Answer:
She once was strong, but now she is weak
Step-by-step explanation:
According to the excerpt from Sonnet 11 by Elizabeth Barrett Browning, the poet talks about a girl that claimed Aornus without problems but now she is lying in the valley singing a song of melancholy.
The allusion to Aornus and the description of the speaker's singing voice show readers that she was once strong but now she's weak.
