Example Input: Question: Who was the ruler of Prague the year young Alfred was sent there? Passage:Piccaver was born on 5 February 1884 in the Lincolnshire town of Long Sutton to chemist Frederick Herman Piccaver (born 1864, died 17 February 1916) and his wife Sarah Ann Sissons. The Piccavers had been farm laborers, but there were also claims of Spanish ancestry dating back to the Spanish Armada. At a young age, Alfred emigrated with his family to the United States of America. The family resettled in Albany, NY and took American citizenship. Frederick Piccaver worked as head brewer of the Beverwyck Brewery. Alfred joined the choir of Albany's St. Peter's Episcopal Church as a boy soprano. He also became a soloist at the North Reformed Church in Watervliet. The young Piccaver went on to study voice with S. Graham Nobbes, who had been chief instructor of the Emma Willard Conservatory of Music and with Allan Lindsay, conductor of the Troy Conservatory of Music. Alfred later trained to be electrical engineer but he had a talent for singing and in 1905 he enrolled at the Metropolitan School of Opera. The school's director Heinrich Conried recognised his considerable vocal ability and in 1907 sent the young Alfred to Prague, where he studied with Ludmilla Prochazka-Neumann (1872–1954).

Example Input: Question: How many years after Thorgerson designed the cover with the man on fire for Pink Floyd did he pass away? Passage:Storm Thorgerson, who had done the majority of album covers for Pink Floyd, did the Echoes art which features recursive windows in an infinite regression as a nod to his own cover for 1969's Ummagumma, and the objects on each landscape refer to the Pink Floyd discography. For instance, there's the man on fire from Wish You Were Here, another wearing the Delicate Sound of Thunder lightbulb suit, dolls of the Atom Heart Mother cow and the Animals pig, a bike and both a brick wall and the hammers from The Wall. Eventually Thorgerson opted to make two images, with another used for the back cover. To create the idea on a photograph, various walls - which had varied measurements and angles to ensure that "nothing seemed to fit other than by eye through the lens." - were built and put in a country landscape in Sussex. Actors, props and fittings were set in and between those walls. The original design was one of two sketches submitted for Dream Theater's 1997 album Falling into Infinity, with the original being framed and hanging in the home of former Dream Theater drummer Mike Portnoy and is pointed out by Portnoy in his Hudson Music instructional drum DVD In Constant Motion.

Example Input: Question: Which play ran longer, the one where Ms. Kendal played Mrs. Fitzroy, or the one where she played Lady Hilda? Passage:The Kendals joined the actor John Hare at the Court Theatre in March 1875, opening in a new comedy, Lady Flora. Hare had a comic character role, and the Kendals played the romantic leads, Flora and Harry Armytage. She went on to play Mrs Fitzroy in Hamilton Aide's A Nine Days' Wonder, and then Lady Hilda in Gilbert's fairy comedy, Broken Hearts. She played Susan Hartley (a part she reprised in several later revivals) in Palgrave Simpson's adaptation of a French comedy, called A Scrap of Paper. In September 1876 the Kendals moved to the Prince of Wales's Theatre under the management of the Bancrofts. There Madge played Lady Ormond in Peril, a carefully anglicised French comedy. She subsequently played Clara Douglas in Money, Lady Gay Spanker in London Assurance and Dora in Sardou's Diplomacy, the last of which played for twelve months, in London and on tour. The Kendals returned to the Court, where they revived A Scrap of Paper in January 1879. In February, in her brother T. W. Robertson's adaptation from the French, The Ladies' Battle, the Kendals played the Countess d'Autreval and her suitor, Gustave; in April she played Kate Greville in The Queen's Shilling, an adaptation of an old French comedy by Jean-François Bayard.
