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: Strutt was baptised at Springfield, Essex, on 26 February 1762, the second son of John Strutt, of Terling Place, Essex, by Anne, daughter of the Rev. William Goodday of Maldon. Entering the army in 1778, he joined his regiment, the 61st, at Minorca. Later he was appointed to a company in the 91st, and took part in the defence of St. Lucia. In 1782, having exchanged into the 97th, he served at the siege of Gibraltar. On the signing of the preliminaries of peace he purchased a majority in the 60th regiment, and, being placed on half-pay, visited several German courts. In 1787 he was sent with his regiment to the West Indies, where he took an active part in military affairs. Succeeding to a lieutenant-colonelcy by special command of George III, he was removed to the 54th, and went with the army of Lord Moira to Flanders. In 1794 he bore a very distinguished part against the French at Tiel, going through much hard fighting. On his return he was sent to St. Vincent, where he was raised to the rank of brigadier-general. In January 1796, with two hundred men, he attacked a force of twelve hundred, being himself thrice wounded, and losing his right leg. On his return to England he was received with marked favour by the king, and on 23 February 1796 was made deputy governor of Stirling Castle, afterwards serving upon the staff in Ireland. On 23 June 1798 he was raised to the rank of major-general, and on 13 May 1800 he was, as a reward for his services, appointed to the sinecure office of governor of Quebec, and he held that post until his death. He died at Tofts, Little Baddow, Essex, on 5 February 1848, having seen an exceptional amount of military service, both at home and abroad.
