Answer: A hero award would benefit the school by encouraging students to stand up to bullies.
Step-by-step explanation:
An effective claim for the presentation which is to convince the school board to create an award for students who act heroically by standing up to bullies will be that "A hero award would benefit the school by encouraging students to stand up to bullies".
Bullying is the act of intimidating or frightening someone that one considers to be less powerful than himself or herself. When a hero award is given to a particular student, this will tend to motivate other students to stand up for bullied students whenever they witness students being bullied.
