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
Pl review my analysis
Agreement to reduce the amt of phosphate that was allowed to be dumped
1) A 1972 agreement between Canada and the United
States reduced the amount of phosphates
2) that municipalities had been allowed to dump into the
municipalities...had been allowed
into the Great Lakes...is correctly placed
B/w C and the US...correct
Here though even after the agreement municipalities will dump the waste (of reduced amt) the sequence is
Municipalities allowed to dump waste --->Agreement to reduce waste----> Municipalities allowed to dump less waste
POE A correct
As per the sequence it is correct to state that municipalities had been allowed, because agreement happened later
So why is D correct here?
Also, what is the difference in amt of phosphate
and phosphate amount
As I explained in my post above, according to the intended meaning of the sentence, the agreement can only reduce the amount of phosphates that can be dumped AFTER the agreement is made. "Had been dumped" refers to the amount that was dumped BEFORE the agreement was made. So, logically, it doesn't make sense to say that the agreement can reduce this amount. The correct answer must use either the simple past tense or the present tense.
There is no real difference in meaning between "amount of phosphates" and "phosphate amount", but idiomatically, we use "number of" and "amount of". So, "amount of phosphates" is better.
I hope this helps with your doubts.
