Example input: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage 1: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Passage 2: John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club – the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

Q: Question: What was Hereford United's record the year that O'Kelly replaced Jamie Pitman as manager? Passage 1:On 5 March 2012, O'Kelly was appointed manager of Hereford United, replacing Jamie Pitman, who stayed on at Edgar Street as a coach. He took charge with the club two places and two points above the League Two relegation zone, and signed a contract until the end of the 2011–12 season. On taking charge he said "It's my first job as manager but what better team to start with. We've got 12 games to show and prove to people just what we can do." He got his first point in charge at the club the following day, when his side squandered a two-goal lead to draw 2–2 with Macclesfield Town at Moss Rose. Four days later they beat Morecambe 1–0 at the Globe Arena, further boosting their chances of survival. He later signed full-back James Chambers and winger James Baxendale on loan from Doncaster Rovers. To avoid relegation on the last day of the campaign, the "Bulls" needed to beat Torquay United and hope Burton Albion could avoid defeat at home to Barnet. Chairman David Keyte said that he should have appointed O'Kelly earlier in the season. His team won a futile 3–2 victory, as a win for Barnet sent Hereford back down to the Conference. He was asked to remain in charge for the subsequent Conference campaign, but declined the offer.
 Passage 2:After leaving school Hubbick worked as a coal miner. In his free time he played football for Jarrow, Blyth Spartans and Spennymoor United before signing for professional club Burnley in 1935. Hubbick made his debut for Burnley on 19 October 1935 in a 1–0 win over Nottingham Forest and went on to make 32 appearances for the club that season. He scored his first goal for the club in a 2–2 draw with Manchester United on 10 April 1936. Hubbick kept his place in the side going into the 1936–37 season and missed only one match in the first five months of the campaign. He played his last Burnley match on 6 February 1937 in a 3–1 defeat to Southampton at Turf Moor. In February 1937, he left Burnley and joined Bolton Wanderers, moving up from the Second Division to the First Division.
 Passage 3:After starting his career in the youth set-up at Bradford City, Cleverley joined Manchester United at the age of 12. Between 2007 and 2009 he played for Manchester United's reserve team, and occasionally in first-team friendly matches. Cleverley was loaned to League One club Leicester City at the start of 2009, for whom he made his first Football League appearances, helping the team secure the League One title and promotion to the Championship. He spent the 2009–10 season on loan with Watford in the Championship, where he scored 11 goals in 33 league matches and was voted as their Player of the Season. On 31 August 2010, he joined Wigan Athletic on a season-long loan, where he scored four goals in 25 appearances and helped them to avoid relegation on the final day of the season. He returned to Manchester United for the start of the 2011–12 season and made his first competitive appearance in the FA Community Shield victory against Manchester City. He won the Premier League with Manchester United in 2013.
