Final answer:
Historians consider other factors besides the eruption of Mount Vesuvius that could have led to deaths in Pompeii, such as evidence of pre-eruption evacuation and post-eruption activity indicating survivors and returnees.
Step-by-step explanation:
Evidence from archaeological research has led historians to consider other factors alongside the eruption of Mount Vesuvius in understanding the fate of Pompeii's residents. Excavations indicate that some residents had left the city before the eruption, with houses showing signs of being packed up, suggesting a pre-eruption evacuation. Additionally, valuable objects were found buried or hidden, and there is evidence of people returning post-eruption, implying that the direct impact of the eruption was not the sole cause of death. The eruption involved a series of events, including ash fall and pyroclastic flows, which struck at different times, and different individuals may have perished in various ways at differing stages of the catastrophe.
