C. An individual's place in the world is determined by his or her environment.
Explanation:
Dunbar describes what is it like being a black male in the 1800s America in his poem Sympathy. He gives a metaphor to the caged bird and how deadly the bird wants to get out after it sees a beautiful landscape.
Stephen Crane's A Man Said to the Universe shows the significance of the existence. And this is the existence of a human-being. This human-being is an individual and the poem is about his conversation with the universe. The man wants a recognition from the universe.
The summaries show that the correct answer is the third one - an individual’s place in the world is determined by his or her environment. Indeed, in both poems individual challenging is present.
The correct answer is "her". This is because an antecedent basically means to whom does the pronoun refer and the pronoun has to refer to Miss Kensington. This is why the correct form is her.
