You are assigned to be the moderator of a group discussion about a short story you’ve read. After about ten minutes, the participants begin going off topic and interrupting each other. What is the best solution for getting the group back on track?

Speak loudly to command attention, announcing that people must follow directions.
Listen closely, smile, and add your opinion when you find a good time to talk.
Let the speaker finish, review the ground rules, and ask the group a new question.
Open to a good page of the short story, read it to yourself, and wait for a quiet moment.
