Which definition best describes a "symposium"?

The definition that best describes a "symposium" is a presentation from an expert with various viewpoints presented. A symposium is typically a formal gathering in which experts in a particular field share their insights, research findings, or theories on a specific topic. It generally includes multiple speakers who may discuss different perspectives or aspects of the subject matter, allowing for a rich exchange of ideas. This format encourages scholarly dialogue and can lead to further discussion among attendees.

In contrast, while interactive workshops and study groups might involve active participation and focused learning, they do not capture the essence of a symposium, which is centered around expert presentations. Similarly, a casual gathering of professionals lacks the structured focus and depth of discussion that characterizes a symposium. Thus, the correct definition emphasizes the formal presentation of viewpoints by experts, aligning perfectly with the nature of a symposium.
