This method is commonly used in various settings, such as educational environments, interviews, and online forums. It encourages interaction and helps clarify information on specific topics. In a Q&A session, participants can ask about anything from science to technology or personal experiences. The answers provided can come from experts, peers, or even automated systems. This format promotes knowledge sharing and can be an effective way to engage audiences in discussions.
