Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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.

Reason: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this instance: Question: Who were the Three Witnesses to the Book of Mormon? Passage 1:Born near Mehoopany, Wyoming County, Pennsylvania, Harris was the son of Emer Harris and Deborah Lott. He was a nephew of Martin Harris, one of the Three Witnesses to the Book of Mormon, and a descendant of Thomas Harris, companion in exile of Roger Williams, and one of the founders of Providence, Rhode Island. Harris was baptized a member of Church of Jesus Christ of Latter Day Saints in September 1842, by Milton Stow, near Nauvoo, Illinois. Harris served as a guard in Nauvoo to protect Joseph Smith against mob violence. He also served in the Nauvoo Legion and witnessed the laying of the cornerstone of the Nauvoo Temple. After being driven with other Latter-day Saints from Nauvoo in 1846, he resided temporarily in St. Louis, Missouri until 1850, when he went to Kanesville, Iowa and then to Utah.
 Passage 2:After the war he spent another eight years organising tourist services between Iraq, Persia (now Iran) and Syria for the Mesopotamian Trading Agency of Ashar, Basrah. His wife may have joined him in 1924. He returned to South Australia in 1926 with the intention of setting up a regular service between Adelaide and Darwin via Oodnadatta and Alice Springs. He conducted a demonstration run with eight men and four women in three Studebaker cars and a Thornycroft truck, leaving Adelaide on 18 May and arrived in Darwin on 3 June; left there on 7 June and returned to Adelaide on 25 June, travelling via Camooweal, Queensland and Marree, South Australia, publicised by Duncan and Fraser (agents for both Thornycroft and Studebaker) and as they were equipped with a short-wave transceiver, gave nightly reports on radio 5CL. Despite a second successful round trip that year, Bagot abandoned his idea of regular service when the Commonwealth Government turned down his application for a subsidy. He found employment with General Motors and in 1930 "Captain Bagot" as he was called by admirers (or "'Alphabetical Bagot' as he was known to the many who disliked him), founded the Citizens' League of South Australia, which opposed Unionism, Communism and the White Australia Policy as benefiting the working classes, yet also opposing Fascism. This was the time of the Great Depression and he also supported the Young People's Employment Council and the Rev. Samuel Forsyth's (1881–1960) Forsyth Industrial Colony "Kuitpo Colony" near Kuitpo Forest, which was training boys as farm workers. The Citizen's League attempted political influence by promising support to political candidates, and was a factor in the election of the Independent candidate George Connor to the Assembly seat of Alexandra in 1934.
 Passage 3:John Francis Barnett was the son of John Barnett's brother, Joseph Alfred, also a professor of music. John Francis carried on the traditions of the family as a composer and teacher. He obtained a queen's scholarship at the Royal Academy of Music, studied under William Sterndale Bennett and developed into an accomplished pianist, visiting Germany to study in 1857 and playing Mendelssohn's Piano Concerto No. 2 in D minor at a Gewandhaus concert at Leipzig in 1860. His teachers at the Conservatoire in Leipzig included the great pianist Ignaz Moscheles, who had been a pupil of Beethoven. Back in Britain, Barnett enjoyed a successful career as a pianist for some years but concentrated increasingly on composition and teaching. He became noticed as a composer with his symphony in A minor (1864), and followed this with a number of compositions for orchestra, strings and piano. His cantata The Ancient Mariner premiered at Birmingham in 1867, and another, Paradise and the Peri, in 1870, both successfully. In 1873 his most important work, the oratorio The Raising of Lazarus, was written, and in 1876 produced at Hereford. During this period, Barnett also composed several other minor cantatas and piano pieces, and he took an active part as a professor at the Guildhall School of Music and one of the founder-professors of the Royal College of Music, where his students included Marmaduke Barton.
