Question

how can a teenager best avoid risky behaviors that lead to injury?
by refusing to drink alcohol
by speeding only when running late for school
by fighting only when provoked to do so
by attending parties where alcohol is present

Explanation:

Refusing to drink alcohol is a positive choice. Alcohol impairs judgment and can lead to engaging in other risky behaviors that might cause injury. Speeding (even when late for school) is dangerous and a traffic violation that can lead to accidents. Fighting (even when provoked) can result in physical harm. Attending parties where alcohol is present increases the likelihood of being exposed to and potentially consuming alcohol or being in an environment where other risky behaviors might occur.

Answer:

by refusing to drink alcohol
