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-Lo 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 (18941973) 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 was the rank of the man Hope served under in the Flanders Campaign? Passage 1:The East Lost Angeles freeway system and the East Los Angeles Interchange serve as an important center for the Los Angeles freeway network. It is also known for being the cause of displacing countless Mexican Angeleno communities, as 19 percent of East Los Angeles is intertwined with freeways. The freeway system grew as multiple freeways were built over two decades: the Santa Ana (5) Freeway (1944), the Hollywood (101) Freeway (1948), the San Bernardino (10) Freeway (1953), the Santa Monica (10) Freeway (extended to the East Los Angeles Interchange in 1961), the Long Beach (710) Freeway (1961), and the Pomona (60) Freeway (1965).Boyle Heights and neighboring communities protested against the first construction phases of the freeways. Community leaders rallied together to fight for their neighborhoods as they circulated petitions and organized public hearings. The construction of the freeways started as scheduled despite the resistance. The numerous freeways in this era displaced many East Los Angeles residents as they had their homes and property seized. Schools, churches, and community parks were also lost from construction. One notable structure lost in Boyle Heights was Saint Isabella Church and the Catholic elementary school. The loss of Hollenbeck Park was also a devastation to the community, since there was already a shortage of parks in the area. The Divide of Highways again justified the loss of communities by contending that residents would save time using the new freeways. Boyle Heights was a densely populated area because of low mortgages that were enjoyed by Mexican Angelo families. When families were forced to give up their homes they struggled to find homes that matched in affordability. Some families were also displaced in gang ridden areas and further from the freeways that they never used. The remaining residents in the area also still suffer the consequences of the construction of the surrounding freeways. Residents are now separated from parts of the community and face many effects of the area's air pollution caused by vehicles.
Passage 2:Hope joined the Scots Brigade as a cadet in 1778. The Brigade, in the service of the Dutch Republic, was then stationed at Bergen op Zoom and later moved to Maastricht. He had reached the rank of Captain when like other officers he left the Dutch service in 1782 during the Fourth Anglo-Dutch War and was on half-pay until 29 September 1787, when he joined the 60th Foot (Royal American Regiment), but the regiment was reduced and he was briefly on half-pay again before joining the 13th Light Dragoons on 30 June 1788. In February 1793, shortly after the French Revolutionary War had begun, Hope served as aide-de-camp to Sir William Erskine in the Flanders Campaign. On 25 March 1795, a few days after Erskine's death, Hope was promoted to major in the 28th Light Dragoons, becoming lieutenant-colonel of that regiment on 20 February 1796. Sent to the Cape Colony, the 28th, under Hope's command, helped to rebuff a Dutch attempt in August, to reclaim the colony.
Passage 3:Emmanuel was born on 2 March 1989 in Southend-on-Sea, a seaside resort town in Essex, England. Emmanuel is the second child of a half Dominican (Dominiquais) and half English mother, and a father of half-Saint Lucian and half English descent. Emmanuel demonstrated an affinity for the arts at an early age; she recalled that her mother first took notice of her passion and desire to become an actress during Emmanuel's attendance at the independent St Hilda's School (now closed) and later grammar Westcliff High School for Girls. In an interview with the New York Daily News, she commented, "When I was 3, [I'd] always cause drama that my mum decided maybe I should channel it properlyso she started me on acting, singing and dancing classes". At the age of 10, she played Young Nala in the West End production of the musical The Lion King.
