Which term refers to the exchange of ideas among participants to explore a topic?

• A. Lecture
• B. Before Class Begins
• C. Discussion
• D. Safest

Answer: (C)

Discussion is the term for the exchange of ideas among participants to explore a topic. In a discussion, people share different viewpoints, ask questions, and respond to each other, which helps deepen understanding through collaborative inquiry. This kind of interactive dialogue contrasts with a lecture, which is typically one-way information delivery from instructor to learners. The other options don’t describe a process of exploring ideas together—timing that something happens before class, or an unrelated term—so discussion is the best fit.
