[Q]: Passage: Slavic tribes settled in the Balkan region including North Macedonia by the late 6th century AD. During the 580s, Byzantine literature attests to the Slavs raiding Byzantine territories in the region of Macedonia, later aided by Bulgars. Historical records document that in c. 680 a group of Bulgars, Slavs and Byzantines led by a Bulgar called Kuber settled in the region of the Keramisian plain, centred on the city of Bitola, forming a second route for the Bulgar definitive settlement on the Balkan Peninsula at the end of the 7th century. Presian's reign apparently coincides with the extension of Bulgarian control over the Slavic tribes in and around Macedonia. The Slavic tribes that settled in the region of Macedonia converted to Christianity around the 9th century during the reign of Tsar Boris I of Bulgaria. The Ohrid Literary School became one of the two major cultural centres of the First Bulgarian Empire, along with the Preslav Literary School. Established in Ohrid in 886 by Saint Clement of Ohrid on the order of Boris I, the Ohrid Literary School was involved in the spreading of the Cyrillic.

[A]: Answer: 3


[Q]: Passage: The "square" is actually triangular in shape. Immediately to the north, the modern Saïd Business School of Oxford University dominates the square, established in 1996 on the site of the former Oxford Rewley Road railway station. To the east are Hythe Bridge Street (A4144) and Park End Street, both leading into central Oxford. Between them is the Royal Oxford Hotel. To the south, Hollybush Row and then Oxpens Road (A4144 road) act as an inner ring road leading to Abingdon Road, the main arterial road south out of the city. On the corner with Hollybush Row is the old Frank Cooper's jam factory. To the west, Botley Road (A420 road) leads out of the city centre, under a railway bridge just south of the main Oxford railway station, situated to the northwest.
 Link Information:  There is evidence of teaching as early as 1096 Question: How many years after the university was founded was the modern business school established?
[A]: Answer: 900


[Q]: Passage: Spindler was born in Łódź, Poland, to an ethnic German family. He was the son of Gertrud Alma (née Bernewitz) and Oskar Karl Spindler; his father was a businessman. Spindler was considered part of the Volksdeutsche by the Nazi regime, and after the German invasion of Poland in 1939 was required to join the Deutsches Jungvolk (part of the Hitler Youth). When Germany's Eastern Front collapsed in 1944, Spindler and other children of Łódź were evacuated to a rural estate north of the city. In January 1945, he and his companions were forced to flee west on foot to escape the advancing Red Army; many of them were killed by starvation, exposure, or bombing raids. Spindler was eventually reunited with his family in Magdeburg, and they settled in Weißenfels, Saxony-Anhalt, which became part of the Soviet occupation zone and later East Germany. He was blacklisted from attending university due to his anti-Soviet views, and at the age of 17 was granted permission to move to Australia, sponsored by a relative who had settled in Melbourne.
