diamonds

[ketkoag]

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

please tell me what is the difference between "discriminate from" and "discriminate between"

[poonam1279]

I think A is correct here (A) genuine diamonds from imitation diamonds

distinguish can be used either "distinguish x from y" (for similar thing like panting to painting) or "distingusih between x and y" (for completly different thing)
Same rule i think applies for discriminate. Any other ideas welcome

although never seem this idiom....but this idiom is quite similar to distinguish between X and Y....which is GMAT idiom....

so best looks to be C...

distinguish X from Y IMO is wrong in GMAT.

IMO C
discrimintae "between" X and Y seems to be a better idiom
