Given the task definition, example input & output, solve the new input case.
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.
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.

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

New input case for you: Question: What countries participated in the war that started in October 1899 that Foulkes served in? Passage 1:The Talismans were designed by Armstrong Whitworth for the Ottoman Navy, but were sub-contracted to Hawthorn Leslie and Company for building. They displaced . The ships had an overall length of , a beam of and a draught of . They were powered by three Parsons direct-drive steam turbines, each driving one propeller shaft, using steam provided by three Yarrow boilers. The turbines developed a total of and gave a maximum speed of . The ships carried a maximum of of fuel oil. The ships' complement was 102 officers and ratings. The hull form was considered particularly successful and was adopted for the V and W class of 1917, arguably the peak of destroyer development at the time.
 Passage 2:Foulkes was educated at Bedford Modern School, and was commissioned into the Royal Engineers as a second lieutenant on 27 February 1894, followed by promotion to lieutenant on 27 February 1897. He served in Sierra Leone 1898–99 (later known as the Hut Tax War), for which he received the East and West Africa Medal. After the outbreak of the Second Boer War in October 1899, he was appointed on the Staff of the army in South Africa, and took part in a number of engagements and operations. He became Assistant Commissioner for the Anglo-French Boundary Commission in the East of Niger in late 1902, with the local rank of captain. After taking part in the Kano-Sokoto expedition which brought the Emirs in Nigeria under British control in 1903, he became Commander of the Ordnance Survey of Scotland in 1904. He was a member of the bronze medal-winning team for the field hockey in the 1908 Summer Olympics. He went on to be Commander of 31st (Fortress) Company in Ceylon in 1909 and Commander of 'L' Company at the Royal Engineers Depot in Chatham in 1913.
 Passage 3:Crewe manager Dario Gradi decided not to offer a contract to Symes, who instead spent a period on trial at Bradford City, which included an 8–1 pre-season friendly win over Farsley Celtic. He signed for the League One side in July 2004 with fellow former Everton trainee Steven Schumacher, with whom he lived during his spell at Bradford. Symes made his Bradford debut in a 2–1 defeat at Hartlepool United on the opening day of the 2004–05 season. Three days later he missed a late penalty which would have secured Bradford victory over Peterborough United in a game in which Symes was also booked. Symes was dropped from the first team after Bradford signed Dele Adebola. When Bradford were allowed special dispensation to sign Neil Roberts, Bradford tried to give Symes a loan transfer to Darlington but the deal was blocked by the Football League. The following month, Symes scored his first goals for Bradford when he came off the bench at half-time to score twice in a 3–1 victory over Sheffield Wednesday on 23 October 2004. They were the only goals he scored that season from just 15 games.
