What should be changed to make the following sentence true? Social exchange is people’s desire to help others even if the costs outweigh the benefits.

The phrase "social exchange" should be replaced by "altruism"

Explanation:

Altruism is selfless concern for the well-being of others. It is a moral principle that is concerned with helping others and making sure others are happy even at ones own cost.
