To accurately answer your question, I would need to read the specific excerpt you're referring to. However, based on the options provided, if the dialogue and descriptions highlight contrasting behaviors and attitudes between Hueng Bu and Nol Bu, I can suggest that the best choice might be:
"It shows that Hueng Bu takes time to enjoy life but that Nol Bu focuses on work and doing better than his brother."
This option indicates a difference in perspective and priorities between the two characters, which dialogue and descriptions often reveal. If this aligns with the themes and character actions in your excerpt, it may be the best choice. If you can provide more context or details from the excerpt, I might be able to give a more nuanced answer!
