正确答案：
E:At least one of the shipments sent to Truax Construction last week was sent out before Friday.
上周四运出去了五批特别订购的货
上周五运出去的所有货都是建筑材料
运输部门上个周末休息
上周运去建造局的4批货中，只有3批是建筑材料
由原文可见，最后一句话中，
既然周五送出的全部都有建筑材料，而Truax收到的那4批货中，只有3批是建筑材料，有一批不是建筑材料，结合周五送的都是建筑材料得知4批中的剩余那一批一定不是周五送出的。
再结合周末不送货这个条件，则可以得到这一单一定是周五以前送的
因此E是肯定正确的
