He carried out doctoral study at the University of Oxford, followed by five years (19801985) teaching British civilisation at the Universite de Paris III, while pursuing studies in medieval thought (focusing on Peter Abelard) in connection with Jean Jolivet, at the Ecole pratique des hautes etudes en sciences religieuses. This was followed by two years as a Leverhulme research fellow at the University of Sheffield on editing the writings of Peter Abelard. Mews took up a position at Monash University as Lecturer in the Department of History in July 1987. He became involved in developing the Centre for Studies in Religion and Theology and in promoting studies in religion more generally, with a strong interest in interfaith work. He has had spells of study at the Institute for Advanced Study, Princeton, in 1990 and 2000, and has also again taught in Paris, at the Ecole pratique des hautes etudes (Ve section) and in the Ecole des hautes etudes en sciences sociales.
Passage 2:The interior of French Guiana was virtually unknown and Crevaux decided to lead an exploration into its depths. On July 8, 1877 Crevaux traveled up the Maroni River where he encountered the Galibi and the Bonis. He left the Maroni to follow a tributary, the Itany River, along the way he visited the Roucouyenne and then followed an Emerillon trail over the spine of the Tumuk Humak Mountains. He descended the other side of the mountains to the Jari River, a tributary of the Amazon. By December 1877 he had reached the Brazilian city of Belem. He was nearly naked and had lost or used most of his possessions, and was believed by the Brazilian inhabitants to be an escaped French prisoner and was refused any help. He was eventually aided by a fellow Frenchman who bought him passage on a ship back to France. Upon returning to France, Crevaux gave an account of his journey to the Societe de Geographie and was made a "Knight" of the Legion d'honneur.

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 201718 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 rebellion that Un'yo was dispatched in last? Passage 1:Cecil's success in 2011 was partly due to his training of the Khalid Abdullah-owned Frankel. In the 2010 season Frankel won the Royal Lodge Stakes and Group One Dewhurst Stakes. The following year he continued unbeaten, winning the Greenham Stakes, the 2,000 Guineas, the St. James's Palace Stakes at Royal Ascot, the Sussex Stakes and the Queen Elizabeth II Stakes. His six length victory in the 2,000 Guineas was described as "one of the greatest displays on a British racecourse". After his win in the Sussex Stakes Cecil himself described Frankel as "the best horse I've ever seen". Timeform and the International Federation of Horseracing Authorities rated him the best horse in the world. In his four-year-old season Frankel won the Group One Lockinge Stakes at Newbury before an eleven length victory in the Queen Anne Stakes at Royal Ascot, described in one national newspaper as "possibly the best single performance by any horse, on any track, since three Arabian stallions were imported into Britain to found the thoroughbred breed in the early years of the 18th century". Timeform raised their rating to 147, making Frankel the highest rated horse in their history. He won a second Sussex Stakes, at odds of 120, and then stepped up in distance to win by seven lengths the Juddmonte International Stakes at York over 10 furlongs. In October 2012 Frankel won the Champion Stakes at Ascot to finish his career unbeaten. "He's the best I've ever had, the best I've ever seen", Cecil told the BBC after the race, "I'd be very surprised if there's ever been a better."

Mrs. Williams served on the Board of Trustees for the Theodore Roosevelt Association where she received the Rose Award in 2004 for her many years of service and dedication to the organization. Williams was also recognised for her work in behalf of conservation and promoting a healthier environment by reducing pollution.
Passage 3:Un'yo was one of the ships dispatched to Kyushu in 1874 during the Saga Rebellion. In May 1875, she carried diplomats to Busan in Korea in an attempt by the Japanese government to open diplomatic relations with the Joseon dynasty government. After they were rebuffed in these negotiations, the Japanese government again dispatched Un'yo in September 1875 under the command of Inoue Yoshika to provoke a military response, in what was later termed the Ganghwa Island incident. This eventually led to the Treaty of Ganghwa, which opened the Korean Peninsula to Japanese trade. In 1876, Un'yo was assigned to assist in the suppression of the Hagi Rebellion, another uprising of disaffected former samurai. Un'yo was severely damaged when she ran aground off the coast of the Kii Peninsula, and was scrapped the following year.
