The greatest changes have been in the lives of women. During the twentieth century there was a remarkable shortening of the time in a woman’s life spent caring for children. A woman marrying at the end of the nineteenth century would probably have been in her mid twenties, and would be likely to have seven or eight children, of whom four or five would live till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which time her state of health made it unusual for her to get paid work. Today women marry younger and have fewer children. Usually a woman’s youngest child will be fifteen when she is forty-five and she can expect to live another thirty years during which time she is likely to take paid work until her retirement at sixty. Even when she has to take care of her children, her work is lightened by modern living conditions.
This important cha
A. at about twenty five
B. in their early fifties
C. as soon as possible after they were fifteen
D. at any age from fifteen to forty-five
