Marcus is discussing his violent reactions while driving.

Marcus says, "I don't know why I do it. Whenever another driver cuts me off or doesn't use their indicator, I assume they are doing it on purpose to provoke me. My heart starts pounding and I just want to scream at them or ram their car. I need to find a way to stay calm and stop reacting so aggressively."

Explain how an anger management therapist could help Marcus.
