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.

Let me give you an 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.

Question: What type of writings is the alphabet that the Arabic manuscipt is written in used for? Passage 1:"Secret Love" is a song composed by Sammy Fain (music) and Paul Francis Webster (lyrics) for Calamity Jane, a 1953 musical film in which it was introduced by Doris Day in the title role. Ranked as a number 1 hit for Day on both the Billboard and Cash Box, the song also afforded Day a number 1 hit in the UK. "Secret Love" has subsequently been recorded by a wide range of artists, becoming a C&W hit firstly for Slim Whitman and later for Freddy Fender, with the song also becoming an R&B hit for Billy Stewart, whose version also reached the Top 40 as did Freddy Fender's. In the U.K., "Secret Love" would become the career record of Kathy Kirby via her 1963 remake of the song. The melody bears a slight resemblance to the opening theme of Schubert's A-major piano sonata, D.664.
 Passage 2:The Book of Joshua, sometimes called the Samaritan Chronicle, is a Samaritan chronicle so called because the greater part of it is devoted to the history of Joshua. It is extant in two divergent recensions, one in Samaritan Hebrew and the other in Arabic. The editio princeps is a published an Arabic manuscript written in the Samaritan alphabet, with a Latin translation and a long preface by T. W. Juynboll (Leyden, 1848). The Samaritan Hebrew version was published in 1908 by Moses Gaster. Though based on the Hebrew canonical Book of Joshua, it differs greatly from the latter in both form and content and the Samaritans ascribe no canonical authority to it. The author, who was of a much later period, amplified the Biblical narratives by weaving into them legends of a later date and developing the narratives themselves, at the same time altering certain statements in accordance with Samaritan views on history. Alterations that emphasize the Samaritan belief in the sanctity of Mount Gerizim, the site of the Samaritan temple, appear throughout the text; for example, an expanded passage calls Gerizim "the chosen place" and a description of the temple being built there follows the conclusion of the conquest of Canaan. It is divided into fifty chapters, and contains, after the account of Joshua, a brief description of the period following Joshua, agreeing to that extent with the Book of Judges. Then follow histories of Nebuchadnezzar, Alexander the Great, and the revolt against Hadrian; it ends with an incomplete account of Baba Rabba.

After high school, he attended DePauw University, where he played basketball and earned a degree in economics. He made the all-conference team multiple times and was a three-time Academic All-America nominee. He transitioned into coaching after quitting his job at Eli Lilly and Company, joining the basketball program at Butler University as a volunteer prior to the 2000–01 season. He was promoted to a full-time assistant coach the following season. After five seasons in the role, he assumed the position of head coach on April 4, 2007, after Todd Lickliter left to coach the Iowa Hawkeyes. In his first year, Stevens led Butler to 30 wins, becoming the third-youngest head coach in NCAA Division I history to have a 30-win season.
