Model United Nations (MUN)-
Students choose a country, research topics (provide by the conference) from the vantage point of the nation being represented, during committee sessions at the conference; debate between the nations is held on the topics, the countries then collaborate and write resolutions attempting to solve the issue at hand.
One of the key phrases used during preparation and during at conferences is "stay in character", representing other nations than your own, sometimes requires advocating viewpoints other than your own.
Preparation is the key to staying in character.
