Task: Question Generation
Input (English): Passage: The opening scene sees "The Man" being approached and attacked by two muggers in a dark alley of London. As the muggers check their seemingly unconscious victim for cash, The Man regains consciousness and brutally kills them. Around that time, Inspector Peter Neilson is investigating the apparent murder scene of the young Melissa and Nikki. In a flashback, the two girls are shown in a goth club looking to pick up men. Melissa spotted The Man and took him home. After spending the night with him, she began hallucinating about the people around turning to her with monstrous faces and voices. Melissa went to Nikki's house to seek help, then a creature burst out of Melissa's womb and attacked Nikki, killing both.
Sophie and Emma break into a house in a burglary attempt. When Emma finds a box of money under a bed, a bony old man pops up from the bedcovers and attacks her. The girls stab and bludgeon the old man multiple times before he finally dies. Intending to keep the loot to herself and seeing Emma as a liability for revealing their plan to her sister, Sophie kills Emma and runs home. There, the re-animated bodies of Emma and the old man appear and stab Sophie to death.
As the dead bodies are identified, Inspector Neilson links them to an earlier case he had solved in the past. The case involved a man named Kemper, former hypnotist and son of an infamous Satanist. Kemper had been using his skills to manipulate, abduct and kill children for over 25 years until he was apprehended by Neilson, tried and committed to a lunatic asylum. Neilson's boss has Kemper transferred to another facility so that his cell can be investigated.
Output (English): What are the names of the people who stab an old men?
