Final answer:
The statement about Beowulf's strength being equal to that of thirty men in his handgrip is true, reflecting the use of hyperbole in the epic poem to highlight his superhuman heroism.
Step-by-step explanation:
The statement that Beowulf is so strong that he has the strength of thirty men in the grip of his hand is true. This is an example of hyperbole, a literary device often used in epic poetry to emphasize the heroic qualities of the protagonist. In the epic poem Beowulf, this exaggeration underscores the superhuman strength and heroism of Beowulf, setting him apart from ordinary men as he takes on monstrous creatures like Grendel, Grendel's mother, and the dragon.
