Question

For the last five years, the Colby Street pie-eating contest has been won by a different person every year. Two years ago, the winner was Mr Green, and Mrs Black was runner-up.

Last year, four contestants entered: Mr Green, Mrs Black, Miss Orange, and Ms White.

Ms White had no appetite and finished last.

Mrs Black started well but didn’t do as well as she had the previous year.

Who was last year’s runner-up?
