rule of past-perfect tense is -
if there are two events in the past A and B, if we use past perfect tense event A must end when event B interrupts it.

So OA will be D

The correct answer is option D. This is Q77 in OG 2015.

Not sure if the OA is right.

Option D uses "are" which means that municipalities are still dumping, which is not stated anywhere.

That is correct muncipalities are still dumping, just that the quantity has reduced.
Hence the use of past perfect is not correct

Hi all

The question reads: :" A 1972 agreement between Canada and the United states reduced the amount of phosphates that municipalities had been allowed to dump into the Great Lakes.

I have managed to narrow down the options to two:

A) reduced the amount of phosphates that municipalities had been allowed to dump
D) reduced the amount of phosphates that municipalities are allowed to dump

The correct answer is D, but I am trying to understand what is wrong with A. Ideally, the first sentence should read "reduced the amount of phosphates that municipalities were allowed to dump" if the reduction happened in the past. But then what does "had been allowed to dump" imply and why is this the wrong answer?

Thanks

A is wrong cause -
rule of past-perfect tense is -
if there are two events in the past A and B, if we use past perfect tense event A must end when event B interrupts it.

Had been allowed to dump if the municipality was no longer allowed to dump

A 1972 agreement between Canada and the United States reduced the amount of phosphates that municipalities had been allowed to dump into the Great Lakes.

(A) reduced the amount of phosphates that municipalities had been allowed to dump
--> How to reduce amount of phosphate already dumped in past. Incorrect
(B) reduced the phosphate amount that municipalities had been dumping
Phosphate amount Should be Amount of phosphate : Incorrect
(C) reduces the phosphate amount municipalities have been allowed to dump
Same As B
(D) reduced the amount of phosphates that municipalities are allowed to dump
Correct
(E) reduces the amount of phosphates allowed for dumping by municipalities
Incorrect

A 1972 agreement between Canada and the United States reduced the amount of phosphates that municipalities had been allowed to dump into the Great Lakes.

(A) reduced the amount of phosphates that municipalities had been allowed to dump
(B) reduced the phosphate amount that municipalities had been dumping
(C) reduces the phosphate amount municipalities have been allowed to dump
(D) reduced the amount of phosphates that municipalities are allowed to dump
(E) reduces the amount of phosphates allowed for dumping by municipalities[/quote]

Between A and D, I choose D. As question speaks of an "agreement" between two countries, in D "municipalities are allowed to dump" appears more like a clause that we see usually in any formal agreement as opposed to in A "municipalities had been allowed to dump".
