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: Approximately how many members were there in the II Royal Bavarian Corps? Passage 1:Von Maillinger was born in Passau. After passing his company officer career, at last in the Generalquartiermeister staff in Munich, he was transferred to the General Command in Munich as major of the general staff. The first time, he served for the war ministry, he was ordered by Von Lüder. In 1863 he became head of department at the war ministry. Also he was adjutant of Eduard von Lutz, as well as representative of him at the Landtag. In 1865 he was advanced to Oberstleutnant, in 1866 he Oberst. Thenceforward he was commander of the 7th Royal Bavarian Infantry Regiment and deputy of Von Lutz. In 1869 he became major general and commander of the 8th Royal Bavarian Infantry Brigade. One year after that, he was advanced to lieutenant general, and led the 2nd Royal Bavarian Division during the campaigns of the Franco-Prussian War, which stood in France as part of the Bavarian occupation army until 1873. After he returned to Bavaria, he became commander of the II Royal Bavarian Corps. During the period, when he served as war minister, he was advandced to General der Infanterie in 1877 and got the main ownership of the 9th Royal Bavarian Infantry Regiment "Wrede" The psychiatrist and neurologist Prof. Dr. Dr. Dres. h.c. Heinz Häfner says, Maillinger's withdrawal from his ministry post was caused by Ludwig II's reputed sexual abuse of young cavalrists (chevau-légers). Ritter von Maillinger became a member of the Reichsrat in 1888. He died in Bad Aibling. The Maillingerstraße in Munich is named in honor of him.
 Passage 2:Maryam Bayramalibeyova was the daughter of Azerbaijani historian and journalist Teymur Bayramalibeyov and his wife Shirin (née Talyshinskaya), a Russian-educated Talysh-Azerbaijani who translated a number works by classical Russian writers into Azeri and was famous for promoting Western culture in Lankaran and the neighbouring regions. In 1906 Maryam Bayramalibeyova was accepted to the Empress Alexandra Russian Muslim Boarding School for Girls in Baku and 7 years later, to Saint Nina's Secondary Boarding School. In 1917, she graduated from Saint Nina's with honours and was admitted to study medicine at Moscow State University. However, after the October Revolution, being a daughter of an upper-middle class literatus Bayramalibeyova considered her life to be in danger and returned to Lankaran (eventually she did manage to get a post-secondary education receiving an Honours B.A. in law from Baku State University later in 1931). In her native city in 1917, she established the first all-girls secular school (named Uns) in the entire uyezd (administrative unit in Czarist Russia) with the help of Teymur Bayramalibeyov, and became its first principal. The Bayramalibeyovs visited many families in Lankaran encouraging them to send their daughters to Uns. The courses were taught in the Russian language. In order to promote the arts, Maryam Bayramalibeyova organized drama, choir, and musical clubs in the school, which apparently was a success as two of her students later became prominent Azerbaijani actresses and one became a renowned mugham singer. In 1919, Bayramalibeyova founded the Lankaran Women's Charity Association.
