Arousal can be defined as an imbalance between demand and response capabilities.

That statement is false

Explanation:

imbalance between demand and response capabilities is called stress, not arousal. (for example, a person can experience a stress if there is an imbalance between the time that he/she spend to work with the time that that person use to relax and have fun)

Arousal is different from this definition because  occurs when we have some sort of excitement because of the things that we do or the situation that we face.

no one should discriminated against because he or she is not from a minority group
