The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
Women in hunter-gatherer communities had fewer children because it was difficult to take care of babies while living a nomadic life. On the other hand, women in agricultural communities could have more children because they lived in small villages. This change was one of the ways in which agriculture contributed to a rapid increase in the human population.
Before the advent of the Neolithic Age, humans were nomads. This means that they did not settle in one specific place. They had to follow the herds to hunt them and feed their families.
When humans started to develop agriculture techniques, they could settle in one place, as was the case of the Sumerians, the oldest civilization on planet Earth.
They settled in the middle of the Euphrates and Tigris Rivers, in modern-day Iraq, where they established powerful city-states such as Uruk, Lagash, Kish, or Nippur.
