E  

周五的shipments全部是building supplies ;  Truax 共有四个shipments, 其中三个是building supplies, 一个是非builiding supplies.   极端情况，假设三个building supplies shipments 都在周五发出，那也至少有一个是在周五以前发出。

The five specially ordered shipments sent out last week were sent out on Thursday 属于烟雾弹

那请问A项和E项不是一个意思么？

E is correct.

(A) could be wrong because we do not know what was shipped out on Monday, Tuesday, and Wednesday.  Maybe a non-special ordered, no-building material reached the T-company.
