Final answer:
The word choice in the excerpt reveals that Crusoe feels isolated and abandoned due to his long period of solitude at sea.
Step-by-step explanation:
The phrase "I dined too, all alone" reveals that Crusoe feels isolated and abandoned. Sailing the open sea for many years without human contact has caused Crusoe to feel lonely and disconnected from civilization. This specific choice of words demonstrates his solitude and emotional state.
In contrast, the other options do not accurately reflect Crusoe's feelings or beliefs. The phrase "sat always at my right hand" does not reveal preoccupation with mastery, but rather highlights Crusoe's companion, his loyal dog. The phrase "no species to multiply" is not about Crusoe's views on lesser cultures, but rather about his inability to propagate and grow a community. Finally, the phrase "grown very old and crazy" is not about Crusoe losing his humanity, but rather about him deteriorating mentally with age.
