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-Lo 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 (18941973) 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: In what year did Steffi Graf beat Monica Seles in the German Open? Passage 1:Graf lost an Australian Open quarterfinal to Jana Novotna, the first time she did not reach the semifinals of a Grand Slam singles tournament since the 1986 French Open. She then lost to Sabatini in her next three tournaments before winning the U.S. Hardcourt Championships in San Antonio, beating Monica Seles in the final. After losing a fifth straight time to Sabatini in Amelia Island, Florida, Graf again defeated Seles in the Hamburg final. Following her tournament victory in German Open in Berlin, Graf suffered one of the worst defeats of her career in a French Open semifinal where she won only two games against Sanchez Vicario and lost her first 60 set since 1984. At Wimbledon, however, Graf captured her third women's crown, this time at Sabatini's expense. Sabatini served for the match twice, and was two points away from her first Wimbledon title. After breaking Sabatini's serve to even the third set at 66, Graf defeated Sabatini by winning the next two games to take the match 64, 36, 86. Martina Navratilova then defeated Graf 76, 67, 64 in a US Open semifinal, the first time she had beaten Graf in four years. Graf then won in Leipzig, with her 500th career victory coming in a quarterfinal against Judith Wiesner. After winning two more indoor tournaments at Zurich and Brighton, she failed once again in the Virginia Slims Championships, losing her quarterfinal to Novotna. Soon after, she split with her long-time coach, Pavel Slozil.

His translation of Benedict Anderson's "Imagined Communities" was published in April 2001 by Kiev's "Krytyka". Victor's translation of J. K. Rowling's world bestsellers "Harry Potter and the Philosopher's Stone" (April 2002), "Harry Potter and the Chamber of Secrets" (September 2002), "Harry Potter and the Prisoner of Azkaban" (December 2002), "Harry Potter and the Goblet of Fire" (May 2003), "Harry Potter and the Order of the Phoenix" (November 2003) and "Harry Potter and the Half-Blood Prince" (October 2005) was published by Kyiv's "A-BA-BA-HA-LA-MA-HA".
Passage 3:Plucknett describes Bracton in this way: "Two generations after Ranulf de Glanvill we come to the flower and crown of English jurisprudence Bracton." Bracton was born around 1210 in Devon and had a great deal of preferment in the Church. He either derived from Bratton Fleming or Bratton Clovelly. Both villages are in Devon. It was only after his death that the family name appears as Bracton; during his life, he was known as Bratton, or Bretton. This originally may have been Bradton, meaning "Broad Town". Bracton first appeared as a justice in 1245. From 1248 until his death in 1268 he was steadily employed as a justice of the assize in the southwestern counties, especially Somerset, Devon and Cornwall. He was a member of the coram rege, also called the coram ipso rege, later to become the King's Court. He retired from this in 1257, shortly before the meeting of the Mad Parliament in 1258 at Oxford. It is unknown whether his retirement was related to politics. His leaving coincided with the onset of the notorious Second Barons' War in 1264. At that time Bracton was ordered to restore to the Treasury the large store of plea rolls (case records from previous trials) that had been in his possession. He was also forced to surrender the large number of rolls from his predecessors Martin Pateshull and William Raleigh, also known as William de Raley. It cannot be determined whether he disgraced the King or the barons in this affair, but it is speculated that some kind of political intrigue was involved. The practical result was that his major work, De Legibus et Consuetudinibus Angliae ("The Laws and Customs of England"), was left unfinished. Even so, it exists in four large volumes today. He continued to follow the assizes in the southwest until 1267. In the last year of his life he filled another prominent role, as member of a commission of prelates, magnates and justices appointed to hear the complaints of the "disinherited" those who had sided with Simon de Montfort, 6th Earl of Leicester.
