Question:
The Turkana are a Nilotic people native to the Turkana District in northwest Kenya, a semi-arid climate region bordering Lake Turkana in the east, Pokot, Rendille and Samburu people to the south, Uganda to the west, and South Sudan and Ethiopia to the north. They refer to their land as Turkan. According to the 2009 Kenyan census, Turkana number 855,399, or 2.5% of the Kenyan population, making the Turkana the third largest Nilotic ethnic group in Kenya, after the Kalenjin and the Luo, slightly more numerous than the Maasai, and the tenth largest ethnicity in all of Kenya. Although this figure was initially controversial and rejected as too large by Planning Minister Wycliffe Oparanya, a court ruling (Feb 7, 2012) by Justice Mohammed Warsame (judge) stated that the Kenyan government accepts the 2009 census figures for Turkana.
The Turkana entered Turkana basin from the north as one unit of the Ateker confederation. This cluster split as a result of internal differences, leading to the emergence of distinct independent groups. The Turkana people emerged as a victorious group in the subsequent conflict, which led to enmity between the Turkana and other Ateker cluster groups, who formed military alliances against the Turkana. The Turkana emerged victorious again by co-opting young people from conquered groups. The military power and wealth of the Turkana increased in what is now the northern plains of Turkana. The establishment of the Turkana people developed as a distinct group which expanded southwards conquering ethnic nations south of its borders. The Turkana people easily conquered groups it came in contact with by employing superior tactics of war, better weapons and military organization. By the 1600s, the Turkana basin had been fully occupied by the Turkana and their allies. There was a relative long period of peace among indigenous ethnic communities around Turkana until the onset of European colonization of Africa. Sporadic conflicts involved Turkana fights against Arab, Swahili and Abyssinian slave raiders and ivory traders. European colonization brought a new dimension to conflict with Turkana putting up a lasting resistance to a complex enemy, the British. The Turkana put up and maintained active resistance to British colonial advances leading to a passive presence of colonial administration. By the outbreak of World War I, few parts of Turkana had been put under colonial administration. From World War I through to the end of World War II, Turkana actively participated in the wars as allies of Britain against invading Italy. Turkana was used as the launching pad for the war against invading Italian forces leading to the liberation of Abyssinia. After World War II, the British led disarmament and pacification campaigns in Turkana, leading to massive disruptions and dispossession of Turkana pastoralists. The colonial administration practiced a policy of deliberate segregation of Turkana people by categorizing Turkana Province as a closed district. This led to marginalization and underdevelopment in the lead up to Kenya's independence.

Question:
Rascal Flatts is an American country band formed in Columbus, Ohio in 1999. It is composed of Gary LeVox, his second cousin Jay DeMarcus and Joe Don Rooney. DeMarcus is also a brother-in-law of country music singer James Otto, and formerly one-half of the Christian music duo East to West. They are best known for performing a cover of Tom Cochrane's "Life Is a Highway".
Rascal Flatts' founding was at Fiddle and Steel Guitar Bar in Nashville, Tennessee. Gary LeVox and Jay DeMarcus are second cousins from a musical family. DeMarcus moved to Nashville in 1992, earning his first record deal as part of a Christian group called East to West; his brother-in-law, James Otto, is also a country music singer. In 1997, DeMarcus called LeVox, and convinced him to come to Nashville and provide some harmonies on Michael English's album Gospel, which he was producing. They engineered the album together, and became English's back-up band. At the same time, DeMarcus had become the bandleader of Chely Wright's band, where he met Joe Don Rooney, the guitarist in that band. DeMarcus and LeVox were working in a Printer's Alley nightclub and when their part-time guitarist could not make it one night, DeMarcus invited Rooney to join them. Jim Riley was the drummer and bandleader for the band. The group covered the hit Shenandoah single The Church on Cumberland Road that night. To the group's recollection, a bond was formed instantly. Singer Mila Mason recommended the group to record producers Mark Bright and Marty Williams, who played Lyric Street Records A&R Doug Howard a three-song demo and Howard thought they were "just incredible." After he'd heard the demos, the band went into the Lyric Street offices the next day, sat down with acoustic guitars, and played a couple of songs. According to Howard in an interview with HitQuarters: "The vocals and harmonies, it was all there--I was just blown away. The lead singer has such a unique and compelling voice." The band was signed to Lyric Street in late 1999.
