Three chests stand in a room: Gold, Silver, and Bronze. One contains a diamond; the other two are empty. Inscriptions read: Gold: 'The diamond is in this chest.' Silver: 'The diamond is not in this chest.' Bronze: 'The diamond is not in the Gold chest.' If exactly one inscription is true and two are false, which chest contains the diamond?
The Silver chest
If the diamond is in Silver, the Gold statement ('in Gold') is false, the Silver statement ('not in Silver') is false, and the Bronze statement ('not in Gold') is true. This results in exactly one true statement and two false ones.
