Definition: 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.
Input: Question: How old is the station that televised the 69th Academy Awards? 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:The 69th Academy Awards ceremony, organized by the Academy of Motion Picture Arts and Sciences (AMPAS) took place on March 24, 1997, at the Shrine Auditorium in Los Angeles beginning at 6:00 p.m. PST / 9:00 p.m. EST. During the ceremony, AMPAS presented the Academy Awards (commonly referred to as Oscars) in 24 categories honoring films released in 1996. The ceremony, televised in the United States by ABC, was produced by Gil Cates, and directed by Louis J. Horvitz. Actor Billy Crystal hosted the show for the fifth time. He first presided over the 62nd ceremony held in 1990 and had last hosted the 65th ceremony held in 1993. Three weeks earlier, in a ceremony held at the Regent Beverly Wilshire Hotel in Beverly Hills, California, on March 1, the Academy Awards for Technical Achievement were presented by host Helen Hunt. This also served as the launch event for DVD, with its U.S. launch being on the same day as the ceremony.
 Passage 3: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.
