Today in the united states it is not at all uncommon for a woman to have her first child at what age?
a. 20
c. 42
b. 30
d. 18 select the best answer from the choices provided a b c d

The correct answer is 30: this is the age when most women have already gained an education and started their careers, but when they can still biologically have children: at the age of 42 some women would have problems having children, but around the age of 30 many women feel secure enough but also under the pressure of time.
