Final answer:
The breadwinner-homemaker model of marriage is a traditional family structure where the husband is the primary breadwinner and the wife is the homemaker.
Step-by-step explanation:
The breadwinner-homemaker model of marriage refers to a traditional family structure where the husband is the primary breadwinner, responsible for earning income, while the wife is the homemaker, responsible for taking care of the household and children.
This model was more prevalent in the past when gender roles were more rigidly defined, and women were expected to prioritize their domestic duties over pursuing a career outside the home.
However, societal changes, such as the increasing number of women in the workforce and the shift towards more egalitarian gender roles, have led to a decline in the prevalence of this model in modern times.
