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.
关键是对这句话的理解：注意特指，那5个特殊箱子是在周四送出的。

并没有说周四只送了 5个 special order，如果周四还送了普通的 order，那么有可能还是有送去comcorp的order。

GWD-3-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.

A. At least one of the shipments sent to Truax Construction last week was specially ordered.

C. At least one of the shipments sent to Truax Construction was not sent out on Thursday of last week.

這題的關鍵在於是問must also be true
所以題目說
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.
可以確定的是 4 shipments were sent to TC last week≠5 specially ordered shipments =>(C)
但是(D)C上星期二送出去的貨物沒有一個是送到TC的-->則無法明確推知

The five specially ordered shipments sent out last week were sent out on Thursday,
主要是这句话的理解。这句话只是说五个特别预定含有BS的实在周四发出。并没有说周四发出的只有五个含有BS特别预定的货物。所以D那个选项无从推断

做XDF小蓝看到这道题,做对了选E,但是一直对C,D,耿耿于怀.想了十分钟,拿出来和大家分享一下.

GWD-3-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.
(至少有一个货物不是在Thur发出的->那么有可能是4个货物都不是Thur发出的而在Friday发出,可见C表述中可能存在的情况是错误的,所以C是错误的.也就是C蕴涵的各种情况中存在错误的.)
D. At least one of the shipments that were sent out on Friday of last week was sent to Truax Construction.(用类似的方法,至少有一个货物是Fri发出的->也就是可能四个货物都是Fri发出的,这也是错误的,不可能四个货物都是Fri发出.D蕴涵的各种情况中存在错误的.)
E. At least one of the shipments sent to Truax Construction last week was sent out before Friday.

总结一下整体思路：

1. 没有装 building supplies 的船周五发出（a）；specially ordered 的船周四发出，且都装 bs （b）；发往 TC的船都没装 bs （c）。

2. 选项A：所有装 bs 的船都是 specially ordered 的。
选项B：没有船周五发往 TC。
选项C：没有发往 TC 的船是 specially ordered 的。
选项D：周五没有船发往 TC。
选项E：所有装 bs 的船都是周五发出。

3. 选项A 对应题干 b，但 b 不能 -> A。
选项B 对应题干a + c。（a + c）= 有可能有没装bs的船周五发往TC 不能 -> B。
选项C 对应题干b + c。（b + c）= 没有周四发出的 specially ordered 的船发往 TC （取非，若有，则必定装有 bs，与题干 c 矛盾）-> C选项。
选项D 对应题干a + c。（a + c）不能 -> D。
选项E 对应题干a。E 与 a 矛盾，所以不正确。
