You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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.

Why? The question refers to the 704th unit and task about war which is decribed by Passage 1.

New input: Question: Who managed the team that the Royals were runners-up to in the 2001-02 season? Passage 1:An important portion of the 1999 war between Yugoslavia and the NATO coalition involved combat between the Yugoslav Air Force, which was the predecessor of today's Serbian Air Force, and the opposing air forces of NATO. United States Air Force F-15s and F-16s flying mainly from Italian air force bases attacked the defending Yugoslav fighters—usually MiG-29s, which were in bad shape, due to lack of spare parts and maintenance. A total of six Yugoslav MiG-29s were shot down in 1999, of which three were shot down by USAF F-15s, one by a USAF F-16, and one by a RNAF F-16. One aircraft, according to a Serbian documentary, was hit by friendly fire from the ground. Another four were destroyed on the ground. During the course of the air war, Yugoslav anti-aircraft defenses downed a USAF F-16C and an F-117 Nighthawk, the first stealth aircraft to ever be shot down in combat.
 Passage 2:SR 126 begins in Kingsport at an intersection with SR 93 at its interchange with I-26/US 23 (Exit 4). It goes northeast as a 4-lane undivided highway (known as Wilcox Drive) and immediately has an intersection with its business route, SR 126 Bus (old Wilcox Drive), before going through neighborhoods and industrialized areas before having an interchange with Jared Drive and crossing a bridge over the South Fork Holston River and having an intersection with SR 355. SR 126 continues northeast through more neighborhoods before coming to an intersection with and becoming concurrent with SR 36 (E Center Street), where SR 126 turns southeast to become concurrent with that highway. SR 36/SR 126 then continue southeast to a y-intersection, where they turn onto Fort Henry Drive and become a divided highway. They then come to an intersection with Memorial Boulevard, where SR 126 turns east to leave SR 36 to follow that street. SR 126 becomes undivided once again as it passes through some commercial areas before coming to an interchange with SR 93, where it narrows to 2-lanes and leaves Kingsport, through it still officially remains within the city limits. SR 126 then passes through rural areas and crosses over a ridge before coming to an interchange with I-81 (Exit 66), where it officially exits the city limits of Kingsport. The highway then passes through rural areas again, now paralleling I-81, to enter Blountville, where it has an intersection with SR 75. SR 126 then enters downtown and has an intersection with SR 394. The highway then continues east through downtown before leaving Blountville and continuing east. SR 126 then passes through Walnut Hill before entering Bristol, coming to an end at an intersection with US 11W/SR 1 just south of downtown.
 Passage 3:Dillon returned to Reading in 1995 and held a number of roles within Reading's academy. He was also reserve team manager before he replaced Martin Allen as Alan Pardew's assistant in November 2001. Under the guidance of the management duo, the Royals were promoted to Division 1 after finishing as runners-up to Brighton & Hove Albion in the 2001–02 season. Pardew resigned in September 2003 and Dillon stepped in as the caretaker manager, until Steve Coppell was appointed in October 2003. At this point Dillon reverted to his role as the number two. Dillon passed his UEFA Pro Licence in 2004 and in the 2005–06 season Reading won the Championship with a record of 106 points. In their first season in the Premier League Reading finished 8th. In May 2007, Dillon followed Coppell's lead in committing himself to Reading for a further two seasons. They were relegated back to the Championship the next season and in May 2009 following the resignation of Coppell, Dillon alongside other first-team coach Wally Downes, left Reading following the team's failure to gain promotion back to the Premier League.
