60. 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

The key is c A为什么不对?不是也有discriminate A from B的结构吗? Thanks!

discriminate A from B 表示把A从B中区别出来,A可能包含在B里面

between A and B表示将A和B区分开,A 与B是不同的群体

不知对否

在字典里有:

discriminate between 区别; 辨别 discriminate...from... 分清...与...的差

是不是between和from是不同level的辨别?后者更难呢?
