Which traveler seems to know the most about physical illnesses?

• A. John
• B. Noah
• C. Casy
• D. Tom

Answer: (C)

Understanding who seems most knowledgeable about physical illnesses comes from seeing which traveler consistently encounters sickness and offers practical care. Casy, traveling with the group, spends a lot of time with people who are sick or suffering. His role as a caregiver and his calm, pragmatic approach to illness come from these repeated, real-world encounters along the road. That broad exposure to different ailments and the ability to comfort and assist others signals a deeper familiarity with physical illnesses than the others, who are defined more by labor, youth, or spiritual guidance rather than hands-on care. So, Casy stands out as the traveler who seems to know the most about physical illnesses.
