To determine which inference is best supported by the details in the passage, we need to analyze the statements provided.
- "Harborough feels he is superior to others." - This suggests a sense of pride or arrogance in Harborough's character.
- "The ship's Captain has traveled widely." - This indicates that the captain has experience and possibly knowledge gained through travel.
- "Most people who travel by sea cannot swim." - This implies a contrast between those who travel by sea and their swimming abilities.
- "Harborough grew up in a city." - This might suggest a lack of familiarity with the sea or outdoor activities commonly associated with rural or coastal living.
Given the context, the inference that best aligns with the provided details is that Harborough's feeling of superiority might stem from his urban background and the common perception of those who travel by sea. Therefore, the best-supported inference could be that Harborough believes he is more knowledgeable or cultured than others, particularly those who travel by sea and may lack swimming skills.
Thus, the best-supported inference might be: "Harborough's city upbringing contributes to his sense of superiority over others."
However, the exact wording of the best-supported inference isn’t provided in the question. If there is a particular inference option you would like to have evaluated, please provide it for a more precise answer.
