A primary group consists of close, enduring relationships, while a secondary group is larger and more task-focused. In-groups are those towards which loyalty is felt, while out-groups evoke feelings of antagonism and contempt.

Explanation:

A primary group is a small social group where members share close, personal, enduring relationships, marked by concern for one another, shared activities, and culture. Families and close friends are examples of primary groups. In contrast, a secondary group is larger and more impersonal, formed from sharing a common interest, and is task-oriented rather than emotional.

An in-group is a group toward which one feels particular loyalty and respect, while an out-group is a group toward which one feels antagonism and contempt.
