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: Was Kontinen's mixed doubles partner at Wimbledon older than his male doubles partner? Passage 1:During this time, Portugal was not part of a group of teams that were candidates to win titles, but from 2000 until this present day, the team evolved, being present in all the final stages of major tournaments, due to the presence of several world-class players such as Luís Figo, Rui Costa, Deco, Ricardo Carvalho, and Cristiano Ronaldo, who were dubbed as Portugal's golden team, who were considered as the best of the world at their time and among the best in history. Portugal's golden team helped Portugal reach the semi-finals of Euro 2000, losing 3–2 after extra time to eventual winners France, securing the second place at Euro 2004 Final after losing to Greece on home soil, as well reaching the semi-finals of the 2006 World Cup losing to finalist France, after a penalty, leading Portugal to secure the fourth place in the tournament, after losing to 3–1 to hosts Germany, thus being the best result since the 1966 World Cup. Despite losing many players of the golden team, new players such as Fábio Coentrão, João Moutinho, Nani and Pepe helped the Portuguese reach the semi-finals of Euro 2012, losing to Spain in penalties, with Cristiano Ronaldo finishing as joint top scorer of the tournament with three goals. 
 Passage 2:His good results continued in 2016 as he won the title at the Brisbane International in January with John Peers. On April–May they won the BMW Open together. At the 2016 Wimbledon Championships he reached quarterfinals of the men's doubles tournament together with Peers and the final of the mixed doubles with Heather Watson, which they won in straight sets. On July Kontinen and Peers won the German Open Tennis Championships. On August Kontinen won the Winstom-Salem Open playing with Guillermo García-López. It was Kontinen's 10th doubles title in his career. He took the victory of St. Petersburg Open with Dominic Inglot. Kontinen and Peers had a successful end for the year as they won their first Masters title at Paris Masters and the season ending ATP World Tour Finals title. Kontinen reached the top 10 in rankings as a first Finnish tennis player ever.
 Passage 3:Olson made one CART World Series start in 1983 at Road America. In 1984 he drove in three Can-Am races, an IMSA GT Championship race and two World Endurance Championship races, including the 1984 24 Hours of Le Mans where he was caught up in the debris field of his Aston Martin teammate John Sheldon's crash that killed a track worker. In 1985 he won three races with Dyson Racing in IMSA Camel GTP, the team's first, in a Porsche 962. 1986 saw Olson continue in IMSA GTP with Dyson and Preston Henn fielding his entries. That year he also competed in the 1986 24 Hours of Le Mans, co-driving a Rothmans Porsche factory 962 with Vern Schuppan. Olson was away from racing after that until 1989 when he returned with the All American Racers Toyota 88C factory team in IMSA GTP. He won two poles and finished ninth in points. 1990 would be his final year of professional racing as he finished tenth in GTP points with three poles for All American Racers in their Eagle HF89.
