Answer:
If Ria's school is moving from a traditional schedule to year-round schooling, and she is planning a presentation about the policy, her audience mostly consists of parents in the community. I think the kinds of questions this audience is most likely to ask are questions about the new schedule. They would probably want to know how the new schedule would affect their children's learning, social life, extracurricular activities, and vacations. They might also be curious about the reasons for the change and the benefits and challenges of year-round schooling.
