Passage:In 1970, 22-year-old Crespo had dropped out of IST and was eventually drafted into military service in the Portuguese Colonial War. He transferred to Mozambique where his military occupation was to check the cement cargoes from Beira to the Cahora Bassa Dam construction site, near Tete. Some time later, due to his good fluency in English, he was placed in the press office of Kaúlza de Arriaga, the commander in chief of the Portuguese Armed Forces in Mozambique, who had coordinated a massive anti-guerrilla operation against FRELIMO separatists in 1970 - the Gordian Knot Operation. While serving in the army, Crespo also entered the newly created School of Medicine of the University of Lourenço Marques where he would complete a number of academic disciplines but did not graduate.

[EX Q]: Question: How many people lived in Georgia the year the Meskhetian Turks were forced from the Meskheti region? Passage:The Meskhetian Turks first arrived in Azerbaijan at the end of the nineteenth century, and more followed in 1918-1920. However, migration to Azerbaijan increased dramatically after World War II when the Soviet Union was preparing to launch a pressure campaign against Turkey. Vyacheslav Molotov, then Minister of Foreign Affairs, demanded to the surrender of three Anatolian provinces (Kars, Ardahan and Artvin); thus, war against Turkey seemed possible, and Joseph Stalin wanted to clear the strategic Turkish population situated in Meskheti, located near the Turkish-Georgian border which were likely to be hostile to Soviet intentions. Thus, in 1944, the Meskhetian Turks were forcefully deported from the Meskheti region in Georgia and accused of smuggling, banditry and espionage in collaboration with their kin across the Turkish border. Nationalistic policies at the time encouraged the slogan: "Georgia for Georgians" and that the Meskhetian Turks should be sent to Turkey "where they belong". Joseph Stalin deported the Meskhetian Turks to Central Asia (especially to Uzbekistan), thousands dying en route in cattle-trucks, and were not permitted by the Georgian government of Zviad Gamsakhurdia to return to their homeland.
