Example Input: 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 Pathé and Disney (Santa's Workshop) and the main film—The 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 Méphistophélès 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'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.

Example Input: Question: Comparing the city in which Ptacek was born with the US city to which his family settled in, which city is larger in size? Passage 1:Secretary of State for Employment and Productivity Barbara Castle introduced an Employed Persons (Health and Safety) Bill in 1970 but the debate around the Bill soon generated a belief that it did not address fundamental issues of workplace safety. In the same year, the Occupational Safety and Health Act was passed into United States federal law. As a result, a committee of inquiry chaired by Lord Robens was established towards the end of Harold Wilson's first government. When the Conservative Party came to power following the 1970 United Kingdom general election, they gave Castle's Bill no parliamentary time, preferring to wait for the Robens Report which was published in 1972. Conservative Secretary of State for Employment William Whitelaw introduced a new Bill on 28 January 1974 but Labour were returned to power in the February 1974 United Kingdom general election and the Bill again lost. The new Labour administration finally secured the passage of a Bill that year.
 Passage 2:June started with striker Mark Stewart having the second year of his contract cancelled. Following this Turnberry Homes signed a new two-year deal to continue as the club's shirt sponsors. Bobby Barr became the club's second signing of the summer, joining on a year long deal from Raith Rovers. Ross Forbes was announced as the club's third summer signing on 11 June - signing a season long deal nine years after a loan spell with the club. A day later the club's top scorer from the 2017–18 season, Calum Gallagher, signed a new one-year deal. The week ended with Grant Adam becoming the club's fourth signing of the summer, joining on a one year deal from Forfar Athletic. His arrival was followed by that of striker Rory Loy, who joined after leaving Falkirk, however Danny Handling turned down a new deal with the club to join Scottish League Two side Edinburgh City. Stuart Carswell was the next player to commit himself for another season, signing a new one-year deal after 54 appearances and two goals in his 18 months at the club. The following week defenders Ross Perry and Cammy Ballantyne signed for the club on year-long deals, and they were joined by Ryan Thomson who joined after leaving Stranraer. A day after signing Thomson marked his debut with a goal, which was added to by strikes from Calum Gallagher and Iain Russell (playing as a trialist) as Dumbarton overcame Lowland League side East Kilbride in their first friendly of the season.
 Passage 3:Ptacek was born in East Berlin to a family of Czech and German descent. His family fled East Germany for the United States when he was five years old. They eventually settled in Chicago, where young Ptacek was first exposed to blues music. He moved to Tucson in the early 1970s, where he began his own musical career, most often solo, but sometimes he plugged in and led a trio as Rainer & Das Combo. He co-founded Giant Sandworms with Howe Gelb in the late 1970s. When the band decided to move to New York and became Giant Sand, Ptacek opted to stay in Tucson to make sure that he would not disrupt his then-new family. Although he never became well known in the United States, he became more and more recognized in Europe. ZZ Top guitarist Billy Gibbons was so impressed with the singer-guitarist that he arranged to have Kurt Loder review Ptacek's "Mush Mind Blues" cassette in Rolling Stone. Ptacek later traveled to Houston at the invitation of Billy Gibbons to record at Gibbons' Gold Star Sound Services studio which saw release as "The Texas Tapes" meeting international attention and approval. Robert Plant, similarly impressed, flew Ptacek to England for the sessions for B-sides to supplement the singles from Fate of Nations.

