Question 7 is based on the news report you have just heard.

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. 

7. What do we know about the owner of the boat?

解析：B。本题目为细节题。问题为：我们可以了解到关于船主的什么信息？根据原文“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.”，国家新闻机构报道称，船主Blandon被尼加拉瓜当局逮捕，警方则称，Blandon及他的一名船员因非故意杀人和造成他人面临危险在接受调查。故正确答案为B）He is being investigated by the police（他正在被警察调查）。
