仰天大睡的猫

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


白老师的书里写正确答案是A,OG说是D.
不知道这道问题大家有没有注意到,我在论坛上搜了好一阵子,没有相关讨论所以Post上来了.
