Question: Who won the season of X factor that Cowell was a judge with newcomer Rita Ora? Passage:In October 2013, it was reported that Cowell may return to the UK version of The X Factor for series 11 in the place of Gary Barlow, and on 7 February 2014, his return was officially confirmed. This resulted in the cancellation of the US version after three seasons by Fox. He joined judges Louis Walsh, Cheryl Fernandez-Versini, and new judge, former Spice Girls member Mel B, who replaced Nicole Scherzinger. For his eighth series, he was given the Over 25s category. On 13 December, Ben Haenow and Fleur East reached the final two, which meant that Cowell was the winning mentor for the first time since series 3 in 2006, when he had both Leona Lewis and Ray Quinn in the final. Haenow became the eleventh winner on 14 December. In March 2015, it was announced that Cowell would return to the X Factor for its twelfth series along with veteran judge Cheryl Fernandez-Versini, and newcomers Rita Ora and BBC Radio 1 DJ Nick Grimshaw.

Question: Did the group that Stinson founded have more than three members? Passage:Gregory E. Stinson, better known as G. E. Stinson (born in Kingfisher, Oklahoma), is an American guitarist and founding member of new age/electronic musical group Shadowfax. Inspired by blues masters such as Bo Diddley and Muddy Waters, Stinson experimented with blues, jazz and other musical genres before co-founding Shadowfax in 1974. He remained with the band for six albums. He departed Shadowfax after recording The Odd Get Even (1989), entering the Los Angeles underground music community to refine his 'extended technique' and 'frequency manipulation'. Since then he has worked with a number of musicians on various projects, including Napalm Quartet, Splinter Group, Stinkbug, Metalworkers, Alex De Grassi, Devin Sarno and others. In 2000, he collaborated with drummer Gregg Bendian, violinist Jeff Gauthier, and bassist Steuart Liebig on an album of collective improvisational pieces recorded live in the studio, entitled Bone Structure. Released in 2003, it was given four stars by Jim Andrews in DownBeat magazine.

Question: What is the average depth of the lake that is located near Kilekwa's place of birth? Passage:Kilekwa was born in Zambia, in a Bissa village, in the Mbisa tribe, near Lake Bangweulu. He was born "Chilekwa"; Ki-, he says in his autobiography, "is a Swahili prefix". He was enslaved in the 1870s as a boy in what he called "the Maviti wars" (the term may point to "any brigand rather than to a specific ethnic group"). His mother was unable to pay his ransom — eight yards of calico cloth—and he was taken to the coast, headed for the Persian Gulf. However, the ship of his enslavers was stopped by the Royal Navy; HMS Osprey took them to Muscat. The group spent a month or so there, but then Kilekwa and another boy, Mambwala, were volunteered to serve on the Osprey and become seamen. They did odd jobs while the Osprey, looking for slave dhows, sailed throughout the Gulf and up the Euphrates to Basra (in present-day Iraq). One day, while most of the sailors were on shore in Bushehr, Persia, slavers tried to kidnap them but were prevented. They traveled as far as India and went sightseeing in Bombay. When the Osprey was to return to England, the two were transferred to HMS Bacchante; they were in Bombay again for the Golden Jubilee of Queen Victoria in 1887.
