Task: Question Generation
Input (English): Passage: 1951 - Having already killed OCD patient Billy Brown at the Redding House Asylum, a psychiatrist experiments on simple-minded inmate Melvin Veman and sociopath Levius Laitura. With Levius still alive, the psychiatrist has his orderlies put the bodies of all three men inside the crematorium to burn them. 
Present Day - Camden College student Dylan tells his girlfriend Gabby and his roommate Kolt about the now abandoned asylum's haunted history. New student Emma moves in as Gabby's roommate and Kolt takes a liking to her. However, fellow students Allyson, Christine and Blythe do not.
Dylan, Kolt, Gabby and Emma break into Redding House after a party to look around despite a warning from campus security guard Clyde. Emma has strange experiences while exploring on her own. The other three knock over a container of cremated ashes and inhale the dust of the three men burned there in 1951.
A recovering psychiatric patient herself, Emma begins experiencing haunting visions upon returning to the dorm. The behavior of the other three students gradually changes as Billy possesses Dylan, Melvin inhabits Gabby and Levius takes control of Kolt's body.
Allyson is killed by someone unseen while doing laundry. Christine is later killed while taking her dog outside. Suspecting that the disappearances and the odd behaviors are related to the asylum, Emma tries to go back to Redding House, but Clyde prevents her from going inside.
With Levius in full control of his actions, Kolt attacks Emma. Emma eventually flees into the asylum and confirms her suspicions when she examines patient records and finds the empty urn knocked over by the others. Emma then finds the dead bodies of Allyson, Christine and Blythe (who was killed off screen).
Output (English): What three people knock over a container of cremated ashes and inhale the dust?
