He carried out doctoral study at the University of Oxford, followed by five years (1980–1985) 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 École pratique des hautes études en sciences religieuses.

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 École pratique des hautes études (Ve section) and in the École des hautes études 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 Belém. 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 Société de Géographie and was made a "Knight" of the Légion d'honneur.

Question: Which team won the tournament that Harvard was eliminated from by UNC in 2015? Passage 1:Bundrick first worked with Pete Townshend in 1977 when he performed on Rough Mix, Townshend's solo collaboration with Ronnie Lane, former bass player for Small Faces and Faces. He was invited to play on the Who's album Who Are You (1978), but broke his arm falling out of a taxi at the studio door and was unable to participate in recording sessions. Bundrick toured with The Who from 1979 to 1981 along with drummer Kenney Jones and played on their album Face Dances (1981), then briefly parted with the band during the recording of It's Hard (1982) and the subsequent tour. Bundrick later rejoined the band performing with them at Live Aid in 1985 and played live with them until 2012.
 Passage 2:The book discusses four prehistoric migrations in India. The book mentions that the Harappans were a mixture of Zagros agriculturists and First Indians, a wave of migrants who came from Africa into Arabia and then reached India around 65,000 years ago. Citing recent DNA evidence, the book traces the subsequent large migrations of anatomically modern humans into India—of agriculturalists from Iran between 7000 and 3000 BCE and Indo-European languages speaking pastoralists from the Central Asian Steppe (Aryans) between 2000 and 1000 BCE, among others. Tony Joseph used pizza as a metaphor to explain the break-up of subcontinental society. The book also discusses about similarities and differences between Indus Valley civilization and early Vedic civilization. The book mentions that ‘Aryan’ culture was most likely the result of interaction, adoption and adaptation among those who brought Indo-European languages to India and those who were already well-settled inhabitants of the region, and that Sanskrit and Vedas developed in the Indian subcontinent. Various tribes like the Andamanese and the Semang (Malay Peninsula), the Mani (Thailand) and the Aeta people (the Philippines) were the earliest inhabitants of Southeast Asia. According to Joseph, Proto-Dravidian is related to the Elamitic language of Iran. Caste system in India is a recent social system, reflected in sharply reduced inter-marriage (endogamy) and genetic mixing after 100 AD. This book also takes into account the path-breaking DNA research and findings from geneticist David Reich's research.
 Passage 3:Harvard Crimson men's basketball program represents intercollegiate men's basketball at Harvard University. The team currently competes in the Ivy League in Division I of the National Collegiate Athletic Association (NCAA) and plays home games at the Lavietes Pavilion in Boston, Massachusetts. The team appeared in the NCAA Division I Men's Basketball Tournament in 2014, where Harvard upset 5-seed Cincinnati 61–57 before being eliminated in the round of 32 by 4-seed Michigan State by a score of 80–73. In 2015, Harvard tied with Yale for the Ivy title with an 11–3 league record. Despite having lost to Yale 62–52 at Lavietes Pavilion on March 6, 2015, just eight days later Harvard won a playoff between the two at the Palestra in Philadelphia to determine the Ivy League's NCAA automatic bid by a score of 53–51. Harvard thereby achieved its fourth straight NCAA Tournament appearance while preventing Yale from reaching the NCAA Tournament for the first time in 53 years. Harvard was eliminated from the 2015 NCAA Tournament by UNC by a score of 67–65 after leading with under one minute to play in the game.

Question: Which of East 17's singles stayed in the top 10 for the least number of weeks? Passage 1:On 30 January 1969, Stribling put to sea from Mayport, Florida, to make her second voyage to the Far East. Heading via the Panama Canal, San Diego, and Pearl Harbor, the destroyer made for Yokosuka, Japan, and then operations off the coast of Vietnam. Stribling participated in "Sea Dragon" and "Market Time" operations, and her duties also included bombardments on the gunline, search and rescue missions usually for downed carrier pilots, and Positive Identification Radar Advisory Zone (PIRAZ) duty. The latter assignment involved riding "shotgun" for larger PIRAZ ships armed with more sophisticated radar and target designation systems. That summer, Stribling plane-guarded for the carriers operating on "Yankee Station" in the Gulf of Tonkin. When not operating in the combat zone, she put into Kaohsiung, Taiwan; Hong Kong; and Subic Bay in the Philippines for repairs after a collision with a barge being towed by RVN tug during a nighttime underway replenishment . On 2 August 1969, Stribling cleared the combat zone to return home. On her way, she stopped at Kure and Yokosuka, Japan; Pearl Harbor; San Diego; Acapulco Mexico, and Panama.

 Passage 2:The Greek peninsula fell under Roman rule in 146 BC, after the Battle of Corinth, when Macedonia became a Roman province. At this time, southern Greece also came under Roman hegemony; however, some key Greek poleis remained partly autonomous and avoided direct Roman taxation. The Hellenistic Kingdom of Pergamon (282–133 BC) was annexed to that territory in 133 BC, when King Attalus III (r. 138–133 BC) willed the lands to Rome; however, the Romans were slow in securing their claim to those lands, and a pretender to the throne of Pergamon, Eumenes III (Aristonicus) led a revolt with the help of the philosopher Blossius, which the Roman army suppressed in 129 BC, when the lands of Pergamon were divided among Rome, the Kingdom of Pontus, and Cappadocia.

"Love Ain't Here Anymore" was their other top 10 entry, which reached number 3 in July. East 17 also had a number-one single in 1994, "Stay Another Day", which stayed there for 5 of its 8 weeks in the top ten. Their other top ten singles were "Around the World" and "It's Alright (both number 3) and "Steam" (number 7). Bon Jovi, Oasis and Eternal had three singles in the top ten in 1994.
