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: Of Sluyter's interests, when did the event which led to America being populated by Europeans occur? Passage 1:Pope Pius X created him Cardinal Priest of Santa Maria sopra Minerva in the consistory of November 27, 1911. He was one of the cardinal electors who participated in the 1914 papal conclave, which selected Pope Benedict XV. Following the outbreak of World War I, Farley stated, "I would that peace could come by arbitration and diplomacy. It seems, however, that no permanent peace can be hoped for except through the defeat of German arms in the field or the repudiation of the Prussian autocracy by the German people themselves. Criticism of the government irritates me. I would consider it treason." He also said, "As Catholics in America, we owe unswerving allegiance to the Government of the United States, and it is our sacred duty to answer with alacrity every demand our country makes upon our loyalty and devotion." His dedication to victory in the war angered the Sinn Fein element of the New York clergy, who believed the Cardinal was bowing to anti-Irish bigots.
Passage 2:Born in Hill of Beath, Fife Durkin joined Edinburgh-based club Heart of Midlothian from local club Hill of Beath Ramblers in 1948, but did not make his Scottish Football League debut until 1951. He remained at Tynecastle Stadium until 1952, but played only sporadically, and joined Dunfermline Athletic in December of that year. In August 1953, he joined Gillingham of the Football League Third Division South. He signed for his new club on 21 August and made his Football League debut the following day in a match against Reading, during which he scored two goals in a 30 victory. He missed only one first team match between his debut and the following January, but then missed the remainder of the 195354 season. The following season, he could not gain a place in the team, managing only three appearances when key players were injured, although on his first appearance for ten months he scored a goal in a 31 victory over Newport County. He left at the end of the 195455 season to join non-league club Ramsgate Athletic of the Kent League in May 1955. No further details of his career are known.
Passage 3:Andrew Sluyter is an American social scientist who currently teaches as a professor in the Geography and Anthropology Department of the Louisiana State University in Baton Rouge. His interests are the environmental history and historical, cultural, and political ecology of the colonization of the Americas. He has made various contributions to the theorization of colonialism and landscape, the critique of neo-environmental determinism, to understanding pre-colonial and colonial agriculture and environmental change in Mexico, to revealing African contributions to establishing cattle ranching in the Americas, and to the historical geographies of Hispanics and Latinos in New Orleans. With the publication of Black Ranching Frontiers: African Cattle Herders of the Atlantic World, 15001900 (Yale University Press, 2012) and a 201213 Digital Innovation Fellowship from the American Council of Learned Societies, he has joined a growing number of scholars from multiple disciplines working from the perspective of Atlantic History and using the tools of the Digital Humanities. His latest book, Hispanic and Latino New Orleans: Immigration and Identity since the Eighteenth Century (LSU Press, 2015), co-authored with Case Watkins, James Chaney, and Annie M. Gibson, was awarded the 2015 John Brinckerhoff Jackson Book Prize by the American Association of Geographers.
