[EX Q]: Question: Which of the orchestras that Ezio performed with in New York was established later? Passage 1:The Astoria chain was well established in London by the early 1930s. Cinemas and theatres of that name were built in Brixton (now the Brixton Academy), Finsbury Park, Charing Cross Road, Old Kent Road and Streatham. All were designed by Edward Albert Stone. The brand was soon extended to seaside resorts across southeast England at the initiative of a group of businessmen led by E.E. Lyons. ("Teddy" Lyons had opened one of Brighton's earliest cinemas, the Academy, in 1911 and was well known in the town's entertainment scene.) The group, which also included Sussex Daily News proprietor J.H. Infield (who served as chairman of the Academy Cinema until 1926), had identified a site in 1932 when they planned to open a cinema under the Plaza brand. This did not happen, but in 1933 the consortium commissioned Edward Stone to build a "super cinema" under the Astoria name there. The site was on Gloucester Place, north of Old Steine, and a number of houses from the Georgian and Victorian eras were knocked down to make way. Work began on 17 July 1933 on the 1,823-seat building, which was designed as a combined theatre and cinema with a full stage and dressing rooms. Thursday 21 December 1933 was the opening night; Cooper Rawson and Margaret Hardy, respectively Brighton's Member of Parliament and Mayor, made the inaugural speeches. These were followed by a Movietone News newsreel, features by Pathe and Disney (Santa's Workshop) and the main filmThe Private Life of Henry VIII starring Charles Laughton.
Passage 2:Pinza sang once again under the baton of Toscanini in 1935, this time with the New York Philharmonic Orchestra, as the bass soloist in performances of Beethoven's Missa Solemnis. One of these performances was broadcast by CBS and preserved on transcription discs; this recording has been issued on LPs and CDs. He also sang in Toscanini's February 6, 1938, NBC Symphony Orchestra's broadcast performance of Beethoven's Ninth Symphony. These performances both took place in Carnegie Hall. In March 1942, Pinza was arrested at his home and unjustly detained 3 months on Ellis Island with hundreds of other Italian-Americans who were suspected of supporting the Axis. The incident was extremely traumatic for Pinza, and he suffered from severe depression for years afterward. In October 1947, he performed the role of Mephistopheles in Guonod's Faust opposite his daughter, soprano Claudia Pinza Bozzolla, as Marguerite at the San Francisco Opera.
Passage 3:Varignon was a friend of Newton, Leibniz, and the Bernoulli family. Varignon's principal contributions were to graphic statics and mechanics. Except for l'Hopital, Varignon was the earliest and strongest French advocate of infinitesimal calculus, and exposed the errors in Michel Rolle's critique thereof. He recognized the importance of a test for the convergence of series, but analytical difficulties prevented his success. Nevertheless, he simplified the proofs of many propositions in mechanics, adapted Leibniz's calculus to the inertial mechanics of Newton's Principia, and treated mechanics in terms of the composition of forces in Projet d'une nouvelle mecanique in 1687. Among Varignon's other works was a 1699 publication concerning the application of differential calculus to fluid flow and to water clocks. In 1690 he created a mechanical explanation of gravitation. In 1702 he applied calculus to spring-driven clocks. In 1704, he invented the U-tube manometer, a device capable of measuring rarefaction in gases.

[EX Q]: Question: Which of the annual events that take place at Expo New Mexico gets more visitors? Passage 1:After Landau moved to the Kapitza institute in Moscow (to avoid arrest for comparing Stalinism to Nazism), Pomeranchuk also moved there, working for the tanning industry. He returned to Leningrad in 1938, lecturing, completing his Ph.D. and becoming employed as a junior scientist. He joined the Lebedev Institute of the Academy of Sciences of the USSR in Moscow as a senior scientist in 1940. In 1941 the institute was evacuated to Kazan. Under Abraham Alikhanov, he studied cosmic rays in Armenia from 1942. In 1943, he transferred to Laboratory No.2 under Igor Kurchatov as part of the Soviet project to develop nuclear weapons. Alikhanov founded Laboratory No.3 (which became the Institute for Theoretical and Experimental Physics (ITEP)) and Pomeranchuk worked there from 1946 (and for the rest of his life), founding and leading the Theoretical department, as well as being Professor of Theoretical Physics at the Moscow Mechanical Institute where students admired his infectious enthusiasm for his subject. Rudolf Peierls was consoled by the fact that it was "very clever Pomeranchuk" - and no-one else - who corrected his 1/T law for heat conduction in high-temperature condensed matter physics. His work in the 1940s was dominated by neutron research and his manuscript with Akhiezer was the basic guide for Soviet nuclear reactor construction. In 1950, he published a paper suggesting that the entropy of helium-3 as a liquid was less than as a solid. In 1950, Pomeranchuk received an order from Josef Stalin to go to Arzamas-16, located in the closed city of Sarov, Nizhny Novgorod region, to work on Soviet nuclear weaponry. Missing his family and his 'hobby physics' problems, he was advised not to apply for a revocation but wait until the order was "forgotten." He returned to ITEP within a year. He continued enthusiastically with work on quantum field theory and S-matrix theory, particle collisions and Regge theory, the latter in vigorous collaboration with Vladimir Gribov. His last paper on Regge theory was published posthumously. For his work, Pomeranchuk was twice awarded the Stalin Prize (1950, 1952). He was elected a corresponding member of the Academy of Sciences of the USSR in 1953 and full member in 1964.
Passage 2:The city is home of the International Balloon Fiesta, the world's largest gathering of hot-air balloons, taking place every October. The New Mexico State Fair and Gathering of Nations are held annually at Expo New Mexico, other major venues throughout the metropolitan area include the University of New Mexico's Popejoy Hall, Santa Ana Star Center, Isleta Amphitheater and historic theaters such as the KiMo Theater and El Rey Theater. Old Town Albuquerque hosts traditional fiestas and events such as weddings, and the Civic Plaza, with its Al Hurricane Pavillion and Albuquerque Convention Center, hosts a myriad of events including large concerts and conventions. Due to its population size, the metropolitan area regularly has New Mexico music concerts and receives most of New Mexico's national and international music concerts, Broadway shows, and other traveling events. Likewise, the city is home to a diverse restaurant scene from various global cuisines and the state's distinct New Mexican cuisine.
Passage 3:McCammon never played in the NHL, spending his entire career in the minor leagues. He was the head coach of the Maine Mariners of the American Hockey League and won the Calder Cup in 1977-78 and 197879, the first two years of the team's existence. McCammon had two stints as head coach of the Philadelphia Flyers, also serving as the team's general manager during the latter. He was also the head coach of the Vancouver Canucks and an assistant coach for the Edmonton Oilers on two different occasions. With Vancouver in 198889, he was runner-up to Pat Burns of the Montreal Canadiens for the Jack Adams Trophy as NHL Coach of the Year. He won the Stanley Cup with the Edmonton Oilers in 1987 as director of player development, and in 2002 and 2008 as a scout with Detroit. McCammon's name was added to the Stanley Cup in 2002 with Detroit.

[EX Q]: Question: When was the school at which Brillouin studied physics founded? Passage 1:From 1908 to 1912, Brillouin studied physics at the Ecole Normale Superieure, 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 es 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.
