标题: 大全一题

Shipping Clerk: The five specially ordered shipments sent out last week were sent out on Thursday. Last week, all of the shipments that were sent out on Friday consisted entirely of building supplies, and the shipping department then closed for the weekend. Four shipments were sent to Truax Construction last week, only three of which consisted of building supplies.

If the shipping clerk’s statements are true, which of the following must also be true?

At least one of the shipments sent to Truax Construction last week was specially ordered.
At least one of last week’s specially ordered shipments did not consist of building supplies.
At least one of the shipments sent to Truax Construction was not sent out on Thursday of last week.
At least one of the shipments that were sent out on Friday of last week was sent to Truax Construction.

E At least one of the shipments sent to Truax Construction last week was sent out before Friday.

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
