Re: GMAT question - symantic problem?

I can see one logical difference (maybe this is what you're getting at) - it's easier to evaluate the claim of the first statement because the relations are transitive, while the relations in the second statement are intransitive. That is, if a=b and b=c, then a=c. But if a!=b and b!=c, that doesn't mean that a!=c.

yes this is exactly what i was trying to get at
i don't follow the difference between groups of 3 and 5 or what you were trying to say with that. probably beside the point anyway.
