Task: Question Generation
Input (English): A South Seas island prince is wrongly convicted of murder and executed by having a knife driven into his heart, the result of a plot by a witch doctor (the true murderer) who resented the prince's friendly relations with American scientists stationed on a field laboratory on the island. The prince is buried in a hollow tree trunk and forgotten about until nuclear radiation reanimates him in the form of the "Tabanga", a scowling tree stump. The monster escapes from the laboratory and kills several people, including the witch doctor, whom the Tabanga pushes down a hill to be impaled on his own crown of shark teeth. The creature cannot be stopped, burned, or trapped. Only when a crack rifle shot from one of the scientists drives the knife (which still protrudes from the creature's chest) all the way through its heart does it finally die and sink into the swamp.
Output (English): What reanimated the Prince?
