Because sales of cars and light trucks made in North America declined 13.6 percent in late February, many analysts concluded that evidence of a recovering automotive market remains slight.
这个我觉得有点类似og12－74 74.A 1972 agreement between Canada and the United States reduced the amount of phosphates that municipalities are allowed to dump into the Great Lakes. 主句当中使用的是reduced一般过去式，自治区被允许投放的磷酸盐的量减少发生在agreement颁布以后，所以从句的时态应该用are allowed表明这个结果到现在还存在着，或者用were allowed表明这个结果在这个句子之前已经停止作用了
