Detailed Instructions: 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.
See one example below:
Problem: 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.

Problem: Question: How many league championships has the team won that Maamria began his playing career with? Passage 1:Alben's research focuses on problems arising in biomechanics and material science. As a graduate student at NYU, Alben worked with Jun Zhang and Michael Shelley in investigating the dynamics of flexible structures and how such structures can become more aerodynamic by altering their shape. In this study, experiments visualized a short glass fiber deforming in fluid flow, and analysis showed how the fiber can reduce the drag force exerted by the fluid by changing its shape. This work was published 2002 in Nature under the title Drag Reduction Through Self-Similar Bending of a Flexible Body, and was the subject of various news articles in periodicals including The New York Times and others. As a Postdoctoral Fellow at Harvard, Alben collaborated with Ernst A. van Nierop and Michael P. Brenner in a paper titled "How Bumps on Whale Flippers Delay Stall: An Aerodynamic Model". The paper gave a mathematical model for this hydrodynamic phenomenon. This result, featured in MIT's Technology Review and Nature, provides a theoretical basis for potential improvements in using bumps for more stable airplanes, more agile submarines, and more efficient turbine blades. In 2007, Alben investigated (with Michael P. Brenner) the self-assembly of a 3D structures from flat, elastic sheets. This experiment, featured on New Scientist, presented a new technique in nano construction; previously, the transformation of flat sheets to 3D structures were performed by random formation, but in this study, the addition of biases into the design of the sheets gave the possibility of predicting the resulting shape.
 Passage 2:De Biasi, a midfielder, started his professional playing career for Inter Milan; he was part of the first team squad but, despite this, never played for the nerazzurri and was then loaned to Serie C team Reggiana in 1975 and newly promoted Serie A club Pescara Calcio one year later. He was sold to Brescia in 1977 as partial compensation for the signing of Evaristo Beccalossi by Inter. De Biasi played in Brescia for five seasons, only one of them in Serie A. He then moved to Palermo in 1983, but abruptly left it three years later following the cancellation of the Sicilian club in the summer of 1986. This was followed by a single season with Vicenza and two Serie C2 seasons for Treviso. De Biasi retired from active football in 1990, after a Serie D season with Bassano.
 Passage 3:Maamria started his playing career with AS Marsa of Tunisia. He left the club in 1994, and spent a season at CO Transports. He moved to England in 1996, and joined Burnley. Maamria subsequently signed for Glentoran of the IFA Premiership, spending the remainder of 1996–97 season with the club. He joined Conference National side Doncaster Rovers in 1998, spending two years at the club. He spent the 2000–01 season at Southport, before signing for Leigh RMI in July 2001. After two successful seasons at Leigh, Maamria signed for Stevenage Borough for a five-figure fee in February 2003. He left the club after making just ten appearances, joining Charleston Battery of the USL First Division. He made nine appearances for Charleston, before rejoining Stevenage in September 2003. Maamria went on to spend three seasons with Stevenage. In July 2006, he rejoined Southport, before signing for Rushden & Diamonds on a free transfer in January 2007. After being released by Rushden at the end of the 2006–07 season, Maamria signed for Northwich Victoria in August 2007.
