I am working on a group speech. The history of the telephone. I am in charge of the introduction and the conclusion. In the intro. I need 5 things:an attention getter, a central idea, indicate my qualifications, give the audience a reason for listening, and to preview our 3 main body parts. In the conclusion I need to restate the central idea and review the 3 main body points.Our main statement is: Technology has improved communication in many ways, 1 of the most dynamic transformations has been with the telephone. Our 3 main points are the early years, the acceptance years and future possibilities. An attention getter is the most important.Thanks!
