Teacher: Now, understand the problem? Solve this instance: Question: What was the population of Athens the year that Xenakis moved there? Passage:In 1938, after graduating from the Spetses school, Xenakis moved to Athens to prepare for entrance exams at the National Technical University of Athens. Although he intended to study architecture and engineering, he also took lessons in harmony and counterpoint with Aristotelis Koundouroff. In 1940 he successfully passed the exams, but his studies were cut short by the Greco-Italian War, which began with the Italian invasion on 28 October 1940. Although Greece eventually won the war, it was not long before the German army joined the Italians in the Battle of Greece, in April 1941. This led to the Axis occupation of Greece during World War II, which lasted until late 1944, when the Allies began their drive across Europe, forcing the Axis forces to withdraw. Xenakis joined the National Liberation Front early during the war, participating in mass protests and demonstrations, and later becoming part of armed resistancethis last step was a painful experience Xenakis refused to discuss until much later in life. After the Axis forces left, Churchill ordered that British forces step in to help restore the Greek monarchy; they were opposed by the Democratic Army of Greece, and the country plunged into a civil war. In December 1944, during the period of Churchill's martial law, Xenakis (who was by then a member of the communist students' company of the left-wing Lord Byron faction of ELAS) became involved in street fighting against British tanks. He was wounded and facially disfigured when shrapnel from a tank blast hit his cheek and left eye, which was blinded; that Xenakis survived the injury has been described as a miracle.
