What is one way the structure of the fly best reflects the poems literal meaning

The structure of “The Fly” by William Blake the theme of quality and quantity of human life that is taken for granted is best reflects the poem’s rhyme. The rhyme in “The Fly” is ABCB throughout the poem, except the last stanza in which the rhyme is changed in AABA. Changing the rhyme links together “I” and “Fly” which contributes to his argument that human life can be as easily ended as the life of a fly. Using iambic dimeter, Blake create effect of nursery rhyme, make it sound simplistic, which contributes to his argument that humans take quantity and quality of life for granted, without any thought.
