Final answer:
According to the functionalist view, families regulate sexual activity and ensure the reproduction and socialization of children, contributing to societal stability.
Step-by-step explanation:
According to the functionalist perspective, the two main functions of the family are the regulation of sexual activity and providing for the reproduction and socialization of offspring. Functionalists such as Talcott Parsons and George Murdock argue that families perform essential roles for the society, providing a stable environment for members through the regulation of sexual relations, which supports marital cohesion and family stability. This regulation aims to ensure that sexual activity occurs within the confines of marriage, thus solidifying the bond between spouses and securing a legitimate basis for family reproduction and the socialization of children.
