Answer:
influence
Explanation:
The options for this question are:
a) influence
b) authority
c) political organization
In sociology, the term influence refers to the change of behavior that one person causes in another person (or group). This influence can be either intentional or unintentional. And this happens when the other people start thinking different based on the "influencer" opinion.
In this example, the headman of a tribe has declared that certain cuts of meat should be reserved for himself and his family, however, a member of the tribe points out that meat has always been shared equally among tribe members. This member has no authority (it just a regular member of the tribe), but this member has spoken out his mind and is trying to reach attention to the fact that according to tradition, food has always been shared (and thus, confronting the headman's authority), by doing this he intends to be an influence on the tribe so tradition continues the way it has always been.
