Who makes the announcement?The ______ of the city. [originaltext]As your mayor,

As your mayor, I am pleased to announce a free concert at City Hall next Friday. The concert will start at 8 p. m.. The musicians are all local teenagers. They have worked very hard all year to make this performance a celebration and a success. There are only 500 seats in the hall. So be sure to get your tickets early. You can get tickets at Room 405, City Hall. Support these 100 hardworking young people by making a good attendance next Friday.
