Jeff's dog barks and growls at the sound of a stranger's car pulling into his driveway, yet the dog wags its tail and gets excited at the sound of Jeff's car. In this scenario, the difference in the dog's reactions to the sound of Jeff's car and that of a stranger's car is due to discrimination.
Explanation:
Discrimination is the practice of separating an undesirable being from the class, or category to which it is considered to correspond. Discrimination can be justified or it can be detrimental. Here the Jeff's dog barks for the stranger car because he is not aware about the stranger's sense thus he defend it, but when the dog saw Jeff's car he got excited for it because he is aware about his owner and loyal to him.
