Respuesta :
You should post the poem if you want an actual answer, but if I were to guess it'd have to be "to refer to complex life experiences"
Answer:
to refer to complex life experiences
maybe
to compare two kinds of birds
yeah I think the only one that could be possible would be "to refer to complex life experiences" depending on the poem because it's probably the poem about the bird stuck in a cage but if its not then it may be to compare two kinds of birds but if it is that poem about the bird being free and one trapped in the cage then it is to refer to complex life experiences
