Task: Question Generation
Input (English): In a very strange experiment by Andy Warhol, Empire is literally one continuous shot of New York's Empire State Building for eight hours and five minutes. Watching the same shot (which Warhol filmed on July 25 and 26, 1964 from the 42nd floor of the Time Life Building) the film is a test for the audience who sees how long they can sit and watch the same image for a long period of time. The only rewards for patience come from the occasional flicker of the lights on the building or Warhol's reflection in the glass as he changes the reel on the camera.
Output (English): Question: What was the only reward for patience?, Answer: <No Answer>
