Question: How old was Selimovic when the Second World War began? Passage:Selimovic was born to a prominent Muslim family of Serbian origin on 26 April 1910 in Tuzla, Bosnia and Herzegovina, where he graduated from elementary school and high school. In 1930, he enrolled to study the Serbo-Croatian language and literature at the University of Belgrade Faculty of Philology and graduated in 1934. His lecturers included Bogdan Popovic, Pavle Popovic, Vladimir Corovic, Veselin Cajkanovic, Aleksandar Belic and Stjepan Kuljbakin. In 1936, he returned to Tuzla to teach in the gymnasium that today bears his name. At that time he participated in the Soko athletic organisation. He spent the first two years of the Second World War in Tuzla, until he was arrested for participation in the Partisan anti-fascist resistance movement in 1943. After his release, he moved to liberated territory, became a member of Communist Party of Yugoslavia and the political commissar of the Tuzla Detachment of the Partisans. During the war, Selimovic's brother, also a communist, was executed by partisans' firing squad for alleged theft, without trial; Selimovic's letter in defense of the brother was to no avail. That episode apparently affected Mesa's later contemplative introduction to Death and the Dervish, where the main protagonist Ahmed Nurudin fails to rescue his imprisoned brother.
