Passage Summary: You don't need experience to be good at foreign policy if you're smart and disciplined; in fact, experience doesn't help much if you lack those qualities.

Reasoning: Many successful leaders had no prior foreign policy experience; foreign policy can be learned quickly by those with political sense, discipline, and information retention; experience is useless without these three traits.

Analysis: Treat the premises as absolute facts to see what must follow. The text establishes that three specific traits are sufficient for learning foreign policy and that experience is insufficient without them. We should look for an answer that logically follows from these rules, perhaps noting that a successful leader without experience must possess those three traits. Avoid any choice that introduces new requirements or makes absolute claims about experience being 'never' useful.
