In South Sudan, a Nuer woman can marry a woman if her father has only daughters but no male heirs. This is done to maintain the patrilineage. The wife has sex with one or more men until she gets pregnant. The children born are then accepted as the offspring of both the female husband and the wife. What is important in this example is
 
  A. the fact that only same-sex marriages are recognized in patrilineal societies.
  B. social rather than biological paternity, again illustrating how kinship is socially constructed.
  C. how biology overrides culture regardless of human intentions.
  D. how often marriage is simply about property.
  E. that it illustrates how romantic love is both universal and complicated.
