I think is C. In A, B, D - "their" is ambiguous, and E sounds wordy.

patients will be referred by "who" not "which".

In D) what does "their" refer to. I would prefer E) over D) although E) is lengthy.

1. In large doses, analgesics that work in the brain as antagonists to certain chemicals have caused psychological disturbances in patients, which may limit their potential to relieve severe pain.
(A) which may limit their potential to relieve
Their : does it refer to Analgesics or Chemicals??
(B) which may limit their potential for relieving
Their : does it refer to Analgesics or Chemicals??
(C) which may limit such analgesics’ potential to relieve
Which is a non restrictive clause, thuse the statement will still be correct if the entire sentence fragment is removed from the sentence. i.e "which may limit their potential to relieve severe pain.".
This is the correct option IMO
(D) an effect that may limit their potential to relieve
Their : does it refer to Analgesics or Chemicals??
(E) an effect that may limit the potential of such analgesics for relieving
for relieving is awkward

here is what i think :

A,B,D have "their" which is ambiguous

C is good as it has "to relieve " which sounds much better than "for relieving" in E

I agree that in E which is replaced by "an effect" which sounds more clear but at the same time it makes it wordy esp when "which"
clearly indicates "caused psychological disturbances in patients"

'potential to' is the correct idiom usage.

Hey ashwin,
I got some idiom notes but yes in those notes its written potential to is correct but somehow i remember a question in 1000SC which says potential for is the correct usage

Actually correct me if im wrong :
Whenever we use POTENTIAL as a noun ,we need to use FOR
actually even potential to is valid like we say :
A graduate of a top business school has the potential to make over \$100,000.

But here in the given question if we use potential to then it misleads
us saying that LIMITING THE POTENTIAL to relieve THE PAIN

but actually author means here POTENTIAL FOR relieving IS LIMITED

consider this example :
Despite its attractiveness, investing abroad can still pose big risks, ranging from the potential for political instability in some countries to the shortage of regulations to protect investors and a serious lack of information about investments in others

we can take the analogy of ability and CAPABILITY

he has the capability for painting well
he has the ability to paint well

Kindly let me know if any additional info on this

Between C and E, its straight C, reason E.. an effect(to quote physcological distrubances) which is wrong.
Besides C is concise.

1. In large doses, analgesics that work in the brain as antagonists to certain chemicals have caused psychological disturbances in patients, which may limit their potential to relieve severe pain.

(A) which may limit their potential to relieve
-- "which" illogically mdofiies patients.

(B) which may limit their potential for relieving
-- "which" illogically mdofiies patients.

(C) which may limit such analgesics’ potential to relieve
-- "which" illogically mdofiies patients.

(D) an effect that may limit their potential to relieve
-- "their" illogically refers to the pronoun of patients.

(E) an effect that may limit the potential of such analgesics for relieving
>>Correct

"Which may limit" is wrong. What may limit? Patients? Psychological disurbances? Antagonists? Certain chemicals? The effect?

D is wrong. Pronoun usage is unclear. "Their" refers to what? Patients? Psychological disurbances? Antagonists? Certain chemicals?

E for clarity.

i guess C.
A,B,D implies the "pateints potenital" and not the "drugs potential".
E is wordy.

B/W D and E as A,B,C have the "which" problem.

D. "their" could refer to patients or alangesics and hence I belive is a big flaw
E. Even though it may sound ackward, grammatically I do not see anything worng with it;
Can anyone who have answered D offer a more convincing argument as to why "reliving it" may be wrong in E

Hey Priya,

I feel the example you used is not correct. Potential is similar in meaning to ability.

Despite its attractiveness, investing abroad can still pose big risks, ranging from the potential for political instability in some countries to the shortage of regulations to protect investors and a serious lack of information about investments in others

To correct the problem

We need to change 'potential for' to 'potential to cause'

Hence

Despite its attractiveness, investing abroad can still pose big risks, ranging from the potential to cause political instability in some countries to the shortage of regulations to protect investors and a serious lack of information about investments in others

Now the comparison falls in place.

Please remember in GMAT, always 'potential to' is considered accurate.

FOR ME, E is better than D. D has clearly antecedent/pronoun problem that E doesnot have, however E is wordy.

I bet on E.

Logically the sentence wanted to describe an effect of X function as Y: D/E are better candidates than others.

“Which” incorrectly points to patients instead it is intended to “analgesics” - Eliminate A, B and C

D: their – can point to analgesics, psychological disturbances and patients

Not going to go too crazy out on a limb here, but I think it is best the way it was. the which is clearly referring to the psychological problems, because which can only modify a thing (not a person), that starts a clause that is unnecessary to form a complete thought (that would be used if it was necessary); therefore, it is not ambiguous at all here. the their may appear ambiguous, but it has to refer to the subject of the sentence, the analgesics. the other choices just add unnecessary words. also, you never want to repeat technical words in one sentence (it is almost always inefficient), you want to use pronouns if you can. Option A contains all the information, is grammatically correct, and is the most concise.
