Answer:
The narrator decides to keep a journal and writes about her growing dislike for the yellow wallpaper.
Step-by-step explanation:
I feel as though this statement is the rising action since, the first sentence given, "The narrator explains that she doesn't really like the yellow wallpaper in the playroom of the house that her husband has rented," is more like it's part of the exposition. The last statement is more part of the resolution than the rising action.
