1. Divisible
When a number can be divided evenly by another number - it is said to be divisible by that number. So 6 is divisble by 3 - but is not divisible by 4. The GMAT - however is more likely to ask you whether 728 is divisible by 4. ( Yes it is)
Willl focus more on describing the pattern of reasoning than in paraphasing the content of the argument - questions of this type may read: Which of the following indicates a flaw in the reasoning above? - Susan's attempt to counter Tim's claim is bes
