**donovan**, Monday, January 31, 2011 at 12:36pmI meant to add my thoughts: I think it is incorrect because of an inverse problem. To make it correct I would write it as:

All NBA basketball players are over 5ft tall

Russell is an NBA player

Therefore, Russell is over 6ft tall.

The second conclusion is correct.
