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: Which Mesopotamian civilization's city has the most people at its peak? Passage 1:He had hoped to redshirt during the 2011 season, which was his freshman year, so that he could add size. He played in 2011 as a true freshman and got off to a modest start. Lockett only recorded four receptions for 50 yards, three rushes for nine yards, one kickoff return for ten yards, and two punt returns for a total of 13 yards in his first five games through October 8. Things started to turn around on October 15 when he posted a 100-yard return of a kickoff for a touchdown against Texas Tech. Over the ensuing weeks, he earned numerous Big 12 Conference honors for the 2011 team, including becoming a two-time Big 12 Special Teams Player of the Week. His first Player of the Week recognition came on October 24 after he produced a 251-yard all-purpose yards performance on October 22 against Kansas in the Governor's Cup that included posting a 97-yard kickoff return touchdown while becoming the first player in school history to return kickoffs for touchdowns in consecutive games and having a career-high five-reception 110-yard receiving day. His other Player of the Week recognition that season came on November 7 after a 315-yard all-purpose yard November 5 game against Oklahoma State that included an 80-yard kickoff return and three rushes for 84 yards as well as three receptions for 32 yards and a touchdown. Due to what was at first an undisclosed injury, he did not play in the final three games of Kansas State's regular season. Later, the injury was determined to be a lacerated kidney. In the four games before the injury, he had at least three receptions and 125 all-purpose yards in each game.

These include First Prize at the 1940 American Negro Exposition in Chicago, induction into the Salón de la Plástica Mexicana in 1956, the Distinguished Alumni Award from the University of Iowa in 1996, a 1998 50-year traveling retrospective of her work sponsored by the Newberger Museum of Art at Purchase College, a NAACP Image Award in 2009, and a joint tribute after her death held by the Salón de la Plástica Mexicana and the Instituto Politécnico Nacional in 2013. Others include an award from the Women's Caucus for Art, the Art Institute of Chicago Legends and Legacy Award, Elizabeth Catlett Week in Berkeley, Elizabeth Catlett Day in Cleveland, honorary citizenship of New Orleans, honorary doctorates from Pace University and Carnegie Mellon, and the International Sculpture Center's Lifetime Achievement Award in contemporary sculpture. The Taller de Gráfica Popular won an international peace prize in part because of her achievements . She received a Candace Award from the National Coalition of 100 Black Women in 1991.
 Passage 3:A vast number of artifacts have been discovered from ancient Mesopotamia depicting explicit heterosexual sex. Glyptic art from the Sumerian Early Dynastic Period frequently shows scenes of frontal sex in the missionary position. In Mesopotamian votive plagues from the early second millennium BC, the man is usually shown entering the woman from behind while she bends over, drinking beer through a straw. Middle Assyrian lead votive figurines often represent the man standing and penetrating the woman as she rests on top of an altar. Scholars have traditionally interpreted all these depictions as scenes of ritual sex, but they are more likely to be associated with the cult of Inanna, the goddess of sex and prostitution. Many sexually explicit images were found in the temple of Inanna at Assur, which also contained models of male and female sexual organs, including stone phalli, which may have been worn around the neck as an amulet or used to decorate cult statues, and clay models of the female vulva.
