A collection of people with the same rank and interest is an example of what?

The correct answer is a group. A group is characterized by a collection of individuals who share common interests, characteristics, or statuses, and often have similar ranks within a particular social or organizational structure. This concept highlights that members of a group recognize their shared identity or purpose, which distinguishes them from others who do not share these similarities.

In the context of teams or organizations, the focus is usually on collaboration towards a specific goal or the structured nature of a business entity, respectively. Teams are typically defined by their collaborative functions, while organizations are broader constructs that encompass various groups, teams, and individuals working together under a defined structure. The term 'force' is less commonly used in this context and does not typically relate to the collection of people sharing the same rank or interest.

Thus, the definition of a group captures the essence of individuals coming together based on shared attributes without necessarily implying any formalized structure or specific goals that are inherent in teams and organizations.
