Question: In what year was the university established where Friedrich Hornemann studied Arabic. Passage 1:Hornemann was born in Hildesheim, a city in Lower Saxony, Germany, located about 30km southeast of Hannover. He was a young man when, early in 1796, he offered his services to the African Association of London as an explorer in Africa. The African Association sent him to the University of Gottingen to study Arabic and otherwise prepare for an expedition from the east into the unknown regions of North Africa. In September 1797 he arrived in Egypt, where he continued his studies. When the country was invaded by the French, he was confined in the citadel of Cairo to preserve him from the fanaticism of the populace. Liberated by the French, he received the patronage of Bonaparte. On 5 September 1798 he joined a caravan returning to the Maghreb from Mecca, attaching himself to a party of Fezzan merchants who accompanied the pilgrims. As an avowed Christian would not have been permitted to join the caravan Hornemann assumed the character of a young mamluk trading to Fezzan. He then spoke, but indifferently, both Arabic and Turkish, and he was accompanied as servant and interpreter by Joseph Freudenburg, a German convert to Islam, who had thrice made the pilgrimage to Mecca. Travelling by way of the oases of Siwa and Aujila, a black rocky desert was traversed to Temissa in Fezzan. Murzuk was reached on 17 November 1798.
Passage 2:Smith played four years at San Jose State University and had 13 career interceptions, the second-most in school history. He joined the team as a walk-on in 1995 and was assigned to cover Keyshawn Johnson in his first collegiate start. He led San Jose State with nine passes broken up in 1996 and 16 in 1997. He tied for second in the nation in 1997 with seven interceptions and tied a school record with three interceptions against the University of Hawaii. Smith returned 22 punts for 246 yards and was the only player in Division I-A to rank in the top-30 in both interceptions and punt returns. He had an 84-yard touchdown return at UTEP in 1997 and an 88-yard punt return for a touchdown against Fresno State in 1998. Smith had 74 tackles as a sophomore, third-most on the team, and ended his career with 182 career tackles.
Passage 3:Underwater hockey (UWH), also known as Octopush (mainly in the United Kingdom) is a globally played limited-contact sport in which two teams compete to manoeuvre a puck across the bottom of a swimming pool into the opposing team's goal by propelling it with a hockey stick (pusher). It originated in England on November 18 1954 when Alan Blake, a founder of the newly formed Southsea Sub-Aqua Club, invented the game he called Octopush as a means of keeping the club's members interested and active over the cold winter months when open-water diving lost its appeal. Underwater hockey is now played worldwide, with the Confederation Mondiale des Activites Subaquatiques, abbreviated CMAS, as the world governing body. The first Underwater Hockey World Championship was held in Canada in 1980 after a false start in 1979 brought about by international politics and apartheid.
