Question: How long had California been a state for by the year Dodds moved there? Passage:Dodds gained a reputation as a top young drummer in New Orleans. In 1918, Dodds left Sonny Celestin's outfit to play in Fate Marable's riverboat band. A young Louis Armstrong also joined the band, and the two of them were on the boats for three years (from 1918 to 1921). The band played on four different boats, and usually left New Orleans in May and travel to St. Louis, though they also sometimes traveled further north. They played jazz, popular, and classical music while on the boats. Dodds and Armstrong left Fate Marable's band in 1921 due to a disagreement about musical style, and Dodds soon joined King Oliver's Creole Jazz Band. At this time, the personnel in Oliver's band were Joe "King" Oliver on cornet, Baby Dodds' brother Johnny Dodds on clarinet, Davey Jones on alto saxophone, Honore Dutrey on trombone, Lil Hardin on piano, Jimmy Palao on violin, and Eddie Garland on bass fiddle. They moved to California in 1921 to work with Oliver there, and they played together for about fifteen months. In 1922, the band, excepting Garland, Palao, and Jones, followed Oliver to Chicago, which would be his base of operations for several years. They began playing at the Lincoln Gardens, and Louis Armstrong also joined this outfit. Dodds describes playing with this band as "a beautiful experience". Dodds recorded with Louis Armstrong, Jelly Roll Morton, Art Hodes, and his brother Johnny Dodds. Dodds played in Louis Armstrong's Hot Five and Hot Seven groups. In May 1927 Armstrong recorded with the Hot Seven, which consisted of Johnny Dodds, Johnny St. Cyr, Lil Hardin Armstrong, John Thomas, Pete Briggs, and Baby Dodds. From September to December 1927 the Hot Five Armstrong assembled consisted of Johnny Dodds, Kid Ory, Johnny St. Cyr, Lonnie Johnson, and Baby Dodds.

Question: During what years did the Norman conquest of England occur? Passage:It was founded around 1072 as a Benedictine priory by William FitzOsbern and his son Roger de Breteuil, 2nd Earl of Hereford. FitzOsbern had been granted the Lordship of Striguil by his second cousin King William in gratitude for his support in the Norman conquest of England, and was responsible for starting the building of a new castle overlooking the River Wye on the border with the kingdoms of Wales. At the same time he established a nearby monastic cell, so as to collect rent from the lands within Gwent which he had granted to his home Priory of Cormeilles in Normandy. By the early 12th century, the monastic establishment, on a ridge overlooking the river about 300 metres from the castle, had the status of an alien priory in its own right, though it probably never held more than about 12 monks. It superseded an earlier Augustinian priory located about 2km away, which was dedicated to the Welsh saint Cynfarch (or St. Kingsmark), a disciple of St. Dyfrig.

Question: Did Blake or Philby defect first? Passage:In May 1986, Souther requested Soviet citizenship, aware that the investigation against him was progressing. In June, fearing imminent arrest, Souther defected to the Soviet Union by flying from the United States to Rome, where the Soviet intelligence services transferred him to Moscow. Initially, Soviet counterintelligence units were suspicious of Souther's defection and feared that he was a double agent for the CIA, but he was cleared shortly afterwards. On 2 October 1986, Souther was granted Soviet citizenship in a decree from the Presidium of the Supreme Soviet, and adopted the Russian name Mikhail Yevgenyevich Orlov. Souther was well-received by the Soviet authorities, gifting him an apartment in Moscow and a dacha on the outskirts of the city, and promoting him to the rank of major in the KGB one of few foreign spies to be commissioned as an officer in the agency. Souther became actively engaged in scientific activities, developed his own English teaching program, walked around Moscow a lot, and travelled to other Soviet cities. Souther met and befriended other foreign Soviet intelligence agents that had defected including Kim Philby and George Blake.

In early 1989, Souther was awarded an Order of Friendship of Peoples for his contributions in the intelligence services following a petition from the KGB leadership.
