Final answer:
Edmund Leach identified several potential outcomes of marriage, including establishing legal parentage, granting sexual monopoly, conferring property rights, and creating relationships of affinity, though these are not always achieved.
Step-by-step explanation:
According to Edmund Leach, marriage can, but doesn't always, accomplish the following: a) establish legal parentage, b) give either or both spouses a monopoly on the sexuality of the other, c) give either or both spouses rights over the other's property, and d) establish a socially significant "relationship of affinity" between spouses and their relatives. However, the extent to which these are achieved can vary greatly depending on cultural norms, legal frameworks, and individual agreements within the marriage.
