(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(A)
(E) reduces the amount of phosphates allowed for dumping by municipalities
I personally believe that the answer is C. The 1972 agreement only can reduce the amount of phosphate be allowed to dump after 1972 not before 1972. The right tense should be present perfect.
Welcome to discuss
Thanks
I noticed that 1972 is past time but agreement is only aplicable to the future action, isn't it?
Thanks for your explanation anyway.
