Arrange the following steps in the development of agrarian societies in the correct sequence: A) Emergence of social hierarchies, B) Adoption of advanced farming techniques, C) Establishment of permanent settlements, D) Increase in food production.

To understand the development of agrarian societies, we need to look at the steps in the right order. First, people began to adopt advanced farming techniques, which allowed them to grow more food efficiently. As they produced more food, they could settle in one place, leading to the establishment of permanent settlements. With these settlements, some people became more powerful or wealthy than others, resulting in the emergence of social hierarchies. For example, in a village where farming improved, some families might have more land and resources, creating a social structure where they held more influence over the community.
