What makes poetry unique among other genres of literature

It is more metaphorical

Explanation:

You have to be really creative to write a poem.

It is unique since it has a more deeper meaning compared to other stories.

While a few poems are really hard to understand,they are sometimes interesting

Shakespeare's Merchant of Venice has many references which makes it more interesting

There is a wide usage of alliteration , metaphor and other figure of speech which makes it unique

There might be metaphors even in stories but in poetry,they are more in number

the answer is both an appeal to ethos and logos (if that's what your question options were)
