求教GWD12-20思路

Q20:

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?

 

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

the answer is E, but I chose D, why is E correct?

上周四出5艘船,上周五出的船都有bs,周末不出船,4艘到T工地的船中有3艘有bs

结论很明显,在到T的船中,3艘有bs的船有可能是周五发出的,也可能是之前发出的,但那艘没有bs的就一定不是周五发出的,因为周五发出的船都有bs。既然它肯定不是周五发出,那就是周五以前发出的,因为周末不出船嘛。
