Determine whether the following dispute is verbal, factual, or some combination of the two. If verbal, discuss whether the dispute arises from vagueness or ambiguity.
ROGER: I think modern society is becoming more and more violent every day. Just look at the increase in murder, rape, and robbery. Violence is clearly an evil that must be eradicated.
MARK: You might be right about the increase in crime, but the idea that violence is an evil is nonsense. Violence is quite natural. The universe was created in a tremendously violent big bang, the nuclear reactions that bring us sunlight are extremely violent, and insects and animals kill and devour one another all the time.
