Amanda wishes to be a mermaid so that she could drift slowly on a languid emerald sea. She longs for a life of complete solitude and silence, away from the constant instructions and nagging she faces. As a mermaid, she would be the only occupant of the shining sea, moving carelessly and freely, with no one to scold or restrict her. This represents her deep desire for freedom, peace, and escape from the pressures of her daily life.
The question is from the poem Amanda! by Robin Klein. The examiner expects three points: (1) what Amanda imagines as a mermaid, (2) why she wants that life (solitude/freedom), and (3) linking it to the nagging/restrictions she faces at home. Even though the source passages provided don't contain this poem, this is a standard textbook question from First Flight, Chapter 6. Always connect Amanda's fantasy to the theme of escapism caused by constant parental instructions.
