Final answer:
Ötzi most likely died from a blunt force blow to the head, not from hitting his head on a rock after being struck by an arrow.
Step-by-step explanation:
Based on the available evidence, it is likely that Ötzi, the five-thousand-year-old man found in the alpine region between Austria and Italy, died from a blunt force blow to the head. The injuries found on his skull indicate that he was struck with considerable force, possibly by a heavy object like an axe handle or a sword handle. There is no evidence to suggest that his head injury was caused by hitting his head on a rock after being struck by an arrow.
