Three athletes: Ahmad, Bill, and Claire are preparing to take part in high jump competition. At the time some of the spectators are discussing their chances:
Spectator X: "I think Ahmad will be first"
Spectator Y: "I am sure that Claire will not be the last"
Spectator Z: "Bill will not take first place"

After the competition it turned out that only one of the spectators was right, while the other two were wrong. Where did Claire finish?

Suppose X is correct, and the other two are wrong. Then Ahmad was first, Claire was last, and Bill was first, which is a contradiction. 
Suppose Y is correct. Then Ahmad was not first, Claire was not last, and Bill was first, which is totally possible (B-C-A). Hence Claire finished second.
