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: When did Wayne Rooney start playing professionally? Passage 1:Arsenal had finished the previous season as runners-up in the Premier League, overhauled by Manchester United in the final ten weeks of the season. The club did, however, retain the FA Cup, with a 1–0 win against Southampton. Such was Arsenal's effective start to the 2002–03 campaign, manager Arsène Wenger suggested his team could remain the whole season undefeated in all competitions:It's not impossible as A.C. Milan once did it but I can't see why it's so shocking to say it. Do you think Manchester United, Liverpool or Chelsea don't dream that as well? They're exactly the same. They just don't say it because they're scared to look ridiculous, but nobody is ridiculous in this job as we know anything can happen. The team lost to Everton a month after Wenger's proclamation; teenager Wayne Rooney scored the match winner, which ended a run of 30 league games without defeat. By February 2003, Arsenal moved five points clear of Manchester United at the top of the league table, but injuries to key players, not least captain Patrick Vieira, had destabilised the team. Draws in April, coupled with a defeat to Leeds United at home, mathematically ended Arsenal's chances of retaining the title. Wenger refuted opinions from the media that their season was a failure and said:

 Passage 3:Route 67 is mostly a two-lane surface road, with a divided four-lane section in Southbury. It begins in New Milford as a 0.5 mile concurrency with US 202 as the latter leaves a concurrency with US 7. After crossing the Housatonic River into the center of town, Route 67 breaks away to the southeast. In Bridgewater, it meets the northern end of Route 133. In Roxbury, it meets the southern end of Route 199 and the western end of Route 317. It then clips a corner of Woodbury before passing into New Haven County and the town of Southbury, where it passes the northern end of Route 172 before joining US 6 for a 4 lane divided 1.6 mile concurrency leading to a junction with I-84 at Exit 15. Here, US 6 joins I-84 West and Route 67 continues to the southeast becoming a 2-lane road once again. After intersecting Route 188, it enters Oxford, where it has a junction with the west end of Route 42. In Seymour, it passes the western end of Route 313 before crossing the Naugatuck River. On the east shore of the river, it meets the Route 8 expressway at Exits 21 & 22. It then passes the northern end of Route 115 before heading into Woodbridge, where Route 67 ends at Route 63.
