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:

To determine the correct answer, we analyze each option:

• Option A: A metaphor is a single comparison, while an extended metaphor is developed (e.g., across a poem, with more details/verses expanding on it). This matches the typical definitions.
• Option B: Metaphors can compare multiple unlike things (e.g., "life is a journey" can have multiple aspects), so this is incorrect.
• Option C: An extended metaphor usually develops a single idea more deeply, but a regular metaphor can also convey a set of ideas (or a single idea). The description here is reversed, so incorrect.
• Option D: A metaphor makes a comparison, but an extended metaphor is still a comparison (just extended), not about showing attitude (that's tone or other elements). So incorrect.

Answer:

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