OA after some discussions.

I believe A.

Not since......so X that Y should be the correct idiom.

Also, has curbed make sense and not did curb. Since author is taking about indefinite time that continues.

[spoiler]is it C?[/spoiler]

we need a has here...because to show since that moment till now.
A,E looks awkward.

Should be A. What is the OA?

Thanks.

My Choice - C

An action is coming into the present, so we'll prefer has/have but here we would go with has as the subject is 'a religious organization'.

So we are now left with A,C and E.

E is obviously wrong.

Using that instead of to changes the meaning in option A.

IMO C

has is better than did here because did signifies that institution has stopped curbing the ability
where as has means the institution is still curbing the ability
so left with A,C and E.
E is absurd
ability to is the correct idiom..
correct me if wrong..thnx..

OA C
