Example Input: Question: Which city was larger the year Cowan was born, Braeholm or Los Angeles? Passage:Charles Edward Cowan (June 19, 1938 in Braeholm, West Virginia – April 29, 1998 in Los Angeles, California) was an American football offensive tackle who played fifteen seasons in the National Football League with the Los Angeles Rams from 1961 to 1975. Cowan was a huge intimidating presence on the left of Tom Mack, a member of the Pro Football Hall of Fame, from 1966 to 1975, forming a potent left side of the offensive line, with help from Ken Iman at center from 1965 to 1975. In that 1961 to 1975 span, the Rams made the playoffs 5 times (1967,1969,1973,1974,1975), reaching the NFC championship game of the 1974-75 NFL playoffs and the 1975-76 NFL playoffs, but losing to the Minnesota Vikings and to the Dallas Cowboys, respectively. In the 1974 divisional round, the Rams defeated the Washington Redskins, as Cowan was successful against the opposing the right defensive end Verlon Biggs. In the 1975 divisional round, Doug France started in his place as the Rams defeated the St. Louis Cardinals. Cowan came back to play against the Cowboys, his final game, as the Rams could not get past them. Cowan was replaced by Doug France in 1976.

Example Input: Question: Who did Manuel's uncle run against for the mayorship of Ciales? Passage:Natal was born into a family with strong ties to the local politics. His maternal uncle, Javier Albelo Matos, served as a candidate for the mayorship of Ciales the 2000 general election, while his paternal grandfather was an activist for the Partido Popular Democratico (PPD). He studied at Colegio Espíritu Santo in Hato Rey, where he was president of the Student Council. Natal obtained a bachelor's degree from Cornell University in 2008, where he was president of the Puerto Rican Student Association. He did not expect to be accepted by the institution, having applied to study in it as a protocolary measure. When the acceptance letter was received, Natal was surprised and this event triggered a period of adaptation. He offered a speech at his graduation in his role of class president. After returning to Puerto Rico, Natal received a juris doctor from the University of Puerto Rico School of Law in 2011, also serving as president of the student council during his tenure. After graduating from Cornell, Natal became a key figure in a series of strikes held at the University of Puerto Rico in protest of a quota being introduced to the students. Consequently he became involved with the Popular Democratic Party and participated in an internal election for the presidency of the party's National Youth organization. After completing his juris doctor Natal opened his own lawfirm and worked for Charlie Hernández and Luis Vega Ramos, prominent members of the free association movement. In 2013, Natal was named director of the House of Representatives of Puerto Rico Commission on the Judiciary.
