lol i like how we are all copying the answer of ms sue but thx becca for asking cause if you didn't i would fail science

would those be correct?

School council is a variation on school. Social systems that you're part of include your neighborhood, circle of friends, and perhaps your church/synagogue/mosque or Scouts, Y, etc.

Friends are not a naturally occurring social group because you choose your friends. In addition to family, people are born into an ethnic group and have kinship or tribal groups.

I dont know how did you get this question but this question is our assignment in science
