Passage: Gimbel was born on November 16, 1927 in Brooklyn, New York, the son of Lottie (Nass) and businessman Morris Gimbel. His parents were Austrian Jewish immigrants. Gimbel was self-taught in music and following initial employment with music publisher David Blum, progressed to become a contract songwriter with Edwin H. Morris Music. Small successes and moderate fame came as a result of lively novelty songs "Ricochet", which was popularized in a 1953 recording by Teresa Brewer from which was developed the 1954 Judy Canova film Ricochet Romance, and "A Whale of a Tale", sung by Kirk Douglas in another 1954 production, Disney's 20,000 Leagues Under the Sea. Greater success was earned with Dean Martin's recording of "Sway", which reached #6 on the UK Singles Chart, followed by his first big success, Andy Williams' rendition of "Canadian Sunset", which scored to #1 in 1956.
 Link Information: Williams's third single, "Canadian Sunset", reached No. 7 in the Top Ten in August 1956; it was followed in February 1957 by his only Billboard No. 1 hit, "Butterfly" Question: How many times has the artist whose version of "Canadian Sunset" reached #1 in 1956 had a #1 single?

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?
Answer: 3
