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: Which of the works produced by Greg in 1923 was longer? Passage 1:The Los Angeles Rams are a professional American football team that plays and competes in the National Football League (NFL). The Rams franchise was founded in 1936 as the Cleveland Rams in the short-lived second American Football League before joining the NFL the next year. In 1946, the franchise moved to Los Angeles. The Rams franchise remained in the metro area until 1994, when they moved to St. Louis, and were known as the St. Louis Rams from 1995 to 2015. The Rams franchise returned to Los Angeles in 2016. This article chronicles the franchise's history during their time in Los Angeles, from playing at the Los Angeles Memorial Coliseum between 1946 and 1979, to playing at Anaheim Stadium (now known as Angel Stadium of Anaheim) in Anaheim from 1980 to 1994, and its return to Southern California beginning with the season playing temporarily at their old home the Los Angeles Memorial Coliseum before moving to SoFi Stadium in Inglewood in 2020 alongside the Los Angeles Chargers.
 Passage 2:The station is situated at the northern end of the relatively straight Duisburg to Düsseldorf railway line which has to cope with one of the highest daily loads in continental Europe. This line is slated to be widened to six tracks in the near future. Currently it has four—and in some places five—tracks. Parallel to it to the east is the local line to Duisburg-Wedau, remnant of a relief line to Düsseldorf which only sees a local shuttle service today but is heavily used by freight trains (which usually do not run through the station but bypass it on a freight-only line two miles to the east). The third line from the south is the railway line to Krefeld and Mönchengladbach. This crosses the River Rhine and then splits into the main line and a branch to Moers and Xanten at Rheinhausen. North of the station, seven tracks run to the River Ruhr crossing (which is a sight on the Route der Industriekultur (Route of industrial heritage) due to a maze of girder bridges) where a three track line split for Oberhausen and on to Antwerp and the other line runs to Dortmund via Gelsenkirchen. The four-tracked main line turns east and runs via Essen and Bochum to Dortmund.
 Passage 3:After school, Greg settled into a life of steady productivity, while living on the proceeds of his shares of The Economist. Working in close association with A. H. Bullen, he produced Pastoral Poetry and Pastoral Drama (1906), the first edited version of the account books of Philip Henslowe (1906–8) and the papers of Edward Alleyn. The latter two works provided him with a knowledge of Renaissance theatrical conditions perhaps rivaled only by E. K. Chambers, and this knowledge he applied to the publications of the Malone Society, which he served as general editor between 1906 and 1939. He served as Librarian of Trinity College, 1907–13, resigning after his marriage to his cousin Elizabeth Gaskell. As an independent scholar, Greg produced editions of The Merry Wives of Windsor (1910), Robert Greene's Orlando Furioso and George Peele's The Battle of Alcazar (published together, 1923), and Sir Thomas More (1911). He returned to specific editing with work on Doctor Faustus (1950). Greg also wrote on the material conditions of Renaissance theater and publishing; his work in this regard includes Dramatic Documents from the Elizabethan Playhouses (1931) and English Literary Autographs, 1550–1650 (1932). The Variants in the First Quarto of King Lear (1940) offered a careful examination of this printing. He also wrote hundreds of reviews, including a notably caustic rejection of J. Churton Collins's 1905 Oxford edition of Robert Greene.
