Answer:
Lines 18-25 express an atmosphere of exaltation and administration.
Explanation:
Lines 18-25 have a strong descriptive language, through the constant use of adjectives and nouns that show how Beowulf was admired and exalted by the people of his homeland. It also shows how well-liked he was and a strong support for his father and his kingdom by attracting many warriors and vassals who were loyal to him on account of everything he represented.
This all gives a tone of exaltation and admiration to Beowulf, showing that he was a long-awaited heir and that he does not discourage or compromise the trust that everyone has in him.
