The correct answer is B) promote cooperation.
Based on Bonta’s (1997) research on nonviolent societies, a powerful way to reduce violence within a society would be to promote cooperation.
That is exactly right. The problem in today's society is that everything is based on competition. Society is getting used that there has to be only one winner and everybody is a looser. This has created an aggressive competitive society that does everything in order to win, no matter what; including the use of aggression, lies, violence, and cheating.
But the truth is that through cooperation, more can be accomplished by many. Winning or losing would be out of the question when we step us through help, cooperation, tolerance, and respect.
