Teacher: Now, understand the problem? Solve this instance: Question: How long did the war that created tense relations between Georgia and Russia last? Passage 1:Prior to the 2016 Contest, Georgia had participated in the Eurovision Song Contest eight times since their first entry in 2007. The nation's highest placing in the contest, to this point, has been ninth place, which was achieved on two occasions: in 2010 with the song "Shine" performed by Sofia Nizharadze and in 2011 with the song "One More Day" performed by Eldrine. The nation briefly withdrew from the contest in 2009 after the European Broadcasting Union (EBU) rejected the Georgian entry, "We Don't Wanna Put In", for perceived political references to Vladimir Putin who was the Russian Prime Minister at the time. The withdrawal and fallout was tied to tense relations between Georgia and then host country Russia, which stemmed from the 2008 Russo-Georgian War. Following the introduction of semi-finals, Georgia has, to this point, failed to qualify to the final on only two occasions. In , Georgia qualified to the final where the country placed 11th with the song "Warrior" performed by Nina Sublatti.
Passage 2:Arthur Evelyn St. John Waugh was born on 28 October 1903 to Arthur Waugh (18661943) and Catherine Charlotte Raban (18701954), into a family with English, Scottish, Welsh, Irish and Huguenot origins.
