Who do you think is speaking to her?
It is Amanda's mother (or a parent) who is speaking to her. The speaker is constantly giving instructions and reprimanding Amanda for her habits and behaviour, such as biting her nails, hunching her shoulders, and not finishing her homework.
The speaker's tone is nagging and authoritative, asking questions like "Did you finish your homework, Amanda?" and "Did you tidy your room, Amanda?". This reflects a typical parent-child dynamic where the parent is trying to discipline the child.
The speaker also accuses Amanda of sulking and being moody, saying, "Stop that sulking at once, Amanda!" and "Anyone would think that I nagged at you". This further confirms that the speaker is an elder or parent figure who is constantly correcting Amanda.
Explanation
The question asks to identify the speaker addressing Amanda in the poem. The context shows the speaker giving a series of commands and instructions (e.g., 'Don't bite your nails', 'Stop that slouching'), which is characteristic of a parent scolding a child. The speaker also expresses frustration that Amanda might think she is being nagged, a common sentiment in parent-child relationships. Therefore, the speaker is Amanda's mother or a parent.
