A、Five. B、Four. C、Three. A每年的复活节期间，英国都会举行牛桥(牛津大学和剑桥大学)划船比赛。目前这一大学赛事已呈国际化趋势，文中信息告知在两条龙舟上只有5位英国学生，其余选手均来自其他国家。

The University Boat Race is a uniquely British institution but it’s taken on a distinctly international character. It dates back to 1829 and is now broadcast on television in more than a hundred countries. And of the sixteen rowers in the two boats, only five were British this year. It was the first time a French rower had taken part for at least a century. There were also four Americans, three Germans, two Canadians and an Australian.
Question: How many British students joined the University Boat Race?
