【正确答案】This chart shows the weekly hours of unpaid labor for married men and women with and without children.
Married women with no children work almost twice as many unpaid hours at home than do their husbands do. According to the chart, this disproportion only increases with the number of children a married couple has. Married women with one to two children work almost three times more unpaid hours per week than their husbands do, while married women with three or more children work five times more unpaid hours of work per week than their husbands do.
As seen here and in most societies, women contribute tremendously towards the running of their households, all in the absence of monetary benefit.
