Assignment:
The requirements for the persuasive speech are the same as the informative speech except the intention of your speech is persuasive. This means in your introduction your specific purpose must persuade. For example, "Today I want to persuade (convince, or stimulate) you about being compassionate." Your thesis should break down "being compassionate" to two or three good reasons. And yes, your good reasons may sound like main points in your informative speech.
