In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as 'a' for Yes or 'b' for No.

Example Input: Question: Where was Billboard Frolics' creator born? Passage:Cantor appears in caricature form in numerous Looney Tunes cartoons produced for Warner Bros., although he was often voiced by an imitator. Beginning with I Like Mountain Music (1933), other animated Cantor cameos include Shuffle Off to Buffalo (Harman-Ising, 1933) and Billboard Frolics (Friz Freleng, 1935). Eddie Cantor is one of the four "down on their luck" stars (along with Bing Crosby, Al Jolson, and Jack Benny) snubbed by Elmer Fudd in What's Up, Doc? (Bob McKimson, 1950). In Farm Frolics (Bob Clampett, 1941), a horse, asked by the narrator to "do a canter", promptly launches into a singing, dancing, eye-rolling impression. The Cantor gag that got the most mileage, however, was his oft-repeated wish for a son after five famous daughters. Slap-Happy Pappy (Clampett, 1940) features an "Eddie Cackler" rooster that wants a boy, to little avail. Other references can be found in Baby Bottleneck (Clampett, 1946) and Circus Today (Tex Avery, 1940). In Merrie Melodies, The Coo-Coo Nut Grove Cantor's many daughters are referenced by a group of singing quintuplet girls. In Porky's Naughty Nephew (Clampett, 1938) a swimming Cantor gleefully adopts a "buoy". An animated Cantor also appears prominently in Walt Disney's "Mother Goose Goes Hollywood" (Wilfred Jackson, 1938) as Little Jack Horner, who sings "Sing a Song of Sixpence".

Example Input: Question: Did Sargis Tmogveli survive the capture of the city of Kars? Passage:Shalva was one of the most notable military commanders during a series of expansionist wars waged by the Kingdom of Georgia under Queen Tamar (r. 11841213). He consecutively held top posts of mechurchletukhutsesi (Lord High Treasurer) and mandaturtukhutsesi (Lord High Mandator) at Tamar's court. Together with his brother Ivane, Shalva was in command of vanguard traditionally composed of the Meschian troops from south Georgia. In the battle of Shamkor against the Ildenizid atabeg of Azerbaijan in 1195, he captured a war banner sent by the Caliph to the Muslim army which was then donated to the revered icon of Our Lady of Khakhuli. In 1206/1207, Shalva, together with Sargis Tmogveli, took hold of the city of Kars from the Seljuqs and was appointed as the governor of the Kars county.

Example Input: Question: How long had the Somali Civil War been going on for by the year Mire fled Somalia? Passage:Born in Mogadishu, Somalia in 1977, her father was a police criminal investigator who died of torture and lack of access to medical care due to political and clan-based violence when Mire was 12. After this traumatic experience, in 1991, she fled Somalia with her mother and siblings on a relative's lorry during the Somali Civil War. Mire and her identical twin, Sohur, emigrated to Sweden where an older sister lived and received asylum. The twins later moved to the United Kingdom to study. Mire studied Scandinavian pre-history and archaeozoology at Lund University in Sweden before receiving a BA degree in History of Art/Archaeology of Africa and Asia at SOAS, University of London in 2005, and subsequently an MA in African Archaeology in 2006 and PhD degree in Archaeology in 2009 at University College London.
