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: What city was Okanagan mission in? Passage 1:Eli Lequime (1811–1898) was born in France and began traveling the world in 1825 at the age of fourteen. He arrived in San Francisco in 1852 for the gold rush but soon gave up. Eli returned to France and fought in the Crimean War. He returned to San Francisco by 1856 and with his new wife, Marie Louise (née Altabagoethe) he caught a boat to Victoria, British Columbia. From there, the family caught a boat to the mainland. he had two children, Bernard and Gaston. The family panned for gold at Rock Creek which is west of Osoyoos. During Eli's time at Rock Creek, his son Gaston fell into a miner's sluice box and drowned at two years of age. Eli, Marie Louise and Bernard headed for the Cariboo with the hopes of striking it rich. On their way, Marie Louise gave birth to another son, who they named Gaston. Father Pandosy met the family on the trail and convinced them to come to Okanagan Mission with him. In 1861, Eli registered a land claim northeast of the Mission. Eli built a log home and a trading post on his new property. His store soon became the social and business hub of the area. Eli and Marie Louise had two more children at the Mission, Aminade (1866) and Leon (1870). The Lequime family had over 1,300 heads of cattle and had more than two thousand acres of land. Eli lived in the Mission Valley for twenty-seven years. When he was seventy, Eli decided to move back to San Francisco. By 1888 Eli was in San Francisco with his daughter, Aminade and his niece, Dorothy. Marie Louise would join him a couple years later. In 1905, Eli Lequime's homestead was added to the K.L.O. company for $12,000.00.

 Passage 3:American expanded its service to Asia and the Pacific. It was one of the initial US bidders in February 2010 to serve Tokyo's Haneda Airport, and was awarded rights to serve Haneda from New York JFK. American planned to begin JFK-Haneda service in January 2011, but postponed the service until February 2011 citing low booking demand, ultimately terminating its JFK-Narita service in favor of JFK-Haneda service in June 2012. American later cancelled its JFK-Haneda service in October 2013 due to the service being "quite unprofitable" due to the time constraints at Haneda Airport. American also began service between Los Angeles and Shanghai in 2011 and between Dallas/Fort Worth and Seoul in 2013, and from Dallas/Fort Worth International Airport to both Shanghai and Hong Kong in the summer of 2014, providing the first ever nonstop service between Dallas/Fort Worth and China. In October 2014, American filed a report to the DOT to launch flights from Los Angeles to Tokyo-Haneda in place of Delta's Seattle-Tacoma operating slot, sparking a war that lasted for over eight months. American was originally granted the slot as a back-up to Delta's Seattle-Haneda route if it failed to operate on a daily basis on March 28, 2015 (which would give the operating rights to American), but in June 2015, Delta announced the cancellation of its Seattle-Haneda service, claiming the daily operation was not feasible due to the route not being an economically viable one in the Seattle market due to certain regulatory and market conditions. American launched daily service from Los Angeles to Tokyo-Haneda on February 11, 2016 using their Boeing 787 aircraft. American also added daily service from Los Angeles to Sydney, Auckland and Hong Kong on their flagship Boeing 777-300ER (to Sydney and Hong Kong) and Boeing 787-8 (to Auckland) respectively (the flights to Auckland and Sydney was replaced by Boeing 787-9 aircraft in Fall 2017), returning to Australia and New Zealand for the first time since the 1990s and providing the first ever non-stop service between the Continental U.S. and Australia and New Zealand on American Airlines. American added service from Los Angeles to Beijing on November 5, 2017, and has plans for more expansion in the Asia-Pacific region in the coming years. As of November 2017, American Airlines offers service to eight destinations in Asia and Oceania from its hubs in Los Angeles, Chicago and Dallas-Fort Worth, offering a total of fifteen routes.
