Answer:
B. Leslie had more dopamine receptors than other participants.
Explanation:
Ritalin (methylphenidate hydrochloride) is a central nervous system stimulant drug used to treat Attention Deficit Hyperactivity Disorder (ADHD). Ritalin also serves to treat narcolepsy, a sleep disorder that is characterized by excessive daytime sleepiness, even if the person has slept well at night.
Ritalin increases the activity of certain areas of the brain that are poorly active, promoting increased attention and concentration, and decreasing impulsive behavior. In narcolepsy, Ritalin works by relieving sleep throughout the day. The mechanism of action of Ritalin is the same as that of amphetamines and other stimulants, ie it increases the concentration and reuse of neurotransmitters such as dopamine and norepinephrine in the brain. For this reason, people with more dopamine receptors in their brain (such as Leslie) when taking ritalin feel pleasant feelings.

Speed is an important component of Tennis, Soccer and Swimming.
Explanation:
Tennis, Soccer and Swimming are the sports which require instant moves with high speed.
- Tennis requires immediate speedy moves to catch the ball. If the speed of the player doesn't vary with respect to the ball hits, there will be chances of losing the game. So speed is crucial in Tennis.
- Soccer is a game in which players run after a ball to do the goal. Here speed also plays an important role. If the speed of the player is not good enough, there are pretty chances that other players may take the ball and do the goal.
- Swimming is the game which is solely dependent upon speed. The swimmer who has the highest speed will win.
So speed is an important component of all of the above mentioned sports.
