Example Input: Question: What college did the center attend who Payton was traded for prior to the 2004-05 season? Passage:Prior to the 200405 season, the Lakers traded Payton and Rick Fox to the Boston Celtics for center Chris Mihm, small forward Jumaine Jones and point guard Chucky Atkins. While Payton expressed displeasure with the trade, he ultimately did report to Boston and began the 200405 season as the Celtics' starting point guard. On February 24, 2005 Payton was traded to the Atlanta Hawks in a deal that brought former Celtic Antoine Walker back to Boston. The Hawks then waived Payton immediately following the trade, and he returned a week later to Boston as a free agent. Payton started all 77 games he played for Boston and averaged 11.3 points per game and 6.1 assists as the Celtics won the Atlantic Division before losing in the first round to the Indiana Pacers.

Example Input: Question: How many players did the Dallas Stars have on the team when they played the Montreal Canadiens for the last time? Passage:On March 11, 1996, the Montreal Canadiens played their last game at the Montreal Forum, defeating the Dallas Stars 4-1. The game was televised on TSN and TQS in Canada, and on ESPN2 in the United States. The Stars' Guy Carbonneau, who had captained the Canadiens from 1989 to 1994 (including their 1993 Cup win), took the ceremonial opening faceoff. After the game, many previous hockey greats were presented to the crowd, most notably Maurice Richard (said to be the Canadiens' most beloved player of all time), who received a sixteen-minute standing ovation from the crowd as he broke down in tears. A symbolic torchrepresentative of a line quoted from the poem In Flanders Fields, "To you from failing hands we throw the torch; be yours to hold it high," displayed in the Forum's home dressing roomwas carried by Emile Bouchard out of the Canadiens dressing room to the playing surface. The flaming torch was passed on to each of the former Canadiens captains (Jean Beliveau, Yvan Cournoyer, Henri Richard, Serge Savard, Bob Gainey, and Carbonneau), and finally to the then-current captain Pierre Turgeon. The next day, a parade was organized in which the torch was carried down the route to the Molson Centre (which has since been renamed the Bell Centre). Their first game at the new venue was against the New York Rangers, a game which the Canadiens won.

Example Input: Question: When was the person who designed the palace facades in the Birks building born? Passage:Birks, a company that designs, manufactures and retails jewellery, timepieces, silverware and gifts, acquired the building in September 1912. The building was significantly reworked in 1912 to accommodate the jewellery store. The rework added distinctive Renaissance Revival palace facades designed by Percy Nobbs, featuring terracotta, granite, bronze and Tyndall stone. Above the third-floor openings are six terracotta medallions depicting the sources of the materials used by jewellers, with a seventh medallion on the north facade. These medallions depict turquoise (representing semi-precious stones), an elephant (representing ivory), a Kimberley Negro] searching for diamonds, a man diving for pearls, an oceanic wave delivering the riches of the sea (mother-of-pearl, coral and a tortoise shell), a precious metal-smelting gnome, and a silversmith surrounded by the tools of his trade. Above the medallions is a frieze depicting such characters and places as King Solomon, the Queen of Sheba, gates of Jerusalem, Hiram, king of Tyre, Negroes and an Indian, and the three wise men giving and receiving gifts. $150,000 of alterations to the ground-floor show-window area in 1951 included a granite base and Tyndall stone facings surrounding the solid bronze show windows, as well as corner columns and vestibule walls lined with Travertine marble. The building was the Winnipeg showpiece for Birks for nearly eighty years. By 1991, the basement, first, second and third floors had all been substantially altered by the Birks Company, leaving only the fourth floor of dormitories unaltered from the YMCA era. Birks continued in this building until the 1987 when it moved to Portage Place.
