Victor wants advice about giving an informal talk. "Is it better to focus on a
broad topic or a narrow one?" he asks. What is the best advice to give Victor?
OA. "Make sure your topic is broad so you won't run out of things to
say."
OB. "Keep your topic narrow. You are speaking for only a few minutes."
OC. "Ask your teacher whether it makes more sense to have a broad or
narrow topic."
OD. "Start with a narrow topic, and then add to it until it becomes
broad."
