Final answer:
There are three scenarios that contribute to the slowing of population growth: a new vaccine that reduces infant mortality, college campuses offering free contraception, and higher education levels among women.
Step-by-step explanation:
Three scenarios that contribute to the slowing of population growth include:
- A new vaccine that protects children from a deadly virus reduces infant mortality rates, leading to lower birth rates.
- College campuses offering free contraception provide individuals with access to birth control, which can help in planning pregnancies and reducing the number of unintended pregnancies.
- A town where 75% of women have a college degree indicates a higher level of education, which often correlates with smaller family sizes and delayed childbearing.
