Answer:
The correct answer is option C.
Explanation:
In the poem <em>“When I Heard the Learn’d Astronomer”</em> by <em>Walt Whitman</em>, a person is listening to an Astronomer who is evidently well trained with respect to the scientific subject.
The narrator says that his words seem somewhat <u>useless</u>, and they even bore him.
He seems to be the only person who does not understand the discourse of Astronomy, and feels that <u>just by looking at the sky, he can understand many more things about Astronomy than what can be learned with science</u>.
