Input: Question: Are there any universities in the location where Errol started his career? Passage 1:In the meantime, the Germanic tribe of the Bavarii (Bavarians), vassals of the Franks, had developed in the 5th and 6th century in the west of the country and in what is now known as Bavaria, while what is today Vorarlberg had been settled by the Alemans. In the northern alps the Bavarians had become established as a stem dukedom around 550 AD, under the rule of the Agilolfings until 788 as an eastern outpost of the Frankish Empire. At that time the lands occupied by the Bavarians extended south to current South Tyrol, and east to the river Enns. The administrative center was at Regensburg. Those groups mixed with the Rhaeto-Romanic population and pushed it up into the mountains along the Puster Valley.
 Passage 2:Emanuelson began his career in Nieuw Nickerie, Suriname, in the youth ranks of Santos at age 14. In 1970, he moved to Paramaribo to play in the youth teams of Tuna with whom he won the youth championship. In 1975, he made the move to SV Robinhood where he played as a forward forming the attack of Robinhood together with Rinaldo Entingh and Roy George. In 1976, he made a name for himself in a friendly fixture against Dutch club Ajax while Robinhood were on a tour of the Netherlands. He helped Robinhood to win three national titles in 1975, 1976 and 1979, and was the league top scorer for three consecutive seasons in 1976, 1977 and 1978. He also helped Robinhood to placement in the CONCACAF Champions' Cup finals, where they would finish as runners-up twice, conceding to C.D. Águila from El Salvador in 1976 and Mexican side Club América in 1977. On 30 July 1979 Robinhood were granted permission by the SVB to loan Emanuelson to Belgian side Sint-Niklaas where he played for one season.
 Passage 3:Ancient historians, as well as modern ones, have also written on Alexander's marriage to Roxana the beautiful [Persian]n woman. Robin Lane Fox writes, "Roxana was said by contemporaries to be the most beautiful lady in all Asia. She deserved her name of Roshanak, meaning 'little star', (probably rokhshana or roshana which means light and illuminating) in Persian. Marriage to a local noble's family made sound political sense, but contemporaries implied that Alexander, aged 28, also lost his heart. A wedding-feast for the two of them was arranged high on one of the Persian rocks. Alexander and his bride shared a loaf of bread, a custom still observed in Turkestan. Characteristically, Alexander sliced it with his sword. Ulrich Wilcken writes, "The fairest prize that fell to him was Roxana, the daughter of Oxyartes, in the first bloom of youth, and in the judgment of Alexander's companions, next to Stateira the wife of Darius, the most beautiful woman that they had seen in Asia. Alexander fell passionately in love with her and determined to raise her to the position of his consort."
