omidsa
I have searched OG12 for idiomatic phrases of distinguish and I found these : ‘
to distinguish x from y’ and ‘
distinguish between x and y’
Besides I found this in CR 52 :
q27-rye-sown-in-the-fall-and-plowed-into-the-soil-in-early-48860.html'distinguish among the various kinds of synthetic herbicides'
So the question is do we have "distinguish among" ? or Not?
GMAC the creators of GMAT have time and again hinted on the fact that there focus in SC is more on Meaning and Less on idioms. Having said that, its advisable to be well versed with the most common idioms but not to get carried away and start learning new ones with a huge list.
Distinguish between X and Y is the most common idiom used.
Distinction between X and Y is again the same thing.
As far as categorizing on the basis of numbers is concerned, here's a basic list:
