<u>Explanation:</u>
The author Ray Bradbury showcases Montag as a protagonist character who is troubled with the world around him. He feels he has a responsibility to change how people behave in society, such as facilitating a love for nature among them.
For example, we recall his encounter with Clarisse McClellan, a young woman he met in his neighborhood whose views about nature greatly influenced him, compelling him to be more conscious of nature, wanting to change society.
His troubled emotional state is made evident even further as we observe how he struggles to understand himself, his motivations for doing things which even led him to kill Beatty.
The definition of the antecedent of a sentence is that if a word refers to a previous noun or pronoun in the sentence, that pronoun or noun is its antecedent. Let's eliminate some options. Looked is a verb so it cannot be. All around the room is a general space qualifier and thus this is irrelevant too (it does not refer to Samuel's room for example). Now we find the relevant part, "his shoes". The pronoun is his. Hence, we have that the antecedent is Samuel.
