Answer:
B. Allowed people to live in permanent settlements.
Step-by-step explanation:
Before the Neolithic Revolution, humans were hunter-gatherers, therefore they were nomadic and had to move around so that they could find food. Once people started settling in agricultural communities, they were able to grow their food and keep animals that could also be used for food/tools. They no longer needed to move around and they were able to settle in a permanent spot.
