In Some Forager Societies, Patrilocal Residence and Cross-Cousin Marriage Combine

In some forager societies, patrilocal residence and cross-cousin marriage combine to create a system called restricted marital exchange. In this system, two groups exchange women. The purpose of this is to:

A) make sure that everyone in the group has a wife or husband
B) limit marriages to close friends and family members
C) foster group solidarity by encouraging kinship alliances
D) make sure that women do what the men want them to do
E) limit population growth and maintain the band well below the carrying capacity of the region
