Final answer:
The city Giorgi lived in is likely Tbilisi, the capital of Georgia, which is connected to Joseph Stalin's early revolutionary work as explored in Montefiore's biography 'Young Stalin'.
Step-by-step explanation:
The city mentioned in relation to Giorgi in the context provided would be Tbilisi, the capital of Georgia. This is because Montefiore's biography 'Young Stalin' explores Stalin's early revolutionary work specifically in Georgia, and Stalin's real name was Ioseb Besarionis dze Jughashvili, known to his peers as Soso, which was later changed to Josef Stalin. As Georgia was the region of Stalin's early revolutionary activities, it is logical to deduce that Giorgi, a commonly used Georgian name, would be associated with Tbilisi. Furthermore, considering the historical period alluded to in the reference, it is significant to note that Georgia was part of the Soviet Union during Stalin's time.
