Given the task definition, example input & output, solve the new input case.
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: 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.

The question refers to the 704th unit and task about war which is decribed by Passage 1.

New input case for you: Question: When was the school at which Brillouin studied physics founded? Passage 1:From 1908 to 1912, Brillouin studied physics at the École Normale Supérieure, in Paris. From 1911 he studied under Jean Perrin until he left for the Ludwig Maximilian University of Munich (LMU), in 1912. At LMU, he studied theoretical physics with Arnold Sommerfeld. Just a few months before Brillouin's arrival at LMU, Max von Laue had conducted his experiment showing X-ray diffraction in a crystal lattice. In 1913, he went back to France to study at the University of Paris and it was in this year that Niels Bohr submitted his first paper on the Bohr model of the hydrogen atom. From 1914 until 1919, during World War I, he served in the military, developing the valve amplifier with G. A. Beauvais. At the conclusion of the war, he returned to the University of Paris to continue his studies with Paul Langevin, and was awarded his Docteur ès science in 1920. Brillouin's thesis jury was composed of Langevin, Marie Curie, and Jean Perrin and his thesis topic was on the quantum theory of solids. In his thesis, he proposed an equation of state based on the atomic vibrations (phonons) that propagate through it. He also studied the propagation of monochromatic light waves and their interaction with acoustic waves, i.e., scattering of light with a frequency change, which became known as Brillouin scattering.
 Passage 2:Indian Supercomputer design experience started first with C-DOT's CHIPPS - C-DOT High Performance Parallel Processing System. It was designed to work with a maximum of 192 nodes and later the Technology, Architecture, Design, and the Product's Hardware, Software, and Firmware were transferred to a similarly formed autonomous organization in Pune which was then called 'C-DACT' in the first place to refer to 'Centre for Development of Advanced Computing Technology' as it was intended originally to sound synonymous with C-DOT, but it was later renamed to C-DAC with 5 characters similar to that of C-DOT. CHIPPS was the base platform of the Indian Supercomputer Revolution initiated in 1988 and pursued more vigorously during the start of the 1991. Then, 'CHIPPS' which used Inmos T800 Transputer Architecture and Design in a massively parallel processing structure was augmented and was renamed to call it 'PARAM' by the policy makers of C-DAC though the original architects and the original designers of C-DOT opposed to the renaming process because 'PARAM' refers to GOD in Indian Root Language TAMIL and its ancient versions including Sanskrit. Indian Supercomputer 'PARAM 8000' named by the Centre for Development of Advanced Computing (C-DAC), headed by Dr. Vijay Pandurang Bhatkar, was launched on July 1, 1991. It was released in 1991 by C-DAC and was replicated and installed at ICAD Moscow in 1991 under Russian collaboration.
 Passage 3:When Squires became a professional singer she performed with big bands such as Ted Heath, Geraldo and Cyril Stapleton. She also sang with the smaller jazz bands of Max Harris, Kenny Baker and appeared in the BBC Festival of Jazz at the Royal Albert Hall with the Alan Clare band. She moved from Salisbury to London in 1948 at 20 years of age. In the 1950s and 60s she became a regular on the BBC Light Programme (now BBC Radio 2) on programmes like Melody Time and Workers' Playtime. Squires worked in the United States with Danny Kaye and Sammy Davis Jr., as well as appearing on the Johnny Carson Show. In 1994 Squires was part of the entertainment for Prince Edward's 30th birthday celebrations. During the 2012 Royal Diamond Jubilee year Squires undertook two countrywide tours to celebrate her own diamond jubilee in show business including two appearances at the Royal Festival Hall.
