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.
Input: Question: Between the two Beethoven pieces Ezio has performed, which one is longer? 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 Pathé and Disney (Santa's Workshop) and the main film—The Private Life of Henry VIII starring Charles Laughton.
 Passage 2:Varignon was a friend of Newton, Leibniz, and the Bernoulli family. Varignon's principal contributions were to graphic statics and mechanics. Except for l'Hôpital, 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 mécanique 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.
 Passage 3: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 Méphistophélès in Guonod's Faust opposite his daughter, soprano Claudia Pinza Bozzolla, as Marguerite at the San Francisco Opera.
