语法大全很少错的，印象里好像就出现过一两个错误。这题确实比较难。

Since the dumping continued after the date of the agreement, the past perfect verb had been allowed
should instead be the present are allowed (if the agreement remained in effect when the sentence was written) or the past were allowed (if the agreement was no longer in effect when the sentence was written).
