Explanation:

The proof that Beowulf offers to show that he is up to the challenge of killing Grendel is to tell stories of his past victories over mighty men and other monsters.

Beowulf is a mighty warrior who comes to the aid of a country that is tormented by the monster Grendel so he talks about his achievements to prove that he is capable of killing Grendel.

End of the story is horrifying and shocking: Montresor traps and entombs living Fortunato behind the brick wall. The victim cries to the executioner: "For the love of God"(Poe, 214) but the only respond is ironical repeat of his own words.
