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: How old was Bela Von Kehrling when Hungary lost their first semifinal to Great Britain? Passage 1:On 11 November, Diversity conducted several hours of signing autographs and posing for photographs with thousands of fans at The Galleria Shopping Centre in Hatfield, Hertfordshire. Afterwards, they hosted a prize-giving ceremony on stage and performed their "Michael Jackson" dance routine. They performed another Michael Jackson tribute at the MOBO award ceremony. Diversity "launched" Christmas at Lakeside on 1 November, where they took two members of the audience on-stage for a dance-off. There was a competition held in November, and a hundred people won a meet and greet with Diversity on 19 November at The Glades in Bromley. On 7 December, Diversity performed on the Royal Variety Performance, hosted in Blackpool and shown on ITV across the UK on 16 December. On the show Got to Dance Warm Up, they presented their Westfield Shopping Centre FlashMob, sponsored by T-Mobile.
 Passage 2:Hungary competed in its first Davis Cup in 1924 and was stuck in the first round for five years (not counting an automatic bye). They broke the curse with the first and convincing 5–0 win against Norway realized by Béla Von Kehrling in the major part. In 1929 they cruised to their first semifinal losing to Great Britain in a close 3–2 (two singles absolved by Von Kehrling) falling only in the fifth rubber. It took another 20 years to relive the success in 1949 (including the five-year vacancy period during the Second World War) this time losing to France in the semis. The core of the team was 1947 French Open champion József Asbóth. In 1956 Hungary was absent from the Cup because of the Hungarian Revolution of 1956. In 1966 a record attendance visited the Hungary-Great Britain quarterfinal in Budapest, where a crowd of 20,000 spectators supported the András Szikszay-István Gulyás Davis Cup team during the four-day tie. A tough weekend started on Saturday 14 May for the multiple champions Brits, who had three-time Major semifinalist Mike Sangster losing their first match in five sets to István Gulyás. They turned to 2–1 on the same day but on Sunday András Szikszay also defeated Sangster leaving the decision to the fifth final tie, which was postponed to Monday. In a four set match Gulyás started well taking the first one 18–16, but Roger Taylor finished in three easier sets. English team captain Headley Baxter remarked that although they won they hadn't been forced into such a tough fight for years. Just two weeks later Gulyás had his first and lone Grand Slam final in the French Open losing only to Tony Roche of Australia.
 Passage 3:McIlroy was born in Lambeg, County Antrim and he was introduced to football at an early age as his father, Harry played for Lisburn Distillery and his uncle, Willie played for Portadown. After leaving school McIlroy played for Glentoran before joining Burnley in March 1950 for £7,000. He soon cemented his reputation as one of the finest scheming inside forwards since World War II. He was dubbed as the 'Brain' of Burnley and was a very composed passer of the ball only releasing it when he was sure of finding a teammate. His neat footwork made him a crowd favourite at Turf Moor and indeed for the Northern Ireland national team where he made 55 caps. He helped Burnley win the First Division in 1959–60 and reach the FA Cup Final in 1962, losing 3–1 to Tottenham Hotspur. After 497 matches for the "Clarets" scoring 131 goals, McIlory was allowed to leave for Stoke City for a cut price £25,000, which came as a shock to the Burnley fans who branded chairman Bob Lord 'insane'.
