Task: Question Generation
Input (English): On December 8, 1980, Mark David Chapman shocked the world by murdering 40-year-old musician and activist, John Lennon, outside The Dakota, his New York apartment building. Chapman's motives were fabricated from pure delusion, fueled by an obsession with the fictional character Holden Caulfield and his similar misadventures in J.D. Salinger's The Catcher in the Rye. In one instant, an anonymous, socially awkward and mentally unstable 25-year-old fan of The Beatles, who had fluctuated between idealizing Lennon and being overcome with a desire to kill him, altered the course of the history of music.A man whose painfully restless mind thrashes about uncontrollably between paranoia, sociopathic lying and delusion is summed up in such character revealing comments as "I'm too vulnerable for a world full of pain and lies" and "Everyone is cracked and broken. You have to find something to fix you. To give you what you need. To make you whole again."From his lies to cab drivers (identifying himself as The Beatles' sound engineer) to his socially unacceptable behavior around Jude, a young fan he meets outside The Dakota, to his argument with paparazzi photographer Paul, Chapman keeps the psychoses bubbling below the surface as his grasp on reality deteriorates into a completely misguided rage.
Output (English): Question: Who did Mark assassinate?, Answer: Mark David Chapman
