How many people are on your side? How do you want to split the program?
The first person does an introduction which is a high level review of your goals for the debate. "Using.....facts, figures, interviews, news articles, crime statistics, etc, we plan on proving that country life is not better than city life...."
Depending on how many people in the team.....each participant would fill out the details and take a topic: crime, entertainment, community, transportation, medical facilities, highway access, etc.
Finally, the last person speaking will wrap it up by summarizing the most interesting and compelling arguments that favor your side.
