Question 5 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. 

5.  What happened to the tour boat sailing off the Nicaraguan coast?

解析： D。本题为细节题。问题为：船只驶离尼加拉瓜海岸时发生了什么？根据原文“A tour boat turned over off the coast of Nicaragua, killing at least 13 people and leaving more passengers missing, officials said.”，可知官方表示一艘游船在尼加拉瓜海岸附近发生了翻船事件，造成13人死亡，多名乘客失踪。故正确答案为D）It turned over because of strong winds（由于强风，发生翻船事件）。
