Answer:
Peer Pressure
Step-by-step explanation:
Peer pressure is the effect of peers, members of social groups with common interests, experiences, or social statuses, on one other directly or indirectly. A person's opinions and conduct are more likely to be influenced by peers.
Zack's group of musical friends has led him to not only move away from his old friends, but also to become more interested in music than sports. Peer pressure occurs when your opinions or ideas are swayed by peers or friends who may have similar interests.
