Explanation:

- Your family: Families are the classic example of a primary group. They are small, characterized by close, personal, and lasting relationships.

- The school you are attending right now: Schools can foster connections, but they are more like secondary groups since relationships are more goal-oriented and less personal.

- The military: Similar to schools, the military is a secondary group. It focuses on tasks and achievements with formal, structured relationships.

- A large church: While it may offer community, its large size makes it more of a secondary group. Relationships tend to be formal and less personal.
