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.

Problem: Question: In what year was the National Association of the Professional Base Ball Players formed? Passage 1:The Cincinnati Red Stockings, established in 1869 as the first openly all-professional baseball team, voted to dissolve after the 1870 season. Player-manager Harry Wright, with brother George and two other Cincinnati players, then went to Boston, Massachusetts at the invitation of Boston Red Stockings founder Ivers Whitney Adams to form the nucleus of the Boston Red Stockings, a charter member of the National Association of Professional Base Ball Players (NAPBBP). The original Boston Red Stockings team and its successors can lay claim to being the oldest continuously playing team in American professional sports. (The only other team that has been organized as long, the Chicago Cubs, did not play for the two years following the Great Chicago Fire of 1871.) Two young players hired away from the Forest City club of Rockford, Illinois, turned out to be the biggest stars during the NAPBBP years: pitcher Al Spalding (founder of Spalding sporting goods) and second baseman Ross Barnes.
 Passage 2:In 1922, Mackenzie published Ancient Man in Britain, a work covering the history of Britain from Upper Paleolithic times, from a strong ethnological basis. The foreword of the book was written by Grafton Elliot Smith. The work covers the earliest settlement of Britain by the first modern humans from around 35,000 years ago during the Aurignacian (pp. 19–27). In the book, Mackenzie maintains that the Caucasoid Cro-Magnons who settled in Britain were dark haired and dark eyed, racially akin to the French Basques, Iberians and Berbers of North Africa (p. 25), who he theorised were one of the earliest representatives of the Mediterranean race. This indigenous proto-Mediterranean racial stock was later invaded by another "variety of the Mediterranean race" who initiated the Solutrean culture around 20,000 years ago (p. 50). According to Mackenzie, the Aurignacian and Solutrean peoples of Britain traded in shells with Cro-Magnons of France. They later intermingled with later arriving Caucasoid racial types, including the proto-Alpines (Furfooz race), who were brachycelphalic (broad-skulled) and a Lappid race, who had minor Eskimo phenotypic traits. Mackenzie also believed that there was a highly depigmentated racial type in small numbers in Britain during the Magdalenian, perhaps who were also blonde, who intermingled with the "dark Iberians" (p. 60). During the Neolithic, Mackenzie believed that the predominant racial type of Britain continued to be Mediterranoid: "The carriers of Neolithic culture were in the main Iberians of Mediterranean racial type" (p. 126) who traded in pearls and ores. Regarding Bronze Age Britain, Mackenzie devoted several chapters supporting his theory that traders and "prospectors" (miners) arrived in Britain c. 2500 BC, originally from the Eastern Mediterranean (pp. 98–101). This theory was initially developed by Harold Peake, who coined the term "Prospector Theory". In the scientific literature of Carleton S. Coon (1939), the theory was revived, and the Mediterraneans who colonised Britain during the late Neolithic or Bronze Age were associated with the Medway megaliths (or long-barrow Megalithic culture). Joseph Deniker earlier called these colonists "Atlanto-Mediterranean". Mackenzie believed that these Mediterraneans who colonised parts of Britain survived well into later historic periods (p. 118) and that the Mediterranean race in general was the bulk racial stock of Britain from Paleolithic through to the Neolithic and to more recent periods. They had black or brown hair, and swarthy skin "like those of the Southern Italians" (p. 126) and have survived in numerous pockets of Britain to the modern day (p. 139) despite that the later Anglo-Saxon and Norse settlement, who were fairer in appearance, Mackenzie believed their genetic input or admixture was very limited but that they subjugated the British imposing a new civilization and culture (p. 227).
 Passage 3:Ince Blundell Hall is in Georgian style. It is constructed in brick with sandstone dressings, and has an L-shaped plan. The main block faces southeast; it is in two storeys with an attic, and has a front of nine bays. Richard Pollard and Nikolaus Pevsner describe the front as being in late English Baroque style, and consider that it was "evidently inspired" by the front of Buckingham Palace, London. Between the upper storey and the attic is an entablature with a cornice and a panelled parapet. The central three bays project forward, the lower storeys are flanked by pairs of giant pilasters, and at the sides of the central doorway are giant columns. There are more pilasters at the ends of the building, and in the central three bays of the attic. All the pilasters and columns are Corinthian in style. The windows are sashes and are surrounded by architraves. The ground floor windows in the central bays have segmental heads with keystones, and those in the outer bays have friezes and pediments carried on consoles. Below the upper floor windows are panelled aprons and consoles. The central doorway has a segmental head and a keystone carved with the Blundell arms. At the corners of the front are quoins.
