Question: What year did Vaughn's producer form hiw own label after leaving Mercury? Passage:In 1971, Bob Shad, who had worked with her as producer at Mercury, asked her to record for his label, Mainstream, which he had founded after leaving Mercury. Breaking a four-year hiatus, Vaughan signed a contract with Mainstream and returned to the studio for A Time in My Life, a step away from jazz into pop music with songs by Bob Dylan, John Lennon, and Marvin Gaye arranged by Ernie Wilkins. She didn't complain about this eclectic change in direction, but she chose the material for her next album after admiring the work of Michel Legrand. He conducted an orchestra of over one hundred musicians for Sarah Vaughan with Michel Legrand, an album of compositions by Legrand with lyrics by Alan and Marilyn Bergman. The songs brought some of the musicians to tears during the sessions. But Shad wanted a hit, and the album yielded none. She sang a version of the pop hit "Rainy Days and Mondays" by the Carpenters for Feelin' Good. This was followed by Live in Japan, her first live album since 1963. Sarah Vaughan and the Jimmy Rowles Quintet (1974) was more experimental, containing free improvisation and some unconventional scatting.

Question: Did Charles Jones win any tests in the Caribbean? Passage:In 1930, when the MCC visited the Caribbean under the leadership of F.S.G. Calthorpe, Jones played against them three times in February, twice for British Guiana and once whilst making his Test Match debut. His selection for the 3rd Test of the four-match series, played at Bourda, Georgetown was more to do with the West Indies' usual policy of using a few players from the host island in an effort to keep the expenses down. In an historic victory over England, Jones' contribution was minimal, scoring just 6 and 2, taking two catches but failing to take a wicket with the ball. He played only occasionally for the next five years but aided by some useful scores with the bat in that time, Jones made a further three Test appearances against England sides led by R.E.S. Wyatt in 1935. In the second Test of the series, played at Port-of-Spain, Trinidad, and where he opened with C.M. Christiani, he scored 19 runs in both innings. This subsequently proved to be his highest Test score but he failed to take a single Test wicket in his career. In all first-class matches he took 24 wickets at an average of 44.12 apiece and scored 917 runs at an average of 21.83. In a career that ended in January 1939, his highest score was an unbeaten 89, scored at home in a comprehensive victory over Barbados. No Obituary appeared within the pages of Wisden for Jones.

Question: How many years after the Treaty of Pozvol concluded did the Livonian War end? Passage:With the Treaty of Pozvol, concluded in 1557, the Livonian Confederation had turned to Poland-Lithuania for protection, triggering Ivan IV of Russia's intervention in what was to become the Livonian War. In 1558, Ivan IV had conquered the Dorpat (Tartu) area, annihilating the Bishopric of Dorpat. With the Treaty of Vilnius of 31 August 1559, Gotthard von Kettler, Grand Master of the Livonian Order, had put the order's lands under protection of Polish king and Grand Duke of Lithuania, Sigismund II Augustus. The order ceded about one seventh of its territory, allowed Sigismund to garrison its most important castles, and agreed to share with him any conquests made from Ivan IV. The alliance was intended to neutralize the imminent threat of annexation of the order's lands by Russia, yet despite earning military support from Polish-Lithuanian chancellor Mikoaj "the Black" Radziwi, Kettler was defeated in Ergeme (Ermes, 1560) and unable to prevent the occupation of most of Livonia by Russian forces. After the treaty, the disintegrating order agreed to secularization if necessary, and since Sigismund was reluctant to support it militarily, continued its search for a protector at the courts of Denmark-Norway and the Holy Roman Emperor.
