Answer:
The correct answer is: "C. By stating what the group will discuss first".
Explanation:
A good moderator is always someone who is responsible for organizing ideas and situations, he/she should always state the ideas to be discussed very clearly in the first place. This why letter C is the best answer. Letter A is not the best because it is not about setting clear goals, although it is important to ask for the group's opinions. Letter B is also not about setting clear goals, it only provides the moderator's position. And, letter D is not possible because to "summarize what was said" means that the discussion has already happened and this is the contrary situation for setting goals for a future discussion.
