标题: 大全sectionC-1 关于discriminate

1. After a few weeks’ experience, apprentice jewelers can usually begin to discriminate, though not with absolute certainty, genuine diamonds from imitation diamonds.

(A) genuine diamonds from imitation diamonds

为什么选C 不选A？

discriminate from 和 between 的用法不是都有么？

是不是因为介词和宾语之间不能插入其他成分（though not with absolute certainty），所以不能选A ？

A from B，B是大范围

between A and B, A和B是同等级概念

牛津高阶把这两个列在一起解释为see or make a difference between two things。

能不能from 的举个例子呢？谢谢*^.^*
