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.

Example explanation: The question refers to the 704th unit and task about war which is decribed by Passage 1.
Q: Question: Were Rupert of Deutz still alive when Gerberon wrote about him? Passage 1:Here he wrote a defence of the doctrine of the Real Presence against the Calvinists in the form of an apology for Rupert, abbot of Deutz (Apologia pro Ruperto abbate Tuitensi, Paris, 1669). In 1676 he published at Brussels, under the name of Sieur Flore de Ste Foi his Miroir de la piété chrétienne, an enlarged edition of which appeared at Liège in the following year. This was condemned by certain archbishops and theologians as the repetition of the five condemned propositions of Jansen, and Gerberon defended it, under the name of Abbé Valentin in Le Miroir sans tache (Paris, 1680). He had by this time aroused against him the full fury of the Jesuits, and at their instigation a royal provost was sent to Corbie to arrest him. He had, however, just time to escape, and fled to the Low Countries, where he lived in various towns. He was invited by the Jansenist clergy to Holland, where he wrote another controversial work against the Protestants: Défense de l'Église Romaine contre la calomnie des Protestants (Cologne, 1688–1691). This produced unpleasantness with the Reformed clergy, and feeling himself no longer safe he returned to Brussels. In 1700 he published his history of Jansenism (Histoire générale du Jansénisme), considered a dry work, by which, however, he is best remembered. He adhered firmly to the Augustinian doctrine of Predestination, and on 30 May 1703 he was arrested at Brussels at the instance of the archbishop of Mechelen, and ordered to subscribe the condemnation of the five sentences of Jansen. On his refusal, he was handed over to his superiors and imprisoned in the citadel of Amiens and afterwards at Vincennes. Every sort of pressure was brought to bear upon him to make his submission, and at last, broken in health and spirit, he consented to sign a formula which the Cardinal de Noailles claimed as a recantation. Upon this he was released in 1710. The first use he made of his freedom was to write a work (which, however, his friends prudently prevented him from publishing), Le vain triomphe du cardinal de Noailles, containing a virtual withdrawal of the compulsory recantation.
 Passage 2:In the 1998 championship, led by Mayo-born manager John O'Mahony, Galway won their first round encounter with Mayo, before overcoming Leitrim by 1-16 to 0-05 in the semi-final. The first final ended as a draw, 11 points apiece with Roscommon, but Galway won the replay in Hyde Park. In the semis, Galway came up against Ulster champions Derry, and won by 0-16 to 1-09. In the final the team faced a Kildare team that had just beaten the previous year's champions, Kerry, and were coached by 8 time All-Ireland winning manager Mick O'Dwyer. Galway went into the final as underdogs, but outstanding performances from Ja Fallon and Michael Donnellan in that match, along with a superbly taken goal from a young Padraig Joyce, helped Galway overcome the Lilywhites by 1-14 to 1-10. Captain Ray Silke lifted the Sam Maguire, and Galway became the first Connacht team in 32 years to win an All-Ireland title.
 Passage 3:In 1895, the British government authorized Kitchener to launch a campaign to reconquer Sudan. Britain provided men and matériel while Egypt financed the expedition. The Anglo-Egyptian Nile Expeditionary Force included 25,800 men, 8,600 of whom were British. The remainder were troops belonging to Egyptian units that included six battalions recruited in southern Sudan. An armed river flotilla escorted the force, which also had artillery support. In preparation for the attack, the British established an army headquarters at the former rail head Wadi Halfa and extended and reinforced the perimeter defenses around Sawakin. In March 1896, the campaign started as the Dongola Expedition. Despite taking the time to reconstruct Ishma‘il Pasha's former gauge railway south along the east bank of the Nile, Kitchener captured the former capital of Nubia by September. The next year, the British then constructed a new rail line directly across the desert from Wadi Halfa to Abu Hamad, which they captured in the Battle of Abu Hamed on 7 August 1897. (The gauge, hastily adopted to make use of available rolling stock, meant supplies from the Egyptian network required transshipment via steamer from Asyut to Wadi Halfa. The Sudanese system retains the incompatible gauge to this day.) Anglo-Egyptian units fought a sharp action at Abu Hamad, but there was little other significant resistance until Kitchener reached Atbarah and defeated the Ansar. After this engagement, Kitchener's soldiers marched and sailed toward Omdurman, where the Khalifa made his last stand.
