On average, European women are 10 years older than women in sub-Saharan Africa when they have their first baby. Which of the following is not a contributing factor to this?

Choice C is not a contributing factor because greater knowledge of family planning and access to contraceptives would generally help women delay pregnancy, not explain why first births occur earlier. The other choices describe factors that can contribute to later first births in Europe, such as more time spent in education and a stronger focus on careers.
