Final answer:
Both 'The Caged Bird' and 'I Know Why the Caged Bird Sings' share the same author, Maya Angelou, and both address themes of confinement and freedom related to the experiences of African Americans.
Step-by-step explanation:
Both “The Caged Bird” and “I Know Why the Caged Bird Sings” share the same author, Maya Angelou. “The Caged Bird” is Angelou's famous poem that metaphorically describes the experiences of African Americans through the symbol of a bird struggling for freedom, while “I Know Why the Caged Bird Sings” is her critically acclaimed autobiographical novel that details the early years of her life and similarly tackles themes of racial discrimination and personal liberation. Despite having different forms, one being a poem and the other a novel, they both explore themes of confinement and freedom and resonate with the struggles that black Americans endured, reflecting Angelou's powerful voice in the fight for civil rights.
