Dax has been working on his speech for several weeks. After carefully crafting his purpose and thesis, Dax did extensive research and organized his main points and subpoints. He has a strong introduction and conclusion and is very proud of his formal outline. A few days before his speech, Dax prepares informal speaking notes and begins to practice. Although he has put so much work into his speech, he doesn't want to appear stiff or formal. He wants to give which type of speech, so he can appear natural and relaxed?