Example Input: Question: How long did the Minister of Public Safety at the time serve in that role? Passage 1:Georges Sada was born in 1939 in Iraq into a Christian family of Assyrian ethnicity (see his account). As a boy, Sada attended the Assyrian Church of the East with his family, later becoming a 'born-again' Christian and attending a more evangelical church. Throughout his childhood, Sada had a keen interest in military aircraft and the Air Force, playing as a boy at the RAF Base where his father was stationed, and imagining himself flying the fighters he saw taking off. In this time he did 'odd jobs' at the base, befriending both the pilots and the technicians who repaired their aircraft, resolving that one day he himself would have a career in the Air Force as a pilot. In 1958 at the age of nineteen, Sada applied to the air academy in Iraq and was accepted as a cadet, graduating from the Iraqi Air Academy in 1959. Over the following years he served as an Air Force Officer, including periods studying overseas in Britain, the USSR and the United States. Between 1964–1965 he was a student at Lackland Air Force Base in Texas. Sada's career in the air force spanned 28 years, from 1958 to 1986. He officially retired in 1986 as a two-star officer, but was later called back to active service as an Air Vice Marshal for the 1990 invasion of Kuwait. During the conflict Sada defied the orders of Saddam Hussein by refusing to execute POWs, attributing this disobedience to his strong Christian convictions. In interviews, Sada has described his attempts to persuade Saddam not to harm the prisoners (an action which would have violated the Geneva Convention and would have been a war crime): Saddam eventually relented and spared the POWs, although Sada himself was subsequently imprisoned for a time. In his book Saddam's Secrets, Sada states that Saddam did not want him harmed after his release, but wanted no further contact with him thereafter.
 Passage 2:Ali was one of several men hired by the United States Army to introduce camels as beasts of burden to transport cargo across the "Great American Desert." Eight of the men – including Ali – were of Greek origin. They arrived at the Port of Indianola in Calhoun County, Texas on the . The book Go West Greek George by Steven Dean Pastis, published in both Greek and English, specifically identifies all eight men. These pioneers were Yiorgos Caralambo (later known as Greek George), Hadji Ali (Hi Jolly, a.k.a. Philip Tedro), Mimico Teodora (Mico), Hadjiatis Yannaco (Long Tom), Anastasio Coralli (Short Tom), Michelo Georgios, Yanni Iliato, and Giorgios Costi. The Americans acquired three camels in Tunis, nine in Egypt and 21 in Smyrna: 33 in all. Ali was the lead camel driver during the US Army's experiment with the U.S. Camel Corps in using camels in the dry deserts of the Southwest. After successfully traveling round trip from Texas to California, the experiment failed, partly due to the problem that the Army's burros, horses, and mules feared the large animals, often panicking, and the tensions of the American Civil War led to Congress not approving more funds for the Corps. In 1864, the camels were finally auctioned off in Benicia, California, and Camp Verde, Texas. Ali was discharged from the Quartermaster Department of the U.S. Army at Fort McDowell in 1870.
 Passage 3:The Adult Entertainment Association of Canada (abbreviated AEAC, also called the Adult Association of Canada) is a coalition of strip club owners and their agents that represents 53 of the 140 strip clubs in Ontario, Canada. Tim Lambrinos is the organization's director. The Exotic Dancers' Alliance (EDA), a collective that was founded in 1995 to bring together both former and current strippers and their supporters, sought to establish minimum employment standards for strippers in Ontario by contending with the AEAC, but the EDA ceased to exist in 2004. Also in 2004, Ottawa instituted a law against lap dancing, and the AEAC unsuccessfully attempted to have the law overturned in 2007. Starting in 2004, the AEAC and the Department of Citizenship and Immigration Canada became embroiled in a long-standing controversy about work permits for foreign workers to be hired for the purpose of striptease. In 2008, when Minister of Citizenship and Immigration Diane Finley allegedly received threats from sex industry officials in relation to her support of Bill C-17, which sought to allow immigration officers to deny temporary visas to prospective strippers if they were suspected to be sex trafficking victims, Lambrinos said that "it's not plausible" that any of the AEAC strip clubs were responsible for the threats. In 2009, the AEAC invited Toronto City Council members to attend a free lunch at a strip club in the city, and three councillors accepted the invitation. The AEAC released a statement in 2010 that the government's crackdown on sex industry worker visas had resulted in a stripper shortage, and Minister of Public Safety Vic Toews responded by saying that the strip clubs that were short on strippers because of the crackdown were engaging in human trafficking. Toews then ordered the Royal Canadian Mounted Police to investigate the relevant strip clubs in order to determine whether or not the strippers working there were illegal immigrants or sex trafficking victims, and the AEAC launched a campaign to deny these allegations.
