Input: Consider Input: 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.
 Link Information: The 6th century Byzantine historian Jordanes, wrote in his 551 AD work Getica: "although they derive from one nation, now they are known under three names, the Veneti, Antes and Sclaveni" Question: How many different slavic tribes were there in the 6th century?

Output: Answer: 3


Input: Consider Input: Passage: He was present at the Battle of Manzikert in 1071, where he refused to join the fray; the battle proved to be a disastrous defeat for the Byzantines. Despite this treachery, he was kept in imperial service, where good generals were needed, and was sent into Asia Minor again with a force of 3,000 Franco-Norman heavy cavalry. There Roussel conquered some territory in Galatia and declared it an independent state in 1073, with himself as prince, following the example set by his fellow Normans in the Mezzogiorno. His capital was Ankara, now the capital of Turkey. He defeated the Caesar John Ducas and sacked Chrysopolis, near Constantinople. He even supported a usurper candidate, but by formally ceding lands that the Seljuk Turks had actually conquered, the emperor Michael VII persuaded the Seljuk warlord Tutush I to remove Roussel. However both Ducas and Roussel were defeated and captured by Turkish forces, fortunately for Roussel his wife was able to pay the ransom demanded by the Turks allowing Roussel to return to Amasea, where the population so loved him that he made himself undisputed governor. He was given up by the people through a ploy of Alexius Comnenus (1074), then a general, later an emperor.

Input: Consider Input: Passage: Much as was the case of the concurrent development of professional gridiron football, the Pittsburgh, Pennsylvania metropolitan area was one of the first areas to promote a professional ice hockey team. The Western Pennsylvania Hockey League began hiring professional players in 1902 and acted as a pro–am league. This league joined with teams in Michigan and Ontario to form the International Professional Hockey League in 1904, with Houghton, Michigan dentist Jack Gibson its founder. While this league had folded by 1907, it was the start of professional hockey. The United States would continue to see professional hockey with teams from the PCHL, beginning with the Portland Rosebuds, followed by a Seattle-based franchise a year later. When the Boston Bruins joined the NHL in 1924, the United States was finally represented in the league. It would continue to grow in the NHL until a peak in the 2000s (decade), when 24 of the NHL's 30 teams were in the United States (the loss of the Atlanta Thrashers to Winnipeg in 2011 reduced this number to 23; it returned to 24 American teams when the Vegas Golden Knights joined in 2017). The NHL will reach a higher peak when the Seattle expansion franchise joins the league in 2021-22 as the 25th American team. There are several other pro leagues in the US as well; as of 2019 these include the AHL, ECHL, SPHL, and FPHL. The AHL and ECHL are official minor leagues to the NHL, with the ECHL subservient to the AHL; the FPHL and SPHL operate as low-level independents.
