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-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.

Q: Question: How old was Bishop Francisco Marroquin when he recalled Bartolome de las Casas? Passage 1:On his second visit to Guatemala, in 1537, friar Bartolome de las Casas, O.P. wanted to employ his new method of conversion based on two principles: 1) to preach the Gospel to all men and treat them as equals, and 2) to assert that conversion must be voluntary and based on knowledge and understanding of the Faith. It was important for Las Casas that this method be tested without meddling from secular colonists, so he chose a territory in the heart of Guatemala where there were no previous colonies and where the natives were considered fierce and war-like. Because of the fact that the land had not been possible to conquer by military means, the governor of Guatemala, Alonso de Maldonado, agreed to sign a contract promising that if the venture was successful he would not establish any new encomiendas in the area. Las Casas's group of friars established a Dominican presence in Rabinal, Sacapulas and Coban, reaching as far as Chahal and including Cubulco. Through the efforts of Las Casas' missionaries the so-called "Land of War" came to be called "Verapaz", "True Peace". Las Casas's strategy was to teach Christian songs to merchant Indian Christians who then ventured into the area. In this way he was successful in converting several native chiefs, among them those of Atitlan and Chichicastenango, and in building several churches in the territory named Alta Verapaz. These congregated a group of Christian Indians in the location of what is now the town of Rabinal. In 1538 Las Casas was recalled from his mission by Bishop Francisco Marroquin who wanted him to go to Mexico and then on to Spain in order to seek more Dominicans to assist in the mission.
Passage 2:Born on the New Year's Day of 1966 at Khargapur in the Indian state of Madhya Pradesh, Sangita Mukhopadhyay completed her MSc with a gold medal and did her doctoral studies at the Regional Medical Research Center, Bhubaneswar which fetched her a Phd from Utkal University in 1998 for her thesis on immunoregulation in filariasis. Subsequently, she did the post-doctoral work at the National Institute of Immunology and, later, in U.S.A. at the University of Texas Health Science Center at Houston. On her return to India, she joined the Central Drug Research Institute in 1999 and after a short stint, moved to the Centre for DNA Fingerprinting and Diagnostics (CDFD). She later became the head of the Molecular Biology Group at the Laboratory of Molecular and Cellular Biology of the institute and holds the position of a Grade IV staff scientist. At her laboratory, she hosts many research scholars who are involved in the studies in the disciplines of cell signaling and signal transduction, immunity, macrophage biology and tuberculosis.
Passage 3:In English, ottava rima first appeared in Elizabethan translations of Tasso and Ariosto. The form also became popular for original works, such as Michael Drayton's The Barons' Wars, Thomas Heywood's Troia Britannica, or Aemilia Lanyer's Salve Deus Rex Judaeorum. William Browne's Britannia's Pastorals also contains passages in ottava rima. The first English poet to write mock-heroic ottava rima was John Hookham Frere, whose 1817-8 poem Prospectus and Specimen of an Intended National Work used the form to considerable effect. Lord Byron read Frere's work and saw the potential of the form. He quickly produced Beppo, his first poem to use the form. Shortly after this, Byron began working on his Don Juan (18191824), probably the best-known English poem in ottava rima. Byron also used the form for The Vision of Judgment (1822). Shelley translated the Homeric Hymns into English in ottava rima. In the 20th century, William Butler Yeats used the form in several of his best later poems, including "Sailing to Byzantium" and "Among School Children". So did Kenneth Koch for instance in his autobiographical poem "Seasons on Earth" of 1987. In America Emma Lazarus wrote the poem An Epistle that consists of thirty four ottava rimas. Earlier Richard Henry Wilde used the stanza in his long poem Hesperia.
