Final answer:
When asked to speak on the spot, you're likely to use a topical organizational pattern, breaking down main ideas into subcategories. Depending on the content, chronological or cause-and-effect patterns may also be suitable.
Step-by-step explanation:
If you're asked to speak on the spot, you are likely to employ a topical organizational pattern. This pattern allows you to break down the main ideas into smaller ideas or subcategories. After dividing the topics into subtopics, you should consider the most logical order of points. While there may not always be an exactly right answer for this order, you should aim to arrange your ideas to have the greatest impact. For instance, when discussing historical events such as World War II battles, a chronological pattern might be most effective, as it follows the time sequence of events. Alternatively, a topic that investigates the causes of World War II can be broken down into diplomatic factors, nationalism, and the World War I peace treaty without fitting into a clear-cut pattern. In persuasive scripts, patterns like cause-and-effect may be best for organizing your ideas.
