The answers with their sub parts are given down below:
Explanation:
1. a. The author uses irony to  show the hilarity of the situation of the narrator. This creates surprise  because it is not to be easily believed that they could be in a dream state.
2 a. Maupassant develops the narrator by  reading into their thoughts around bizarre situations.
Over the course of the story, this shows the  character's  and the disputation's obscurity.
3. The scale of things around the narrator has drastically changed and there is no sense of how big or small certain things must be. This helps illustrate the narrator's  compromised judgement by getting into their mind.
4. I think it was a dream because it explains away the imagination of the character.
5 a. The narrator is better off  not knowing what he discovers in the end because they had learnt more from the ambiguity of the situation than by knowing of it.
