Step-by-step explanation:
False. Polyandry is a very rare form of family structure existing in only a few societies. It is a type of marriage where one woman is married to more than one man at the same time. While polygyny, the marriage of one man to more than one woman, is more common worldwide, polyandry occurs in about 1 percent of the world's cultures. It is practiced in societies where there is a temporary surfeit of males or scarcity of resources, and it offers benefits such as collective subsistence and shared inheritance of land.
