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.

答案不知有b有e，我不明白意思，请指教！！！

应该是E.
题干：
*5个特定的shipment是星期四送走的。
*所有星期五送走的shipment都是建房用的（数量偶们不知）
*送到T建筑公司的共有4个shipments,其中3个是建房shipment.
从上可以推出，剩下的一个shipment不是星期五送的，那必定是星期一，二，三或四送的，（题干说了周末没有办公），所以就是E 啦。而B 如果不是否定，是肯定的话也有可能对。但是E是肯定可以推出来的。mm 想想，对吗？
