Example Input: Question: When did the pitcher who Bay hit a grand slam off of in September retire? Passage:Bay got off to a slow start to the 2012 season, finishing spring training with no home runs or RBI, and his regular season, which was derailed further by a broken rib suffered while making a diving catch in the April 23 game against the San Francisco Giants. When Bay returned from the DL on June 8, 2012 against the New York Yankees, he went 0-for-3 with one strikeout. He continued to go 0-for-16 in his return from the DL through June 12, before hitting a single on June 13 against the Tampa Bay Rays. In a home game against the Cincinnati Reds on June 15, Bay left the game in the second inning after crashing into the left field wall and suffering a concussion while attempting to catch a fly ball by Jay Bruce that became an inside-the-park home run. He was subsequently placed on the DL again, and returned again on July 17 against the Washington Nationals. On September 2, Bay hit a grand slam off of Miami Marlins pitcher Mark Buehrle in the first inning of a 5–2 Mets win. Bay also hit a home run off of Buehrle on September 22 in a 4–3 Mets win. Bay finished the 2012 season with a .165 batting average, 8 home runs and 20 RBI.

Example Input: Question: How many features did Brecht and Dudow work on together? Passage:Dudow was born in Zaribrod, Bulgaria (today Dimitrovgrad, Serbia). In 1922, he emigrated to Berlin with the intention of becoming an architect. He gave up this plan and began studying theatre in 1923, first under Emmanuel Reicher, and then, from 1925 to 1926, as a theatre studies student under Max Herrmann at the university. He worked with Leopold Jessner and Jürgen Fehling, served as a chorus member under Erwin Piscator, and was a director's assistant to Fritz Lang on the production of Metropolis. During this time, Dudow also ran a bookstore with his wife and worked as a foreign correspondent for a Bulgarian newspaper. In 1929, he visited the Soviet Union, where he met Vladimir Mayakovsky and Sergei Eisenstein in Moscow and eventually, Bertolt Brecht. After his return from the USSR, Dudow directed Brecht's theatrical piece, The Decision (Die Massnahme), and began his film directing career. He was commissioned by the left-wing, Soviet-German production company Prometheus-Film to direct a short film, Wie der Berliner Arbeiter wohnt (1929), as part of the documentary series Wie lebt der Berliner Arbeiter? Dudow's first feature, Kuhle Wampe (To Whom Does the World Belong?, 1932) was a collaboration with Brecht (who provided the script and helped finance the project), Hanns Eisler, and Ernst Ottwalt. It was banned because it was perceived as being politically subversive.

Example Input: Question: In what city was Adams interned in 1973? Passage:Adams was active in rioting at this time and later became involved in the republican movement. In August 1971, internment was reintroduced to Northern Ireland under the Special Powers Act 1922. Adams was interned in March 1972, on , but on the Provisional IRA's insistence was released in June to take part in secret, but abortive talks in London. The IRA negotiated a short-lived truce with the British government and an IRA delegation met with British Home Secretary William Whitelaw at Cheyne Walk in Chelsea. The delegation included Adams, Martin McGuinness, Sean Mac Stiofain (IRA Chief of Staff), Daithi O'Conaill, Seamus Twomey, Ivor Bell and Dublin solicitor Myles Shevlin. Adams was re-arrested in July 1973 and interned at the Long Kesh internment camp. After taking part in an IRA-organised escape attempt, he was sentenced to a period of imprisonment. During this time, he wrote articles in the paper An Phoblacht under the by-line "Brownie", where he criticised the strategy and policy of Sinn Féin president Ruairí Ó Brádaigh and IRA Belfast OC Billy McKee. He was also highly critical of a decision taken by McKee to assassinate members of the rival Official IRA, who had been on ceasefire since 1972.
