Explanation:

Sociology can be defined as a social science that deals with the study of the socio-cultural interaction of humans with respect to the structure, functioning and development of their society.

The main purpose of sociology is to develop and enhance human knowledge or understanding of important socio-cultural processes through the gathering and analysis of all aspects of the social life of the people living in a society.

A sociologist refers to an individual (scientist) that studies sociology i.e a social scientist.

Sociologists study categories of people and the societal problems that affect them.

This ultimately implies that, sociologists study how society affects a group of people and how the people affect the society in return.

For example, how to treat employees nicely, what candidate to vote for in a presidential election, what career path to choose in life, when to marry, who to marry are all questions (challenges) that sociology help humans to understand.
