【正确答案】 C

【答案解析】[听力原文] Five children are among 11 people who drowned after a migrant boat sank near a Greek island on Wednesday. The Greek coast guard said a wooden boat with about 50 people on board sank after it left Turkey early in the morning. Thirteen people are still missing, but 26 were rescued. The deaths are just the latest in what has turned out to be a dangerous passage between Turkey and the Greek islands of the Aegean Sea this year. The International Organization for Migration (IOM) says more than 900,000 migrants made sea crossings into Europe this year from countries in the Middle East and Africa. Thousands more are trying to make the trip. The IOM reports almost 5,000 migrants were rescued in the first part of December by the Italian coast guard and Navy. The organization says over 21,000 migrants arrived in Greece by sea this month. In total, 3,600 migrants died making journeys from their home countries to Europe this year. On Tuesday, the Associated Press news agency reported six children died after a rubber boat sank shortly after leaving Turkey. How many people are still missing after the sinking of the boat? 新闻开头提到了一连串数字，其中说到13人至今下落不明(Thirteen people are still missing)，故选项C正确。四个选项中的数字在文中都有涉及，考生在听音时一定要注意每个数字所对应的对象，避免出现张冠李戴。
