听力原文：

    （5）A tour boat turned over off the coast of Nicaragua, killing at least 13 people and leaving more passengers missing, officials said.

    （6）The boat was carrying 32 people—25 Costa Ricans, four Americans and three Nicaraguans. The 13 dead were all Costa Rican, the Foreign Ministry said. The boat, traveling between Nicaragua’s Big Corn Island and Little Corn Island, turned over Saturday near the larger island. Some passengers remain missing, the Costa Rican Foreign Ministry said, but did not specify how many. A local radio said an unspecified number of people were rescued, including the tour boat’s owner, Hilario Blandon.

    （5）Nicaraguan naval authorities had banned sea travel in the area because of bad weather and strong winds, but the tour boat proceeded anyway. （7）Blandon, the boat’s owner, has been arrested by Nicaraguan authorities, the state-run news agency said. Both he and a crew member are being investigated for unintentional murder and exposing people to danger, according to police. 

6. How many people was the boat carrying?
