Predicting: Choosing a Sample - S1.E11

The city council wants to pass a bill that would prohibit commercial use of the marina. That would sacrifice Cynthia's sailing instructions. But just who is in favor of restricting use of the marina, and why? It takes a while for Cynthia and her friends to determine who to ask. As a result of that sample, Cynthia and her friends discover that the real impetus for the bill was that marina members were sick of an old sea dog's clunky boat. But he wants to show a council member that his boat is getting cleaned up.
