The premise of education in the passage is that good models influence the young. From this, the author builds an argument to suggest what this premise implies—that bad models (like violence on TV) can negatively influence behaviour. Given this, the correct interpretation of what the premise proves in the context of the passage is that violence on television encourages violence in real life. This conclusion is drawn because if good models positively influence the young (the premise), then bad models, such as fantasized violence, likely have a harmful impact, including encouraging violence in real life.
