Answer:
While a metaphor is limited in length, an extended metaphor is developed over the course of a poem.
Explanation:
This is the correct explanation of how metaphors and extended metaphors differ. A metaphor is a figure of speech that directly refers to one thing by mentioning another. Metaphors serve several purposes, but they are usually used in order to provide clarity. An extended metaphor fulfills the same role. However, this is "extended" because it is developed over the course of a whole poem.
