so basically I want you to write me some notes that will help in my graded class discussion. The class discussion is about Family roles and how they changed and different types of families such as traditional or nuclear family, single-parent family, etc. I want you to write about how their roles evolved through comparing to the 1950s maybe and now. also, how feminism was implemented into these families and their roles evolved. Also the change of the 20/21st-century families and what did influence the change of family roles.  I need at least 8 academic resources and cite them intext.
