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 input: 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.

Q: Question: Of the two actors announced in late August 2017, who has appeared in the most credited roles in film and television? Passage 1:Southern Utah has the densest population of slot canyons in the world with over one thousand slot canyons in the desert lands south of Interstate 70. Utah's slot canyons are found in Zion National Park at The Narrows, along Canyonlands National Park's Joint Trail, throughout Capitol Reef National Park, within the San Rafael Swell and the Grand Staircase-Escalante National Monument, especially along the Escalante River drainage including Coyote Gulch. Many more slot canyons are located on public Bureau of Land Management and state-owned lands in southern Utah, in areas surrounding the aforementioned parks and monuments. Buckskin Gulch—one of the longest slot canyons in the world—begins in southern Utah and continues into northern Arizona within the Paria Canyon-Vermilion Cliffs Wilderness. Northern Arizona also has a high concentration of slot canyons including Antelope Canyon and Secret Canyon, which are two of the most famous slot canyons located near Page on land owned by the Navajo Nation. Slot canyons are also located in the valley between U.S. Route 89 and the Vermilion Cliffs in Arizona, and can be seen as one descends into the valley on U.S. 89, but these are on the Navajo reservation and are closed to the public. The Kasha-Katuwe Tent Rocks National Monument's slot canyon trail in New Mexico is unique as it was carved into tuff (volcanic ash). In California, several slot canyons are located within Death Valley National Park.
 Passage 2:On March 8, 2017, it was announced that 20th Century Fox had bought the spec script Bad Times at the El Royale, written by Drew Goddard, who would also direct and produce the film. On August 23, 2017, Chris Hemsworth and Jeff Bridges were cast in the 1960s-set film, to play two among the several characters who collide at the El Royale hotel, near California's Lake Tahoe. That same day, it was also reported that Tom Holland had passed on a role, and that Beyoncé was being courted for the role of a Black vocalist. It was also revealed that main roles in the ensemble would include a vacuum cleaner salesman, two female criminals, a male cult leader, and a desk clerk. Later in August 2017, newcomer Cailee Spaeny was added to the cast to play an impressionable Southern girl brought to the hotel, while Cynthia Erivo was cast as the Black singer who finds herself in the wrong place at the wrong time. In January 2018, Dakota Johnson and Russell Crowe joined the cast (though Crowe did not appear in the film). In February 2018, Jon Hamm, Nick Offerman, and Mark O'Brien joined the cast, and in May 2018, Lewis Pullman was also confirmed for a role.
 Passage 3:The film was only a modest hit when first released. O'Connor won the Golden Globe Award for Best Actor – Motion Picture Musical or Comedy, and Betty Comden and Adolph Green won the Writers Guild of America Award for their screenplay, while Jean Hagen was nominated for the Academy Award for Best Supporting Actress. However, it has since been accorded legendary status by contemporary critics, and is frequently regarded as the best film musical ever made, and the best film ever made in the "Freed Unit" at Metro-Goldwyn-Mayer. It topped the AFI's Greatest Movie Musicals list and is ranked as the fifth-greatest American motion picture of all time in its updated list of the greatest American films in 2007. In 1989, the United States Library of Congress selected the film for preservation in the National Film Registry. In 2005 the British Film Institute included it in its list of the 50 films to be seen by the age of 14. In Sight & Sound magazine's 2017 list of the 50 greatest films of all time, Singin' in the Rain placed 20th.
