标题: 再问987-2, og11-62

1. 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

(D) reduced the amount of phosphates that municipalities are allowed to dump

(E) reduces the amount of phosphates allowed for dumping by municipalities

og上给的答案是D,在讨论区看了好几个帖子才接受了现在时，但现在987里面答案却给了A,难道是og答案被推翻了？

请达人指教,xiexie !

我也发现了这个矛盾，总的来说OG给的答案不太可能错，难道是大全是错的？

如果这样，大全的答案可靠吗？对大全有点怀疑了

牛牛们给解释一下啊
