Example Input: Question: What man was the lead guitarist for the shortest amount of times? Passage:The Yardbirds are an English blues rock band from London. Formed in May 1963, the group originally included lead vocalist Keith Relf, lead guitarist Anthony "Top" Topham, rhythm guitarist Chris Dreja, bassist Paul Samwell-Smith and drummer Jim McCarty. In October, Topham was replaced by Eric Clapton. He remained until 13 March 1965, when he left due to creative disagreements. Clapton recommended Jimmy Page to replace him, but he declined and Jeff Beck took over. Page later joined on bass the following June, after Samwell-Smith abruptly quit; Dreja later took over the role, allowing Page to join Beck on guitar. This lineup was short-lived, however, as Beck left in November 1966. The group continued as a four-piece until July 1968, when Relf and McCarty left due to creative differences, primarily with Page. Dreja initially remained, but by August Page formed a new group with vocalist Robert Plant, bassist John Paul Jones and drummer John Bonham, who later renamed themselves Led Zeppelin.

Example Input: Question: Which national team that withdrew on a short notice after the home nations refused to participate was established first? Passage:After the All Blacks tour, amid a time where prominent California colleges and universities were transitioning back to playing American football from rugby union, no further matches were held. However, after organizing a team for a successful tour of British Columbia in early 1920, the California Rugby Union successfully petitioned the United States Olympic Committee (USOC) to enter a team at the 1920 Summer Olympics in Antwerp, Belgium. The USOC declined to provide any funding for this team; in June 1920, the Amateur Athletic Union agreed to pay for the team's expenses. After each of the home nations declined to send a team to the Games on account of scheduling conflicts with their domestic competitions, and the teams from Romania and Czechoslovakia withdrew from the Games on short notice, the Olympic rugby union competition was reduced to a single match between the United States and France. After a scoreless first half, the United States won this match by a score of 80. Following the Olympics, the French Rugby Union invited the American team to tour France. Sixteen members of the team that competed in the Olympics traveled to France and played three uncapped matches against regional opposition from the southeast, south, and southwest of France; each resulted in a victory for the Americans. A final match against the French national team was held on October 10, 1920 in Paris, resulting in a 145 defeat for the Americans. Upon returning to the United States, the team was disbanded. Charles Tilden served as team captain during the 1920 Olympics and the tour of France that followed. Daniel Carroll, veteran of the 1913 team, served as player-coach in 1920; he was inducted into the World Rugby Hall of Fame in 2016.

Example Input: Question: How many professional boxers did Garcia train? Passage:Despite being forced to retire from pro boxing Diaz kept in shape by lifting weights at a local gym. The gym owner was impressed with Diaz physique and work ethics and recommended he become a luchador. Diaz was originally trained by Ray Carrasco and later also trained under Rogelio de la Paz, Genaro Contreas, Raul Rojas and Daniel Garcia; the latter would later be famous under the name of "Huracan Ramirez". Diaz made his professional wrestling debut in 1954, using the ring name "El Pelon" (Spanish for "Baldy") Chato Diaz, then later on worked under names such as "Indio" Mendoza, El Rayo Rojo and El Hombre del Rayo Rojo. He also worked for a while as an enmascarado (masked) character called Gargantua between 1954 and 1955. In 1955 Diaz came up with the ring name "Ray Mendoza" after his mentor Ray Carrasco and his wife's maiden name Mendoza. As Mendoza he quickly forged a very effective Rudo character ("bad guy") by using well developed physique and charisma to create a ring character that the fans loved to hate. In 1956 Mendoza began working for Salvador Lutteroth's Empresa Mexicana de Lucha Libre (EMLL), the world's oldest and Mexico's largest wrestling promotion. He made his debut at EMLL's main arena Arena Coliseo in February, 1956 in a Battle Royal that also included EMLL headliners Gory Guerrero, El Santo, Cavernario Galindo, Blue Demon and Black Shadow, a match that immediately established him as someone who Lutteroth saw potential in. In EMLL Mendoza struck up a friendship with Rene Guajardo and Karloff Lagarde out of the ring and a "partnership in crime" in the ring as the three became one of the most hated trio in lucha libre at the time. The three drew full houses all over Mexico, setting box office record after box office record as they faced tecnicos(good guys) such as El Santo, Rayo de Jalisco or Blue Demon. They also had a very financially successful feud with Los Espantos (Espanto I, Espanto II, and Espanto III) in what at the time was a rare rudo vs. rudo feud. Outside the ring Mendoza, Guajardo and Lagarde often spoke out on behalf of the wrestlers, demanding higher pay and better conditions, and since they were able to generate a lot of ticket sales EMLL officials listened to their demands.
