Question

how do metaphors and extended metaphors differ?
while a metaphor is limited in length, an extended metaphor is developed over the course of a poem.
while a metaphor describes the way someone thinks or feels, an extended metaphor compares multiple unlike things.
while a metaphor conveys a set of ideas, an extended metaphor conveys a single idea across the poem.
while a metaphor makes a comparison, an extended metaphor shows the attitude of a text toward its subject.

Explanation:

A standard metaphor is a short, direct comparison between two unlike things, while an extended metaphor expands this comparison and develops it across a longer text (like a poem, paragraph, or entire work). The other options are incorrect: standard metaphors can describe thoughts/feelings or make comparisons, but extended metaphors are defined by their sustained development, not comparing multiple things, conveying a single idea, or showing attitude.

Answer:

A. While a metaphor is limited in length, an extended metaphor is developed over the course of a poem.
