Given the task definition, example input & output, solve the new input case.
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: 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.

New input case for you: Question: When did Citadel Media become Cumulus Media Networks? Passage 1:Coward was commissioned into the Royal Air Force as an acting pilot officer (on probation) on 28 January 1937. He joined No. 19 Squadron based at RAF Duxford as a pilot flying the Gloster Gauntlet, a single seat biplane. His commission was confirmed and he was regraded as a pilot officer on 16 November 1937. Having shown his artistic skill through caricatures of his comrades, he was tasked with painting the squadron badge on the canvas of the biplanes. However, after weeks of work, the Munich Crisis occurred and the biplanes, and their recently painted badges, were painted over in camouflage. His squadron was the first to be equipped with the Supermarine Spitfire, which entered service on 4 August 1938. He was promoted to flying officer on 16 June 1939. 
 Passage 2:KVOB started as KQNS-FM in September 1988, then located on 95.9 FM with an ERP of 1.3 kW. At the time, the station carried an adult contemporary format. In 1994, B-B Broadcasting bought the station from Smoky Hill Broadcasting, and the following year, the station moved to 95.5 FM and upgraded their power to 15.5 kW. By this time, the station flipped to a mainstream rock format, branded as "Star 95." In 1999, the station flipped back to adult contemporary, keeping the "Star 95" moniker. In 2004, the station began running the "Hits & Favorites" satellite feed from Citadel Media (now Cumulus Media Networks) and changed monikers to "Lite Rock 95.5". A year later, the station switched satellite feeds to Westwood One's AC feed, again keeping the "Lite Rock 95.5" moniker. In 2006, the station rebranded as "OZ 95", again keeping the AC format. In 2007, the station flipped to adult hits, branded as "Bob FM". The station was assigned the KVOB call sign by the Federal Communications Commission on December 1, 2007. A year later, the station switched to Sparknet Communications' national feed of "Jack FM", again retaining the adult hits format.
 Passage 3:The Company was founded in 1946 by Friedl Pfeifer, an Austrian ski instructor and racing champion, Walter Paepcke, a successful Chicago industrialist, Judge William E. Doyle, James J. Johnston, and H. F. Klock. Paepcke also founded cultural institutions in the city, such as the Aspen Institute and the Aspen Music Festival. The Aspen Skiing Company established the Aspen Mountain ski resort on Aspen Mountain above the town of Aspen, Colorado. The first chair lift, Lift-1, opened on December 14, 1946, and was the world's longest chairlift at the time. In 1950, the company hosted the FIS World Alpine Championships, the first international skiing competition in the United States. In the following decades, the company opened Buttermilk in 1958 and the Snowmass (originally the Snowmass-at-Aspen Ski Area) in 1967. In 1993 the company assumed ownership and operation of Aspen Highlands, which was founded in 1958 by Colorado Ski Hall of Famer: Whip Jones. Previously, Jones successfully sued Aspen Skiing before the Supreme Court for antitrust violations in Aspen Skiing Co. v. Aspen Highlands Skiing Corp.
