考题讲解

情景：上周，没有建筑用品的货物是在周五被发货的。周四有五个特殊定制的货物被发出，每一个都全部由建筑用品组成。四个货物上周被寄送给了Truax，没有一个是建筑用品。

推理：本题由于没有结论，属于必然性推理。

选题方式：略。

选项分析：

A选项：所有上周的Comcrop的建筑用品货物都是特殊定制的。文段中说周四有五个特殊定制的货物被发出，并没有说所有上周的货物都是特殊定制的。

B选项：没有任何一个Comcrop在周五的货物是给Truax的。周五Comcorp没有发过关于建筑用品的货物，Truax也没有收到关于建筑用品的货物，所以我们无从确定Truax是否收到了周五发出的东西。

C选项： Correct. 没有一个Truax收到的来自Comcorp的货物是特殊定制的。五个特殊定制的货物都是在周四发出的，且都是建筑用品。但是，Truax没有收到任何建筑用品，所以，这些特殊定制的货物都不是发给Truax的。

D选项：没有一个在周四发出的Comcrop的货物是发往Truax的。文中只说了五个特殊定制的货物是周四发出的，且它们都是建筑用品，并没有说过所有周四发出的货物都是关于建筑用品的，所以我们不能确定周四是否有发给Truax的货物。

E选项：所有Comcrop的建筑用品货物都是周四发出的。文中只说周四发出了建筑用品货物，没有提及是否所有的建筑用品货物都是周四发出的。
