Which term describes an open and informal gathering of people with a common interest that is not formally organized?

• A. Mass meeting
• B. Meeting
• C. Conference
• D. Assembly

Answer: (A)

An open and informal gathering of people with a common interest that isn’t formally organized is described as a mass meeting. This term captures the idea of broad participation and lack of formal structure—anyone can join, and there isn’t a formal organization directing the event. That openness and absence of a standing, organized body distinguish it from other types of gatherings. A general meeting can be any gathering for business and may be formal or informal, but it doesn’t inherently indicate broad public participation or a lack of formal organization. A conference is typically more formal, with a prepared program and delegates, while an assembly often implies a formal or legislative-type gathering. So the best-fit term for an open, informal, not formally organized gathering is mass meeting.
