Question: Which team won the All-Star Game where Yost was a reserve player? Passage:In 1950, Yost posted career-highs with a .295 batting average and a .440 on-base percentage. In 1951 he led the American League with 36 doubles and produced a career-high 65 runs batted in. He earned a place as a reserve player for the American League team in the 1952 All-Star Game. Between August 30, 1949 and May 11, 1955, Yost played in 829 consecutive games for the Senators, the ninth longest consecutive game streak in major league history. Yost's home run totals were diminished by having to play his home games in Washington's cavernous Griffith Stadium. Between 1944 and 1953, he hit only 3 home runs at home while hitting 52 home runs on the road.

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: What is the distance between Qus and Sudan? Passage:Despite that it was unusual for women to participate in archaeology at the time, in 1901, encouraged by Howard Carter, Lady William Cecil began excavations at Qubbet el-Hawa near Aswan. Her family was wintering in the area and while exploring on the west bank of the Nile had discovered what she thought might be an ancient cemetery. Carter, who in 1899 had been appointed by the Antiquities Service as one of two European Chief Inspectors and in charge of excavations in the Nile Valley south from Qus to the Sudanese border, came to see the find the following day. He arranged for permits to excavate and provided an inspector and workers to assist in the dig. She kept a diary of the details of the expedition in which multiple tombs were found, as well as wooden anthropoid coffins of the Saite Era. Though the entire necropolis was infested with termites, Tomb 21 yielded two burial boxes. The male's coffin disintegrated when it was touched, but the female's coffin remained intact and was removed. The exterior was painted in yellow and devoid of any inscription. The mummy was covered with a blue network of beading. A coarse blue glaze was used on the winged scarabs and Amenti gods depicted on the canopic jars. The sole adornment of the mummy was a one inch by half inch opaque green stone. Lady William's diary recorded that the names found in the tomb were Bao-bao, daughter of Pawebas and Shepentanefet and her brother Waher. She also reported remnants of a former burial, which may have been the tomb of Shepentanefret.
