01 In a presentation the speaker gives the conclusion first and then explains the main reasons in order. When is this structure effective?
Answer and explanation
Correct answer: A. When listeners need to know the main message at the beginning
Explanation: The governing concept is purposeful organisation in verbal presentation. A conclusion-first structure is effective when listeners need the central message immediately, because the later reasons can then be understood as support for that message. Option A is correct. Unrelated reasons weaken coherence, lack of preparation is not a communication principle, and entertainment alone does not determine the best structure.
