**Q2 – What was the primary topic of conversation during the first private dinner between Aristotle and Alexander the Great?**  
**Answer:** The dinner was largely devoted to discussing the nature of rulership—that is, what qualities make a good king and how philosophy could guide the conduct of a ruler.  
**Confidence:** 4/10 – The historical record about this very early dinner is fragmentary and largely derived from later biographers (e.g., Plutarch, Diodorus), so the exact subject is uncertain, though most accounts point to discussions of governance and the ideals of a ruler.
