1.Although the manager agreed to a more flexible work schedule, he said that it must be posted on the bulletin board so that both management and labor will know what everyone is assigned to do.

(A) he said that it must be posted on the bulletin board so that both management and labor will know what everyone is

(B) he said it had to be posted on the bulletin board so that both management and labor knows what everyone is

(C) he said that they would have to post the assignments on the bulletin board so that management and labor knew what everyone was

(D) he said that the schedule would have to be posted on the bulletin board so that both management and labor would know what everyone was（A）

(E) saying that the schedule had to be posted on the bulletin board so that both management and labor would know what everyone had been

AD比较，manager是said，过去说的，为什么不能用would；还有就是A的第一个it没有指代问题吗？

1,原文中情态动词不可改变
2,类似 have to, be able to 表主观意愿，一般不选

公理之一，情态动词必须保留。因此一步必杀消灭BCDE选项

刚刚看了下CD上的相关帖子，情态动词并不是必须保留的，我觉得多GMAT来说，除了英语语法规则外，其余定理什么的都是浮云，太过绝对了
