question:
Passage: Born in Hirschberg on the Saale in the Principality of Reuss-Gera, Germany, Mutschmann moved while he was young with his family to Plauen in Saxony. He served an apprenticeship as an embroiderer and from 1896 to 1901 was employed as a master embroiderer, department head and warehouse director in lace and linen factories in Plauen, Herford and Köln. This was followed by military service from 1901-1903, after which he returned to employment in the Plauen Lace Factyory (Plauener Spitzenfabriken). He established his own lace factory, Mutschmann & Eisentraut, in Plauen in October 1907. During World War I, he served on the Western Front until he was severely wounded in April 1916. He was discharged from the Army as unfit for field service on 24 December 1916, then resuming the direction of his factory in Plauen. After the war, he was an early participant in the nationalist and anti-semitic Deutschvölkischer Schutz und Trutzbund. He was a founding member of the local branch (Ortsgruppe) of the National Socialist German Workers Party (NSDAP) in Plauen and made personal donations of capital to the Nazi Party.

question:
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:
Answer: 3


question:
Passage: In a highly unusual situation, two LP albums of the score were released. The recording rights had been granted to RCA Victor, which had invested in the show, but Merman was under contract to Decca Records, which refused to allow her to record the original cast album. Decca issued a 10-inch LP featuring Merman singing some of her songs, accompanied by arranger-conductor Gordon Jenkins and His Orchestra and Chorus, with vocalizing by Dick Haymes (who joined Merman in the show's biggest hit, "You're Just in Love", their single reaching Billboard magazine's number 30 for a week) and Eileen Wilson (who sang "It's a Lovely Day Today" with Haymes). RCA Victor went ahead with the original cast album replacing Merman with Dinah Shore. Merman was called back into the Decca studios to record additional songs from the show, and the label quickly re-released the album as a 12-inch LP under the title Ethel Merman: 12 Songs from Call Me Madam. The Victor album sold reasonably well, attaining the sixth spot on the Billboard popular album charts, but the LP was out of print from 1956 until RCA Red Seal reissued it briefly in 1977. Peaking at number two on Billboards popular album charts, Merman's Decca recording, which would appear on MCA Records beginning in 1973, stayed steadily in print until the end of the LP era. Merman's Madam album currently is available on a Decca Broadway CD, which also features Merman singing four Cole Porter tunes from the stage score of Panama Hattie (1940).
