An urban civilization, the Garamantes, arose around 500 BCE in the heart of the Sahara, in a valley that is now called the Wadi al-Ajal in Fezzan, Libya. The Garamantes achieved this development by digging tunnels far into the mountains flanking the valley to tap fossil water and bring it to their fields. The Garamantes grew populous and strong, conquering their neighbors and capturing many slaves (which were put to work extending the tunnels). The ancient Greeks and the Romans knew of the Garamantes and regarded them as uncivilized nomads. However, they traded with the Garamantes, and a Roman bath has been found in the Garamantes capital of Garama. Archaeologists have found eight major towns and many other important settlements in the Garamantes territory. The Garamantes civilization eventually collapsed after they had depleted available water in the aquifers and could no longer sustain the effort to extend the tunnels further into the mountains.
How many towns are believed to be found by Archaeologists?
eight major towns

A national university is generally a university created or run by a national state but at the same time represents a state autonomic institution which functions as a completely independent body inside of the same state. Some national universities are closely associated with national cultural or political aspirations, for instance the National University of Ireland in the early days of Irish independence collected a large amount of information on the Irish language and Irish culture. Reforms in Argentina were the result of the University Revolution of 1918 and its posterior reforms by incorporating values that sought for a more equal and laic higher education system.
In what year did Argentina's University Revolution occur?
1918
