Which is NOT one of the differences between literary works and dramatic works?

The lack of dialogue is not one of the differences between literary works and dramatic works. Both literary works and dramatic works can contain dialogue and play with language. Other differences between the two include the use of visual and auditory elements in dramatic works, the presence of stage directions and the need for actors, sets, and costumes in dramatic works, and the performative nature of dramatic works compared to the solitary act of reading literary works.
