Step-by-step explanation:
The structure of the myth "Welcome to the Underworld" and the poem "Psalm of Life" differ in several ways, and the best description of how these texts differ in structure is option (b): The myth's cause/effect structure is meant to give the audience a warning; the poem uses metaphors to provide the audience with advice. This is because myths tend to follow a narrative structure that includes a plot with a specific sequencing of events leading to certain outcomes, often in a cause-and-effect manner, which can serve to relay a moral or cautionary lesson. On the other hand, the poem "Psalm of Life" likely utilizes poetic devices such as meter, rhyme, and figurative language, including metaphors, to convey its themes and provide insight or advice to the reader. Poems often rely on the artistic arrangement of stanzas and lines to convey deeper meanings and engage the reader emotionally, whereas myths are structured more for storytelling and imparting cultural values or warnings.
