Example Input: Question: How many books has the author of the children's book that inspired the character of Princess Fiona written? Passage:Created by screenwriters Ted Elliott and Terry Rossio, Fiona is loosely based on the unsightly princess in William Steig's children's book Shrek!, from which her role and appearance were significantly modified. The screenwriters adapted the character into a princess under a shapeshifting enchantment, an idea that was initially greatly contested by other filmmakers. Fiona is voiced by actress Cameron Diaz. Comedian and actress Janeane Garofalo was originally cast as the character until she was fired from the first film with little explanation, although it is believed that the producers found Garofalo's sarcastic approach to the princess unsuitable after Shrek's original voice actor died. Fiona was one of the first human characters to have a lead role in a computer-animated film, thus the animators aspired to make her both beautiful and realistic in appearance. However, an early test screening resulted in children reacting negatively towards the character's uncanny realism, prompting the animators to re-design Fiona into a more stylized, cartoonish heroine.

Example Output: Created by screenwriters Ted Elliott and Terry Rossio, Fiona is loosely based on the unsightly princess in William Steig's children's book Shrek!, from which her role and appearance were significantly modified

Example Input: Question: Which horse came in second in the King's Plate the year that Bunty Lawless was the top 3-year old in Canada? Passage:Racing during the Great Depression of the 1930s, Bunty Lawless competed for purse money that was very small. At age two, he finished first or second in all but one of his ten races. The one time he was out of the money that year was in the Cup and Saucer Stakes, when his equipment broke. In 1938, the horse was the top 3-year-old in Canada, and his victory in the King's Plate, his country's most prestigious race, was enormously popular with the public. In an era when millionaires still dominated Thoroughbred horse racing, the owner and breeder of Bunty Lawless was the opposite. The working man's hero, Willie Morrissey grew up penniless in the poorest section of Toronto, worked as a newsboy, then became a successful hotel owner and boxing promoter. At the race track, he sat in the cheap grandstand seats with the rest of the crowd and was frowned upon by the aristocratic elite owners in their top hats and tails, seated in their exclusive viewing boxes.

Example Output: In 1938, the horse was the top 3-year-old in Canada, and his victory in the King's Plate, his country's most prestigious race, was enormously popular with the public

Example Input: Question: Which film directed by Lean did better at the box office - the film released in 1949, or the film released in 1950? Passage:The next film directed by Lean was The Passionate Friends (1949), an atypical Lean film, but one which marked his first occasion to work with Claude Rains, who played the husband of a woman (Todd) torn between him and an old flame (Howard). The Passionate Friends was the first of three films to feature the actress Ann Todd, who became his third wife. Madeleine (1950), set in Victorian-era Glasgow is about an 1857 cause celebre with Todd's lead character accused of murdering a former lover. "Once more", writes film critic David Thomson "Lean settles on the pressing need for propriety, but not before the film has put its characters and the audience through a wringer of contradictory feelings." The last of the films with Todd, The Sound Barrier (1952), has a screenplay by the playwright Terence Rattigan and was the first of his three films for Sir Alexander Korda's London Films. Hobson's Choice (1954), with Charles Laughton in the lead, was based on the play by Harold Brighouse.

Example Output:
