If the shipping clerk's statements are true, which of the following must also be true?
【选项】At least one of the shipments that were sent out on Friday of last week was sent to Truax Construction.
the original statement is: all of the shipments that were sent our on Friday consisted entirely of building supplies. This is not saying that all the shipments consisted of building supplies were sent out on Friday.
理由同C,我们并不能由题目推出那些个建筑材料是周五发出去的,题目并没有说周一,二,三,四中没有含有建筑材料的
也许之前也是有发出有载货物的船,所以无法判断一定是周五发出
反面:周五走的船没有一个去TC
上周四送的货都是特别订货。上周五送的所有货都是建材。周末不送货。上周有四艘送到TC的货,其中只有三艘是建材。 这个选项说上周五送出的货中至少有一艘是送到TC的。虽然原文说的是上周五是送的都是建材,而且送到TC的四艘里面有三艘是建材,但是不能推断他们是在周五送去的。因为周一到周三也有可能送建材啊,那么送到TC的建材就有可能是在周一到周三的哪天送过去的,就不是在周五送过去的。
Last week, all of the shipments that were sent out on Friday ,不确定这是周几发出的Four shipments were sent to Truax Construction last week, only three of which consisted of building supplies.
