Question

the most important distinction between most poetry and all types of prose is:

1. Rhyme
2. Meter
3. Line Length
4. Cadence

Answer 1

It is either meter or line length. Poems are "spoken" in (usually) short sentence fragments or phrases while prose is more formal and grammatically correct and composed of complete sentences.

Answer 2

Thanks you :)

Answer 3

You're welcome... my top guess is line length though. Hope this helps!
