  能翻译下这道题目不？谢谢．．．．．答案不确定

答案A吧。我的理解：5个special，X个building supplier，得到3个bs，那肯定一个是special吧 因为只有2种 请指正

我个人觉得是E。

周四： 5个specially ordered shipments, 但不确定是什么

周五：全部是building supplies

客户上周收到4件， 3件是building supplies.

A 说至少有一件是specially ordered，那不一定，可能全部是周二ordinarily ordered

B 说至少有一件是没有building supplies, 也不一定，因为周一到周五不管是不是specially ordered,可能全部是building supplies, 而客户收到的一件不是building supplies的单子有可能不是从这家货运公司order的

C 说至少有一件不是上周四发出的，这个不一定，可以四件全部都是Specially ordered周四发出，而其中3件是building supplies - 符合客户接受到的物品情况。

D 说上周五发出的货物至少有一件发到这个客户，那不一定，因为可能是周三把4个货物全发给客户了，周五没有发任何东西。

E 说至少有一件发给这个客户的货物是周五前发的。首先判定客户的4件肯定不可能都是周五发的货，因为周五全部是building supplies, 这样的话，客户收到的这1－4件货物中必然是有1件或多件是周五前发的，甚至全部是周五前发的。

这是我的理解，请大家指教。

E is the answer

周五发出的，全部是building supplies

但是T收到的并不全是building supplies，说明这批货不是周五发的，

周四发了5个特别的shipment，但是不知道组分

所以不能确定是不是周四发的

但由于周六港口关闭不能发货

所以只有E了
