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.
At least one of the shipments sent to Truax Construction last week was sent out before Friday.
题目说了星期四送了什么，星期五送了什么，但没说一周里其他天是关了的啊。所以做保真推理，B是推理不出来的；E是写的很好的选项，写was sent out before Friday, 但没说哪一天
列个表出来就知道了
Thurs - the 5 specially ordered shipments
Fri - all building materials
TC - 4 loads, 3 of them building supplies
上周四：送出的货物里含5个特殊order（没提是否还有其他货）
上周五：只送建材 周六周日停止
TC收到的四个货里有三个是建材=三个是上周五收到的，一个不是上周五收到的
A 剩下的那个不一定是特殊订单。可能是周一周二送的，可能是周四送的其他
B 文中没说周四送的是否包括建材
C 同B文中没说周四送的是否包括建材，周四也有可能送建材
D 同B 建材不一定是周五发的
所有的special都是周四寄出，周五寄出的都是building supplier，周末关门。
TC公司收到4个包裹，（只有）3个是building supplier
那么一定有一个不是building supplier，也就不是在周五寄出，因为周末关门，只能在周五前寄出
