Sorry no clue this is more of a science question.
The informative essay structure is a introduction, body and conclusion. It’s used facts and a logical way to organize your facts as well.
When I read a story with a dialogue, I start to get an understanding on what the plot of the story may be. Foreshadowing is also something that happens in dialogues that you must pay attention to, it gives you clues.
Also, sometimes if a paragraph is long, the reader can get thrown-away from the story or get bored. So a dialogue may interest the reader again.
I hope this helps!
