How is a prose different from a verse?

The main difference between prose and verse is that prose is written naturally whereas verse is written in metrical structure; Prose refers to the language in its original and natural form whereas verse refers to the language used in poetry.
Hope this helps c:

A verse typically has some sort of rhyme scheme, and in metrical rhythm. A prose is written in its ordinary form, without metrical rhythm. 

D. Judy told her roommate, “I’ll arrive early for my first riding class. I’m so excited!” is the correct punctuation, I believe.
