing.

Down to A,D.
in D it is not clear whether 'while clearly less accessible to outsiders' is modifying libraries or monasteries.
A is clear compared to D.
So A is the ans,.

(E)amount of research has proven unsuccessful into the cause of acoustic
neuromas
IMO B.
Here "amount" is singular. So we are left with B,D,E.
Take D.. this is easy to eliminate
E. This is incorrect, because the prepositional phrase "into the cause of acoustic neuromas" should occur before verb has. ( there is a rule for this .. i will surf the net and post it)
So imo B. whats the OA anyway.

(A)amount of research into the cause of acoustic neuromas have proven unsuccessful
violates subj-verb agreement.
(B)amount of research into the cause of acoustic neuromas has proven unsuccessful
(C)quantity of research into the cause of acoustic neuromas have proven to be unsuccessful
violates subj-verb agreement.
(D)cause research into acoustic neuromas has proven unsuccessful
incomplete
(E)amount of research has proven unsuccessful into the cause of acoustic
neuromas
down to B,E.
E has awkward construction.
B is better.

Hi Guys,
What I inferred from your doubt and his answer is pick for singular/plural.
has----> always stands for singular.
have---> always stands for plural.
Based on these rules one can eliminate those three options.
Cheers !

a) correct answer
b) "Extensive amount" = Plural; "Has" = Singular
c) Usage of quantity for "research"

the extensive effort(s) put in for GMAT has paid rich dividends...blah blah ( usage of extensive may not be correct )
here whatever/how much ever be the effort ...it is put in for a single aim i.e. GMAT.. hence singular ...
hope i am correct
Darn... looks like I goofed up with "Amount" & "has" ....
However, Is "amount" always singular or does it depends on contextual usage ?

Hi Folks,
Most of you were correct.
OA is A
Option-B: Incorrect based on misplaced-modifier.
Option-C,D,E: Incorrect and awkward as most of you judged it.
Cheers!

Hi,
OA is B.
We deal with the noun amount, but here it's the subject of the first part of the sentence. Since amount is singular, the verb needs to be has been, so you can eliminate (A) and (C). Amount of research is better than cause research (which makes no sense at any rate), leaving you with (B) and (E). (E) creates a misplaced modifier, so (B) is the correct choice.
Cheers !

@ Papa Ji ... Would the usage of "an extensive research" add to the reason that "amount " singular ?
Just curious.

Just curious.
My apologies ...I could not understand the question clearly.
Did you mean that usage of an extensive research will be singular?
If so,you are right ...
In an extensive study/research the scientists came to the conclusion that earth revolves around the sun.
