[Q]: 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.

[Q]: Question: Which baseball team that played in the 1924 World Series had won the most League pennants? Passage:The 1924 World Series was the championship series of the 1924 Major League Baseball season. A best-of-seven playoff, the series was played between the American League (AL) pennant winner Washington Senators and the National League (NL) pennant winner New York Giants. The Senators defeated the Giants in seven games to win their first championship in club history. The Giants became the first team to play in four consecutive World Series, winning in 1921–1922 and losing in 1923–1924. Their long-time manager, John McGraw, made his ninth and final World Series appearance in 1924. The contest concluded with the second World Series-deciding game which ran to extra innings (the first had occurred in 1912). Later, the Senators would reorganize as the Minnesota Twins, again winning the World Series in 1987 and in 1991.

[Q]: Question: Which country was Thordön repaired in after being salvaged on August 4th? Passage:Thordön (later spelled Tordön) was laid up in reserve in 1868 and 1869. She was rearmed with 240-millimeter M/69 guns (serial numbers 5 and 6) in 1872, but was laid up again from 1874 to 1882. The ship ran aground and sank on Lilla Rimö Island, off Norrköping, on 23 July 1883. She was salvaged on 4 August and managed to proceed under her own power to Karlskrona Naval Dockyard for repairs. The subsequent court-martial ordered the ship's captain to pay for the costs of the salvage and repairs, despite a misplaced buoy that caused the ship to ground. She was recommissioned in 1885 and 1888–89 before being placed back in reserve. Tordön was reconstructed in 1903–05; she received a pair of new Bofors M/94 guns that were given elevation limits of −7° and +15°. The ship also received eight 57-millimeter guns and new boilers. She was reactivated during World War I and assigned to the Gothenburg local defense flotilla in company with her sister Tirfing. Both ships were decommissioned in 1922 and sold the following year. Their new owner converted them into barges and used them in Stockholm harbor.
