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.

答案是哪个啊？ 怎么觉得哪个都不是啊？ specially ordered shipments 等不等于building supplies？ 不理解，望NN指教

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?

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

文章中并没有说，shipping department的shipments除了specially ordered shipments就是building supplies shipments,也有可能有其他种类的shipments。所以没法判定TC收到的除了building supplies以外的另一个是SPECIALLY ORDERED了。

2. At least one of last week’s specially ordered shipments did not consist of building supplies.

文中没有specially ordered shipments与building supplies shipments之间关系的描述，所以B错误

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

FLAW: 周四除了送出specially ordered shipments，还可能送出其他种类，其中包括building supplies shipments。所以也有可能送去TC的four shipments都是周四送出的。

4. At least one of the shipments that were sent out on Friday of last week was sent to Truax Construction.

同C，既然可以推得出送去TC的货可以全部在周四进行，同样文中没有提到的周一，周二，周三都符合。

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

周五的shipments只有building supplies，而送去TC的货只有三个是building supplies，说明一定有一个是在周五以外的时间送去的。正确

我 选 E。

考 虑 到 可 能 还 有 TRUAX以 外 的 客 户 的 货 物 运 输 ， 以 及 可

能 星 期 一 ， 二 ， 三 也 有 各 种 商 品 类 型 的 运 输 。

请 多 指 教 。
