Example Input: Question: How many cups has the team Franz first played for won? Passage:Franz Burgmeier (born 7 April 1982) is a Liechtenstein retired footballer, who played as a midfielder for Vaduz in the Swiss Super League. Born in Triesen, Burgmeier was a burgeoning footballer and keen skier, until he gave up the latter sport at 16 following a serious injury. Having been a youth player for Triesen, he started his professional career with Vaduz. Burgmeier won several Liechtensteiner Cups with Vaduz, who were promoted to the Swiss Challenge League in 2001, and played in the UEFA Cup. After two unsuccessful attempts to win promotion to the Swiss Super League, Burgmeier left for Aarau in 2005. He spent only one season with Aarau before a move to the previous season's runners-up Basel in 2006. His two seasons with Basel were broken up by a loan spell with Thun, before he moved to England with Darlington in August 2008, where he played for one year.

Example Input: Question: Which national team that pull out of the Pacific Nations Cup has a longer history? Passage:The 2009 Pacific Nations Cup is a rugby union tournament held between five national sides on the Pacific Rim: Fiji, Japan, Samoa, Tonga and the Junior All Blacks. The New Zealand Māori team that won the tournament last year will no longer take part in this competition because of a decision taken by the New Zealand Rugby Union. Australia A has also decided to pull out due to a similar decision. The inaugural competition was held in 2006. This year the tournament will begin on June 12 and ends on July 3, 2009 and most of the matches will be hosted by Fiji. The awarding of the key international tournament to the Fiji Rugby Union represents a further boost to the continued development of rugby in the region. The two opening round matches will be played outside of Fiji with Samoa hosting the Junior All Blacks in Apia and Tonga entertaining the Fijians in Nukuʻalofa the following day before the tournament moves to Fiji for a 17-day festival of international rugby spread across three match venues: the ANZ National Stadium (Suva), Churchill Park (Lautoka) and Lawaqa Park (Sigatoka).

Example Input: Question: In what stadium does the team that Joe Foy was traded to currently play in? Passage:The Royals began operations with General Manager Cedric Tallis, who soon developed a reputation as the best trader in the league. The first big trade was with fellow expansion team Seattle, which brought in 1969 Rookie of the Year Lou Piniella. In their inaugural game, on April 8, 1969, the Royals defeated the Minnesota Twins 4-3 in 12 innings. Two pitching stars from the Baltimore Orioles team that won the 1966 World Series pitched for the Royals in the inaugural game: Wally Bunker threw the franchise's very first pitch, and Moe Drabowsky won the game in relief. After finishing the season in 5th place, the Royals' next trade cemented a reputation as a speedy team. Third baseman Joe Foy was traded to the New York Mets for speedy outfielder Amos Otis, who would become the Royals' first star. Further one-sided trades brought to the Royals second baseman Cookie Rojas, bullpen ace Ted Abernathy, shortstop Fred Patek, first baseman John Mayberry and left fielder Hal McRae. The Royals also invested in a strong farm system and in the early years developed such future stars as pitchers Paul Splittorff and Steve Busby, infielders George Brett and Frank White, and outfielder Al Cowens.
