You start to see in it premonitions of her suicide. as the title suggests being on the edge or having slipped off. the poem is about a" perfected woman" one who starts the read it as the poem about plath herself dead, perfect. the central figure then becomes the woman Plath thought she would become by her suicide, with a relief,and the defiance all the encompassing knowledge " she's used to this sort of thing" she then would possess as well as her frightening qualities. ( blacks crackle and drag). that in her Superior way she can take for granted although we as readers cannot I hope I get a brainiest answer on this cuz this is a really good answer to your question
I read this story and so I can say its answer should be 4 (She has gained a deeper understanding of her daughter).
If there is a selection of answers I would go with
Repetition
Parallelism
maybe some others but I don't know all the poetic devices you have to chose from
Maybe their all watching T.V?
