    \item **A1:** The third person to walk on the Moon was Pete Conrad, commander of Apollo 12 (November 1969). This followed Neil Armstrong (first) and Buzz Aldrin (second) from Apollo 11.  
    **Confidence:** 9/10. While widely accepted, minor ambiguity exists due to mission order debates, but Apollo 12 is well-documented.
    
    \item **A2:** There is no historical record of the specific topics discussed during their first private dinner. However, plausible conjectures include philosophy, ethics, leadership, or Aristotle’s teachings on governance and virtue, given his role as Alexander’s tutor.  
    **Confidence:** 3/10. Highly speculative, as no direct accounts survive from antiquity.
