这道题实在看得我晕啊，想在知道大家的思路如何，请指教，谢谢！

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?

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

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

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

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

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

E. I think you can draw circles, if you cannot picture the question clearly enough in your mind.

请问D为什么不对呢?

From the conditions given in the passage:
- Shipments to Truax: 3 building supplies, 1 others
- Firday: all shipments are building supplies
We can't darw conclusion (D) At least one of the shipments that were sent out on Friday of last week was sent to Truax Construction
Because it's possible that all shipments to Truax were sent in days other than Friday.

A. 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.

B.Four shipments were sent to Truax Construction last week, only three of which consisted of building supplies.

这是唯一俩个明确的范围(premise):

A. 礼拜五的shipment都是building supplies

B. TC公司的四件shipment, 三件是 building supplis, 一件是other

由A.B仅可以推出那件other一定不是礼拜五.....

至于另一个premise:

C. The five specially ordered shipments sent out last week were sent out on Thursday.

这与B结合有太多可能性.....

以下是引用mindfree在2004-6-24 22:53:00的发言：

先谢谢以上各位指点哦，我又想了想总算想通了。

平时其它题都做得爽，就怕碰到这种题，几个条件给出来，绕啊绕的，脑袋都打结了。

这种思维比较绕的不知用什么方法最好，想问问总教头怎样“draw circle”啊？

同意选E.

选E，必要条件

5辆ship是specially ordered（礼拜四），礼拜五的ship只有building supplies

有4ship到了Truax Construction，其中3ship包含building supplies

E说至少有1ship在礼拜五之前出发，（假设没有ship出发于礼拜五之前，就是说所有的ship出发于礼拜五，那么4ship到达Truax Construction，都应该有building supplies）

why not to choose the A ? i think the A deliver the same meaning as E . because it is obvious that one of the shipments sent out to theTruax Construction is comes from the specially ordered shipments .

please N N give me a explication !

我也觉得是A阿。all of the shipments that were sent out on Friday consisted entirely of building supplies，这句话到底是说周五发出去的都是building supplies，还是，本周所有的building supplies都是周五发的。如果是后者，那答案就是A了
