Final answer:
Marriages of men to MMZDDs might be encouraged for companionship, continuation of lineage, and economic advantages.
Step-by-step explanation:
In some societies, the marriage of a man to a MMZDD (a woman engaging in same-sex relations or cross-gender practices) might be encouraged for various reasons. One reason is to provide companionship and emotional support for lonely wives in polygynous marriages where they may spend many nights alone. Another reason is to continue the family lineage and ensure the inheritance of property through the practice of female husbands in certain cultures. Additionally, in some cases, polygynous marriages are seen as an economic enterprise that creates greater opportunities for all family members. These examples demonstrate how cultural, social, and economic factors can influence the encouragement of such marriages.
