You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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: Question: Are the writers that Horiguchi studied while in Belgium both French? Passage 1:In 1980, Most was appointed Andrew W. Mellon Assistant Professor of Classics at Princeton University and remained in this position until 1985. In 1982/83, he was at the American Academy in Rome. In 1985/86, he taught at the Università degli Studi di Siena, from then until 1987 as visiting professor at the University of Michigan. In 1987, he followed a call from the Universität Innsbruck, becoming Ordentlicher Universitätsprofessor für Klassische Philologie und Altertumskunde. In 1988/89, he was a fellow at the Wissenschaftskolleg zu Berlin. In 1991, Most moved to a full professorship for Ancient Greek language and literature at the Ruprecht-Karls-Universität Heidelberg, where he taught until 2001. During these years, Most also was guest professor at the University of Michigan and professor at the Committee on Social Thought at the University of Chicago. In 1994, Most was the first classicist to receive the Leibniz-Preis of the Deutsche Forschungsgemeinschaft. Since 2001, he is teaching as Professor of Ancient Greek at the Scuola Normale at Pisa.
 Passage 2:Cungagnaq (; date of birth unknown - d. 1815) is venerated as a martyr and saint (as Peter the Aleut; ) by some jurisdictions of the Eastern Orthodox Church. He was allegedly a native of Kodiak Island (Alutiiq or Sugpiaq), and is said to have received the Christian name of Peter when he was baptized into the Orthodox faith by the monks of St Herman's missionaries operating in the north. He is purported to have been captured by Spanish soldiers near "San Pedro" and tortured and killed at the instigation of Roman Catholic priests either there or at a nearby location. At the time identified for his death, California was Spanish territory, and Spain was worried about Russian advances southwards from Alaska. Hubert Howe Bancroft, in his multi-volume History of California, only notes that, in connection with an incident wherein a Russian fur-hunting expedition was taken into custody after declining to leave San Pedro; one Russian source accused "the Spaniards of cruelty to the captives, stating that according to Kuskof’s report one Aleut who refused to become a Catholic died from ill-treatment received from the padre at San Francisco."
 Passage 3:In 1911, Horiguchi left school to accompany his father on overseas postings and during the next 14 years overseas he became fluent in French (assisted by his Belgian stepmother) and interested in French literature, particularly the novels and poetry of the Symbolist movement. He first spent over a year in Mexico, where he was diagnosed with tuberculosis, causing Horiguchi to abandon his father's hope that he become a diplomat, and he devoted his time to writing verse and translation of French works instead. He was in Mexico during the Mexican Revolution, and it was also during this time that he was drawn to Parnassianism as a style of verse. In 1913, the family relocated to Belgium, via Siberia. While in Belgium, he studied the works of Paul Verlaine and the works of the Symbolist movement, including the works of Remy de Gourmont. He subsequently lived for brief periods in Spain, Paris, Brazil and Romania and maintained correspondence with Marie Laurencin and Thomas Mann, whose works he also translated while recuperating at a sanatorium in Switzerland.
