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: Was the castle that was surrendered to the Scots on 31 July built before Barnard Castle? Passage 1:Appleby Castle surrendered to the Scots on 31 July, whereat Lambert, who was still hanging on to the flank of the Scottish advance, fell back from Barnard Castle to Richmond so as to close Wensleydale against any attempt of the invaders to march on Pontefract. All the restless energy of Langdale's horse was unable to dislodge Lambert from the passes or to find out what was behind that impenetrable cavalry screen. The crisis was now at hand. Cromwell had received the surrender of Pembroke Castle on 11 July, and had marched off, with his men unpaid, ragged and shoeless, at full speed through the Midlands. Rains and storms delayed his march, but he knew that the Duke of Hamilton in the broken ground of Westmorland was still worse off. Shoes from Northampton and stockings from Coventry met him at Nottingham, and gathering up the local levies as he went, he made for Doncaster, where he arrived on 8 August, having gained six days in advance of the time he had allowed himself for the march. He then called up artillery from Hull, exchanged his local levies for the regulars who were besieging Pontefract, and set off to meet Lambert. On 12 August he was at Wetherby, Lambert with horse and foot at Otley, Langdale at Skipton and Gargrave, Hamilton at Lancaster, and Sir George Monro with the Scots from Ulster and the Carlisle Royalists (organized as a separate command owing to friction between Monro and the generals of the main army) at Hornby. On 13 August, while Cromwell was marching to join Lambert at Otley, the Scottish leaders were still disputing whether they should make for Pontefract or continue through Lancashire so as to join Lord Byron and the Cheshire Royalists.
 Passage 2:By the late 1960s, the Chinese restaurants and shops around Gerrard Street, Lisle Street, and Little Newport Street had evolved into "Tong Yan Kai", otherwise known as Chinatown. The general public developed a taste for Chinese food during the postwar restaurant boom. In 1963, the Zhongshan Workers' Club opened in the West End, showing films and running classes. The first Chinese New Year celebrations were held in Gerrard Street. The Overseas Chinese Service opened the first specialised agency to assist the Chinese in dealing with the host society by offering a translation and interpreting service. In the 1970s and 1980s, many ethnic Chinese who had settled in Vietnam for generations were forced to leave as "boat people" following the Vietnam War. Many settled in Lewisham, Lambeth, and Hackney, as well as elsewhere in the UK. The 1980s and 1990s saw a migration of academics and professionals from Chinatown to the suburbs of Croydon and Colindale. Since the 1980s, London's Chinatown has been transformed by Westminster City Council to become a major tourist attraction and a cultural focal point of the Chinese community in London. Today over 100,000 Chinese people live in London, and are more evenly dispersed throughout the city and its boroughs. Roughly a quarter of the Chinese population of the United Kingdom now live in London, mainly in the boroughs of Barnet, Haringey, Waltham Forest, Hackney, Southwark and Westminster. Mare Street in Hackney is the hub of a small Vietnamese community. The principal languages of the London Chinese community are Cantonese and Hakka (from the New Territories, Hong Kong, and Vietnam). There are also some speakers of Hokkien, Teochew and Hainanese. The Chinese from the People's Republic of China, Taiwan, and Singapore tend to speak Mandarin (or Putonghua). A large network of Chinese schools and community centres offers support and a means of passing on cultural identity from one generation to the next.
 Passage 3:After presenting Way of the Warrior to Mark Cerny of Universal Interactive Studios, Naughty Dog was signed on to the company for three additional games. In August 1994, Jason Rubin and Andy Gavin began their move from Boston, Massachusetts to Los Angeles, California. During the trip, Gavin and Rubin decided to create a 3D action-platform game, taking inspiration from the 16-bit era's best, including Donkey Kong Country, Mario and Sonic. Because the player would be forced to constantly look at the character's rear, the game was jokingly code-named "Sonic's Ass Game". The basic technology for the game and the Crash Bandicoot series as a whole was created somewhere near Gary, Indiana. The rough game theory was designed by Colorado and David Siller, the creator of Aero the Acro-Bat and . Soon afterward, Gavin and Rubin threw out their previous game design for Al O. Saurus and Dinestein, a side-scrolling video game based on time travel and scientists genetically merged with dinosaurs. After moving into the Universal Interactive Studios backlot, Gavin and Rubin met with Mark Cerny, discussed the design of the game and made an agreement to go into production. In September 1994, Gavin and Rubin decided to develop their new game for the PlayStation, after which Rubin began character design. In November 1994, Naughty Dog hired Dave Baggett, their first employee and a friend of Gavin's from the Massachusetts Institute of Technology. Together, Gavin and Baggett created the development tool "Game Oriented Object LISP" (GOOL), which would be used to create the characters and gameplay of the game. In January 1995, Rubin became concerned about the programmer-to-artist ratio and hired Bob Rafei and Taylor Kurosaki as additional artists.
