How does the poem’s structure highlight the theme?

Read the selection below and answer the question. an open boat by alfred noyes o, what is that whimpering there in the darkness? 

 'let him lie in my arms. he is breathing, i know.
 look. i'll wrap all my hair round his neck' – the sea's rising,
 the boat must be lightened. he's dead. he must go.' 


 see - quick - by that flash, where the bitter foam tosses, 
 the cloud of white faces, in the black open boat, 
 and the wild pleading woman that clasps her dead lover 
 and wraps her loose hair round his breast and his throat.
 'come, lady, he's dead.' - 'no, i feel his heart beating,
 he's living, i know. but he's numbed with the cold. 
 see, i'm wrapping my hair all around him to warm him.' -
- 'no. we can't keep the dead, dear. come, loosen your hold.

 'come. loosen your fingers.' - 'o god, let me keep him! ' -
 o, hide it, black night! let the winds have their way! 
 and there are no voices or ghosts from that darkness, 
 to fret the bare seas at the breaking of day. the imagery and word choice in the second stanza creates a tone of liveliness and joy danger and gloom silence and peace anger and hostility

The words screaming and rushed in the passage suggest which tone in the story the metamorphosis a.) tense b.) positive c.) fun d.) formal
