Final answer:
Beowulf displays extraordinary feats that characterize him as an epic hero, including ripping off Grendel's arm, swimming for half a day, lifting a heavy sword, and diving into a fiery lake.
Step-by-step explanation:
The question pertains to the epic poem Beowulf, wherein the protagonist displays extraordinary strength and bravery, akin to what one might consider superhero powers in contemporary fiction. Some examples of these powers that Beowulf displays in the text include his ability to rip an arm off of the monstrous Grendel, his feat of swimming for an extended period (half a day), his strength to lift a heavy sword that was hard for others to handle, and his daring dive into a fiery lake during his battle with the dragon. These feats highlight Beowulf's exceptional abilities and are characteristic of an epic hero.
As for examples of feats that are technically possible but not common or practical, one might consider someone performing a single-handed lift of an exceedingly heavy object, such as a large boulder; another could be a marathon runner maintaining a sprinter's pace throughout the entire distance; or a diver holding their breath underwater for an extended period, well beyond the average human capacity.
the correct option is B
