标题: 问一道GWD题我怎么觉得答案是错的？大家看一下啊

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?

A. At least one of the shipments sent to Truax Construction 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 Truax Construction 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 Truax Construction.

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

Answer: B(E)

我选了B 答案是E

可是我想要是E也不对啊，万一星期四出去的船也全是building 的那不是原文结论就不成立了啊？

星期四出去的船是全是BUILDING SUPPLIES,但文章并没有说，所有的special ordered 的船都是开往Truax Construction .所以B肯定不对，A、C与原题目无关，解释不了最后的结果。只有E，所有的special ordered 船都是Friday 开的，因而非周五的船，一定不是special ordered，当然也不会是building supplies，能够合理解释结果。
