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.

Example explanation: The question refers to the 704th unit and task about war which is decribed by Passage 1.
Q: Question: Youchi Akasaka and Tadashi Nishimura worked at company that is headquartered where? Passage 1:Although Scream of the Shalka continues the narrative of the original 1963–89 programme and the 1996 television film, the show's 2005 revival ignored its events. The series was scripted by veteran Doctor Who writer Paul Cornell, with Richard E. Grant providing the voice for the Ninth Doctor. This performance followed years of rumours that Grant would play the Doctor in a film or new series, and indeed he had appeared as the "Conceited Doctor" in the Comic Relief special Doctor Who and the Curse of Fatal Death in 1999. Grant subsequently went on to appear in the revived television series of Doctor Who as a guest villain in 2012's "The Snowmen" and 2013's "The Bells of Saint John" and "The Name of the Doctor". The Doctor's companion for this adventure, Alison Cheney, was voiced by Sophie Okonedo who a year later would be nominated for an Academy Award for her performance in Hotel Rwanda. She also appeared in the 2010 series of Doctor Who, as Liz 10, in the episodes "The Beast Below" and "The Pandorica Opens". Derek Jacobi reprised his role as the Master in 2007's "Utopia". David Tennant appeared in a cameo role as the Caretaker, later being cast as the Tenth Doctor in 2005.
 Passage 2:In 1986, Mitsubishi Electric researchers Yoichi Akasaka and Tadashi Nishimura laid out the basic concepts and proposed technologies for 3D ICs. The following year, a Mitsubishi research team including Nishimura, Akasaka and Osaka University graduate Yasuo Inoue fabricated an image signal processor (ISP) on a 3D IC, with an array of photosensors, CMOS A-to-D converters, arithmetic logic units (ALU) and shift registers arranged in a three-layer structure. In 1989, an NEC research team led by Yoshihiro Hayashi fabricated a 3D IC with a four-layer structure using laser beam crystallisation. In 1990, a Matsushita research team including K. Yamazaki, Y. Itoh and A. Wada fabricated a parallel image signal processor on a four-layer 3D IC, with SOI (silicon-on-insulator) layers formed by laser recrystallization, and the four layers consisting of an optical sensor, level detector, memory and ALU.
 Passage 3:Primarily a midfielder, Jüllich began his career with Waldhof Mannheim, where he played for two seasons in the Regionalliga before joining Bayern in July 2010. He made his 3. Liga debut in the opening match of the 2010–11 season, a 1–0 defeat against SV Babelsberg. He has played for Bayern's first-team in pre-season friendlies in 2010, most notably the Franz Beckenbauer farewell match against Real Madrid, where he played as a stand-in for Philipp Lahm at right back, and earned praise for his performance up against Cristiano Ronaldo. He was named in Bayern's squad for the 2010–11 UEFA Champions League, where he was given the number 34, and was named on the substitutes' bench for a Bundesliga match against Hannover 96 in October 2010. After two years with Bayern's reserves, he joined 1. FC Saarbrücken in summer 2012, where he spent a season before being released in 2013. He signed for SG Sonnenhof Großaspach four months later.
