Explanation: The statement that cites direct evidence from the passage to support its meaning MOST effectively is Dunbar identifies strongly with a trapped animal: "I know what the caged bird feels, alas!".

His parents were former slaves and he knows what oppressed African-Americans felt. The caged bird is expressing those feelings, which are of profound sorrow.
