Answer:
4. Increased aggressiveness while driving.
Explanation:
When a person is on cocaine, it affects immediately blood-brain barrier and it impacts serotonin, which regulates alertness and arousal. In this state, the person will be energized, they will feel euphoric, they will get a tremendous self-esteem etc.
People that are driving under influence, especially cocaine, are most likely to over-speed because risk appetite is significantly increased. So they will want to drive fast so they can match their happiness and state of euphoria.
When it comes to males, they will want to feel ''macho'' and a sense of aggression will incline them towards road rage.
People that DUI usually have a feeling like vehicles move way slower than them. They will want to cut in other drivers which is followed by loss of control of the car, which results in car crashes and they are, unfortunately, frequently followed by death.
Mason should (B) increase the speed at which he runs, because he is at practice and is simply told for how long he can run, but not at which pace. He wouldn't make a great impression on his coach if he ran for too long and missed out on important exercises. Thus, it would be better for him to just speed up as that increases his heart rate. Additionally, if he were to decrease either the time or the speed at which he runs he would only lower his heart rate.
