[高手请进]discriminate用法/885/section c/1

mzyzhu

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

W-M上只有discriminate among historical sources.那么为什么答案是C而不是~ A from B, 或者~ among As and Bs.

Just like OG “Distinguish between...and...”. 是在真钻石和假钻石之间分辨，而不是把真钻石从假钻石中挑出来。
among表示不同种物品之间的选择，例如钻石、玉石、玻璃之间。

有点意思。
