#1) Which best describes the syntax?
Answer: I believe that they both share the same theme. It conveys the the struggles and limitations of adverse surroundings. In the case of “the caged bird” it is a bird with its wings clipped and his feet tied placed in a cage as it struggles to be free. On the other hand “I know why the caged bird sings” is Mayas struggle in her life during the time of discrimination. Throughout her ordeals she keeps going and develops confidence and the capability to face any struggle.
I hope it helps, Regards.
