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.
One 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.

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

Now, solve this: Question: How long is the river that the two bodies were transported on? Passage 1:Paul of Tammah departed on 7 Paopi (October 17, 415 AD). He was buried along with Saint Pishoy in the Monastery of Saint Pishoy at Deir El Barsha, which still exists today near Mallawi. On 4 Koiak 557 AM (December 13, 841 AD), Pope Joseph I fulfilled the desire of Saint Pishoy and moved his body as well as that of Saint Paul of Tammah to the Monastery of Saint Pishoy in the wilderness of Scetes. It is said that they first attempted to move the body of Saint Pishoy only, but when they carried it to the boat on the Nile, the boat would not move until they brought in the body of Saint Paul of Tammah as well. Today, the two bodies lie in the main church of the Coptic Orthodox Monastery of Saint Pishoy in the Nitrian Desert.
 Passage 2:For the Republicans, businessman and candidate for the U.S. Senate in 2014 Matt Bevin ran on a ticket with Tea Party activist and 2014 State House candidate Jenean Hampton; Agriculture Commissioner of Kentucky James Comer ran on a ticket with State Senator Christian McDaniel; former Louisville Metro Councilman and nominee for Mayor of Louisville in 2010 Hal Heiner ran on a ticket with former Lexington-Fayette Urban County Councilwoman and nominee for Kentucky State Treasurer in 2011 K.C. Crosbie; and former Associate Justice of the Kentucky Supreme Court Will T. Scott ran on a ticket with former Menifee County Sheriff Rodney Coffey. Bevin held an 83-vote lead over Comer in the primary election, with both Heiner and Scott conceding. The Associated Press, referring to the race between Bevin and Comer a "virtual tie", did not called the race in favor of either candidate. In addition, Comer refused to concede and stated that he would ask for a recanvass. The request for recanvass was filed with the Kentucky Secretary of State's office on May 20, 2015 with Secretary of State Alison Lundergan Grimes ordering the recanvass to occur at 9:00 a.m. local time on Thursday, May 28, 2015. Upon completion of the recanvass, Grimes announced that Bevin remained 83 votes ahead of Comer. Grimes also stated that should Comer want a full recount, it would require a court order from the Franklin Circuit Court. On May 29, Comer announced he would not request a recount and conceded the nomination to Bevin.
 Passage 3:During the expedition, Father Crespí observed a location along the river that would be good for a settlement or mission. However, in 1771, Father Serra instead commissioned two missionaries to establish the Mission San Gabriel Arcángel-San Gabriel Mission near the present day Whittier Narrows section of the San Gabriel River. The missionaries encountered resistance from the Tongva to their attempts to resettle the Natives on the mission. The mission encountered further trouble in 1776 when a flood damaged the mission, convincing the missionaries to move and rebuild the mission on a higher and more defensible location: its present site in San Gabriel. The first Spanish governor of Las Californias, Felipe de Neve had, as well, recommended to Viceroy Bucareli Father Crespí's location on the Río Porciúncula (Los Angeles River) for a mission. Instead, in 1781, King Charles III mandated that a pueblo be built on the site instead, which would be the second town in Alta California, after San José de Guadalupe in 1777. The monarch, disregarding the production and trade roles of the missions, saw a greater need for secular pueblos to be established as the centers of agriculture and commerce to supply the crown's ever-growing military presence in "Nueva California." The priests at the missions ignored the royal mandate and continued their ranching, trading and production of tallow, soap, hides, and beef, often in competition with new pueblo ventures.
