Final answer:
In Henrik Ibsen's play 'A Doll's House', the nurse is best compared to the role of a mother, as she fulfills a nurturing and caring role for the children, similar to what would be expected of a mother figure in a traditional household.
Step-by-step explanation:
The dialogue you mentioned is from Henrik Ibsen's play "A Doll's House", where the character Nora questions the nurse about leaving her child. In this context, Newton isn't the subject of the question; rather, it seems to be a reference to the nurse character in Ibsen's play. Considering the given dialogue and general thematic elements of the play, the nurse's role is often compared to that of a mother figure - one who cares for and nurtures children. This is because the nurse, like a mother, is usually the primary figure of nurture and support for the children in a traditional household. It's important to note that, in literature, different readers might draw different comparisons or interpretations depending on their perspective.
