What is a crowd showing sympathy for or against authority called?

A demonstration is an organized public display of group opinion, often about political or social issues, where individuals show their support for or opposition to authority or policies. Demonstrations can take various forms, including marches, protests, or rallies, and they aim to convey a specific message to the government, organizations, or the general public. The nature of a demonstration is typically peaceful, involving participants expressing their views in a structured manner, which is essential for democratic engagement and social change.

The other options do not accurately capture this social phenomenon. A riot usually involves violence and disorder, often exceeding the boundaries of a peaceful demonstration. A rave is primarily a large dance party featuring DJ performances and occasionally associated with electronic music culture, which does not inherently involve taking a stance for or against authority. The 'None of the above' option would imply that the term does not exist in this context, which is not the case, as 'demonstration' is widely recognized.
