Let me give you an example: 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.

Question: How long had the Russian Basketball Super League been in operation when BC UNICS was runner-up to CSKA? Passage 1:Moshe Dayan (; 20 May 1915 – 16 October 1981) was an Ottoman-born Israeli military leader and politician. He was the second child born on the first kibbutz, but he moved with his family in 1921, and he grew up on a moshav (farming cooperative). As commander of the Jerusalem front in the 1948 Arab–Israeli War, chief of staff of the Israel Defense Forces (1953–58) during the 1956 Suez Crisis, but mainly as Defense Minister during the Six-Day War in 1967, he became to the world a fighting symbol of the new state of Israel. In the 1930s, he was trained by Orde Wingate to set traps for Palestinian-Arabs fighting the British and he later lost an eye in a raid on Vichy forces in Lebanon. Dayan was close to David Ben-Gurion and joined him in leaving the Mapai party and setting up the Rafi party in 1965 with Shimon Peres. Dayan became Defence Minister just before the 1967 Six-Day War. After the October War of 1973, Dayan was blamed for the lack of preparedness; after some time he resigned. In 1977, following the election of Menachem Begin as Prime Minister, Dayan was expelled from the Labor Party because he joined the Likud-led government as Foreign Minister, playing an important part in negotiating the peace treaty between Egypt and Israel.
 Passage 2:UNICS has gone a long way towards helping Russian basketball since the club was established in 1991. Between 1994 and 1997, UNICS secured a berth in Russia's first division, and then made a smashing debut, establishing itself among the top five teams in the country. UNICS had already played in European competitions in 1997, but the new millennium happened to be a turning point for the club. The team placed second to CSKA in the Russian Basketball Super League in 2001 and 2002, the year in which it also reached the Saporta Cup semifinals, losing against the Greek club Maroussi in the semifinals. UNICS' first title was the Russian Cup in March 2003, with an electrifying 81–82 overtime victory over CSKA. UNICS' fans did not have to wait long to see their team win a European title, too. Kazan hosted the FIBA Europe League final four, which was eventually named the FIBA EuroChallenge, in April 2004, and UNICS made sure of its opportunity. UNICS signed Saulius Štombergas, Eurelijus Žukauskas, and Chris Anstey, and then won its regular season group, and advanced to the final four, which was held on its own floor, and where the club was crowned the FIBA Europe League champions. The MVP of the tournament's final four, Martin Müürsepp, scored 22 points, in an 87–63 win over Maroussi, in the title game. By the 2005–06 season, UNICS went one level up, and made its ULEB Cup (later named EuroCup) debut, where they tied the best regular season record in the competition's history. However, things turned south quickly, as UNICS lost at home against Roma, for the only time all season, in the tournament's eighth finals’ second leg, and crashed out earlier than expected. UNICS got stronger for the next season, keeping the core group of the previous season's side, while adding Darjuš Lavrinovič to reunite with his twin brother Kšyštof Lavrinovič, in a twin-towers set full of talent. The team made it to the ULEB Cup semifinals, before losing to the eventual league champs Real Madrid. It also returned to the Russian League finals, losing against perennial champion CSKA.
