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.

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

New input: Question: Do people still use the Castilian language? Passage 1:In 1479, the Lord of Béarn, Francis Phoebus, inherited the Kingdom of Navarre, across the Pyrenees to the southwest. The two sovereign principalities remained in personal union until their extinction. Béarn went on to be ruled by Henry II of Navarre, who inherited it from his mother. In 1512, the Kingdom of Navarre was almost entirely occupied by Spain; only Lower Navarre, north of the Pyrenees escaped Spanish permanent occupation. The Bearnese monarchs extended the use of Occitan to Navarre after 1512, despite the fact that it was not the vernacular there, where Basque was the tongue of the people. The Estates of Navarre convoked in 1522 (or in 1523, according to other sources) kept records in Occitan, as did the Chancery of Navarre created in 1524. When Henry II revised the Fueros of Navarre in 1530, he had them translated from Castilian into Occitan.
 Passage 2:Dasharatha was the king of Ikshvaku dynasty who ruled Ayodhya. He had four princes Rama, Lakshmana, Bharata and Shatrughna. Janaka ruled Videha. His daughter Sita was married to Rama. Sita was kidnapped by Ravana, who took her to his kingdom Lanka. During the search for Sita, Rama and Lakshmana meet Sugriva and Hanuman. Sugriva, the king of Vanara clan was removed from his throne of Kiskindha by his brother Vali(He later become Jain Monk and attained Moksha). Rama and Lakshmana helped Sugriva get back his kingdom. They, along with the army of Sugriva marched towards Lanka. Vibhishana, Ravana's brother tried to persuade him to return Sita. However, Ravana did not agree. Vibhishana allied with Rama. There was a war fought between the armies of Rama and Ravana. Lakshmana kills Ravana in the end(deviating from the Ramayana where the hero Rama slays Ravana) and Vibhishana becomes the king of Lanka. Rama and Lakshmana return to Ayodhya. Rama had around eight thousand wives among whom Sita was the principle consort(in the Hindu epic , Rama has only one wife Sita), where as Lakshmana had around sixteen thousand wives in which Prithvisundari was his principle consort(in the Hindu epic, he had only one wife, Urmila). After Lakshmana's death, Rama becomes a monk. He attains Kevala Jnana and subsequently moksha. Lakshmana and Ravana, on the other hand, go to hell. Sita was born in heaven.
 Passage 3:Sir Francis Pettit Smith of Kent invented the screw propeller. Faversham Oyster Fishery is the oldest company in the world. Maidenhead Railway Bridge is known for its flat arch, built in 1839 with 39-metre spans. The Wealden iron industry in the Weald was the site of the first blast furnace in Britain in 1491, and produced much of Britain's cast iron until the 1770s. Portsmouth Block Mills were the site of the world's first metal machine tools, built for the manufacture of wooden pulleys, invented by Henry Maudslay, and the site of the world's first industrial assembly line in 1803. South Foreland Lighthouse on 8 December 1858 was the world's first lighthouse with electric light, with the first type of industrial electrical generator made by Frederick Hale Holmes, from work he had carried out with Floris Nollet of Belgium, and 36 permanent magnets. By 1880, of the ten lighthouses with electric light, five were in the UK. From the lighthouse in 1899, the first international radio broadcast to France was made. Zénobe Gramme of Belgium made a much better design in 1870 with self-excitation of magnets, and the first modern dynamo. North Foreland Lighthouse was the UK's last-manned lighthouse until 1998.
