OA A

Can anyone explain how do statements A, B & C differ in meaning?
A consequence of sitting...
A consequence from sitting....
A consequence which resulted from sitting.....

which of the above is correct?

ceilidh.erickson wrote:This is actually a difference of idiom, not of meaning. "Consequence of" is the correct idiom; "consequence from" is incorrect. "A consequence which resulted" uses the incorrect relative pronoun "which." It should be "that." On the GMAT, "which" will always come after a comma when used in this context.

"Damaged" in D and E would be an illogical modifier: it doesn't make sense to say "the impairment is damaged," because impairment already means damaged.

Thanks Ceilidh,

I didn't know this was idiom related. I could narrow down to A,B & C because I knew "damaged" is wrong.
Just could not figure out the difference in meaning. But now I got that it is not meaning related but idiom related.
thanks
