Answer :
Poole's distressed appearance influences Mr. Utterson's perception and response, exemplifying the theme that appearances shape opinions.
The excerpt from The Strange Case of Dr. Jekyll and Mr. Hyde best connects to the theme "Appearances shape people’s opinions" through the choice: Poole looks so disturbed that Mr. Utterson listens to him closely. Poole's obviously shaken appearance and altered behavior provoke a serious response from Mr. Utterson, who begins to believe that something distressing and potentially sinister is happening. This interaction demonstrates how someone's outward appearance can influence the perception and reactions of others, aligning with the theme indicated in the question.
