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 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.

类型：归纳

(A) At least one of the shipments sent to TC last week was specially ordered.

(B) At least one of last week's specially ordered shipments did not consist of building supplies.

(C) At least one of the shipments sent to TC was not sent out on Thursday of last week.

(D) At least one of the shipments that were sent out on Friday of last week was sent to TC

(E) At least one of the shipments sent to TC last week was sent out before Friday.

正确答案E,我认为D 也没有错

D中说在星期五至少有one shipment，题目中说星期五发的全是building supplies 的shipments. 结论说发到TC中的4艘，只有三艘是building supplies.那么可以说至少有one shipment 是在 星期五发的。没错呀？选项很纠结！

谢谢！搞明白了，就是还有星期一到星期四这个隐含假设在里面！

D错了，因为上星期发TC的有四批货（三批是building supplies），这四批货完全可以全都是星期一到星期四送；星期五可以不送TC。
