Comcorp Shipping Clerkast week, no shipments of building supplies were sent out on Friday.The five specially ordered shipments sent out last week were sent out on Thursday, and each of those specially ordered shipments consisted entirely of building supplies.Four shipments were sent to Truax Construction last week, none of which consisted of building supplies.
If the shipping clerk’s statements are true, which of the following must also be true?
A. All of Comcorp’s shipments of building supplies last week were specially ordered.
B. None of Comcorp’s shipments sent on Friday of last week was sent to Truax Construction.
C. None of the shipments sent by Comcorp to Truax Construction last week was specially ordered.
D. None of Comcorp’s shipments sent on Thursday of last week was sent to Truax Construction.
E. All of Comcorp’s shipments of building supplies last week were sent out on Thursday.
注意以下两点： 首先，The five specially ordered shipments，因为有定冠词the存在，所以确定上周只有5个special ordered shipments发出 and each of those specially ordered shipments consisted entirely of building supplies.说明此5个orderedshipments运的都是building supplies
其次，从Four shipments were sent to Truax Construction last week, none of which consisted of building supplies.来看，因为此four shipments not consisted of building supplies，所以不可能是上周发出的5个special ordered shipments之一，也就不可能是special ordered shipments。
