Many of the presidents and prime ministers who have had the most successful foreign policies had no prior experience in foreign affairs when they assumed office.
Statements
quantified (many) Many of the leaders with the most successful foreign policies had no prior experience in foreign affairs when they became leader.
conditional (anyone) if you have acute political sense, cool temperament, and can quickly absorb/retain info, then you can quickly learn to have successful foreign policy.
anti-causal (little value) If you lacked all three of these traits, then prior experience alone wouldn't be of much value in terms of your foreign policy abilities.
Evaluate
We had a curious mix of claims. I left out the snarky "although scholars would have us think otherwise", just because it seemed too little like a fact for me to think LSAC would use that.
Is there any overlapping idea?
Foreign policy is mentioned in all three claims. Foreign policy experience is explicitly mentioned in two of them (implicitly it's in all three). Three traits are mentioned in two of them.
It's hard to see an obvious synthesis. If you have the three traits you can be successful, even if you don't have experience. If you don't have the three traits, you might not be successful even if you do have experience.
Goal
Not really sure what we're looking for, so just find the most provable answer choice.
