Guys,

query 1

Does GMAT test usage of WHO and WHOM and WHOSE in SC ?

If so, how must we distinguish among them

i mean i know for a fact that WHOM is object pronoun / who subject and whose possessive pronoun !!

query 2

I have seen WHOSE taking non-living entities!!
Is that acceptable..??
example from OF

...Clans, whose access to water was less limited...


????
