Final answer:
During the time of Pope Alexander, people believed that he died from accidental poisoning or being poisoned, as suggested by the accusations against the Jews. However, the accuracy of these beliefs is uncertain due to vague historical records.
Step-by-step explanation:
In the context of poisoning accusations during the time of Pope Alexander, it can be said that people believed he died from accidental poisoning or being poisoned. The quote from Galipapa suggests that some blamed the Jews for poisoning the world. However, it is important to consider that this view may have been projected back onto the past rather than being a contemporaneous belief. It is difficult to determine the truth of these claims as historical records from that time are often vague. Therefore, the claim that people believed Pope Alexander died from accidental poisoning or being poisoned can be considered true, but should be approached with caution.
