下面这题答案是C。应该是在考discriminate的搭配问题，但是查过牛津字典，discriminate可以是discriminate A from B 也可以是discriminate between A and B. 为什么不能选A呢？谢谢

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
(B) genuine diamonds apart from imitations
(C) between genuine diamonds and imitation diamonds
(D) among genuine diamonds and imitation diamonds
(E) whether diamonds are imitation or genuine

好像是说如果A属于B，用from,如果A\B独立，就用between
这里是真的宝石和假的宝石区分开来吧，所以用between
如果是把真的宝石从一堆宝石里区分出来，就得用from了

很有道理，谢谢。

这道题还有一个解释，说是插入语的问题，中间那个though not with absolute certainty插入语的位置不好, 通常插入语不应该在动词和名词之间，用带介词的between…and…比较好, 避免了这种问题
