Task: Question Generation
Input (English): Passage: In a small New England town during the frigid winter season of 1979, four elderly friends—businessman Ricky Hawthorne, lawyer Sears James, Dr. John Jaffrey, and Mayor Edward Charles Wanderley—form the Chowder Society, an informal men's club who get together each week to share tales of horror. Edward's son David, living in New York City, falls from his apartment window after seeing a girl he's been sleeping with suddenly turn into a living corpse. His other son, Don, comes home at Edward's request. Some time after David's funeral, Edward sees him walking through town during a snowstorm and follows him to a bridge, where he disappears. Calling out to his dead son, he suddenly sees a female apparition and he falls to his death from the bridge. Meanwhile, two escaped patients from a mental asylum, Gregory and Fenny Bate, have taken up residence in the old Eva Galli house, now in ruins.
Output (English): Who disappears at the bridge?
