In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

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: How long did the king who was painted by Jan Matejko rule Poland? Passage 1:The season began with two wins, but a run of one win in ten games then followed. In September, four of the five directors resigned, one of them (Len Cliff) stated that "the club is being run by outsiders". A new board was formed by November. Meanwhile, on 13 September the club suffered a loss of 7–3 at Gay Meadow to Shrewsbury Town, despite a Bobby Gough hat-trick – the match also saw a sending off, an attempted pitch invasion, and a £35 fine for Gordon Lee for remarks he made to referee Ricky Nicholson. Tommy McLaren then returned from injury to lead Vale on a four match winning streak that included a 2–0 win over fallen-giants Aston Villa in front of a Burslem crowd of 11,224 fans. Four straight defeats soon came after this sequence however, as Vale's form was patchy. In December, Ron Wilson left the club as he emigrated to South Africa due to his son's ill health. A 1–0 defeat at Villa Park on 16 January was the first of a nine match streak without a victory. At the end of the month Lee signed John Brodie from Northern Premier League side Bradford Park Avenue for £250. During this spell forward Sammy Morgan began to be jeered by fans after losing his scoring touch. He also began studying to be a teacher. Lee said that "I really feel some of our lads have been singled out by the boo boys. If only they realised that encouragement can lift players, things would be so much better". In February, Mark Singer resigned as chairman, and was replaced by Graham Bourne. By then the club were hovering above the relegation zone, but a record of just ten goals conceded in their final twelve games was enough to secure safety, with Brian Horton in good form.
 Passage 2:Modern history accepts this gateway as one of three constructed by Yaroslav the Wise. The golden gates were built in 1017-1024 (6545 by the Byzantine calendar) at about the same time the Saint Sophia Cathedral was erected. Mentions of an older construction, such as the one presented on a painting by Jan Matejko of king Bolesław I of Poland striking the Golden Gate with his sword during the intervention in the Kievan succession crisis in 1018, it is now regarded a legend. Originally named simply the Southern Gate, it was one of the three main entrances to the walled city, along with the Ladski and Zhydivski (Polish and Jewish) Gates. The last two have not survived. The stone fortifications stretched for only 3.5 km. The fortification of the Old Kyiv (Upper City) stretched from the Southern Gates down to what is now Independence Square and where the Lechitic Gate was located. From there, the moat followed what is now Kostyol Street, skirting St. Michael's Monastery and continuing along today's Zhytomyr Street toward the Jewish Gates (at ). From there, the fortification stretched what is now Yaroslaviv Val ("Yaroslav's Rampart") Street back to the Southern Gate.
 Passage 3:Bobby Lee Rodgers is an American musician who is currently a solo artist and leader of the Bobby Lee Rodgers Trio. He is a former member of The Codetalkers. Rodgers studied jazz and classical guitar at the University of Georgia. After his time at Georgia, Rodgers moved to Boston, where he taught jazz studies at the Berklee College of Music as their youngest instructor at age 23. Rodgers released his first solo album, Water Buffalo, in 1997 on ZC Records. In 1999, Rodgers formed The Codetalkers alongside Col. Bruce Hampton after meeting Hampton at the Variety Playhouse in Atlanta. The Codetalkers broke up in 2009, and Rodgers has since continued as a solo artist and as the leader of the Bobby Lee Rodgers Trio. On March 24, 2018, Rodgers supported the post-grunge act Bush at The Fillmore Miami. On May 5, 2018, Rodgers, along with Jimmie Vaughan and Blackfoot, supported Lynyrd Skynyrd at the MidFlorida Credit Union Amphitheatre in Tampa, Florida as part of Lynyrd Skynyrd's The Last of the Street Survivors Farewell Tour.
