As in

2) Idiom

Assistance for ... ?
Assistance of?

3) Is there a plural for population ? I mean populations .. is it correct ? We found a sentence where populations was correct .. Not sure if it is correct
Q 10 , V 4.4 QLT 2

4) When to use WHO and WHOM

eg IT is he who/whom I want to talk with.



5) Give a sentence where the usage is correct for the idioms :
IDIOM : go out / go with

Population is a collective noun and hence it has to be singular.
Never Heard of anything like populations :shock: :shock:

When to use WHO and WHOM
Who==> Subjective Case

Whom ==> Objective case

IT is he who/whom I want to talk with.
ans: whom

There is a detailed discussion on this, just one line won't suffice
distinguish between / among
Between when two things are compared
Among= more than 2 things
compared to /. with
compared to : Comparison of unlike things for similarity.
compared with : Comparison of like things for dissimilarity.



Hope this helps

Compare to compares UNLIKE things to stress resemblance.
Compare with compares LIKE things to show similarity or difference (mostly difference).

Eg:
He compared her to a summer day
The police officer compared the forged signature with the original.
