Explanation

Hey Madelyn, I'm not with LSATmax but A is correct because if you negate the argument would break. If it is true that "Examining an individual leader's personal flaws can reveal anything about how the nation's institutions and procedures influence the selection of leaders" then it is not pointless to focus on the leaders -- you'll be learning about the institutions and so will be fulfilling one of the premises. Hope this helps!

@Madelyn-Luskey, @Kanyin is correct. This question is a strengthen with a necessary premise question, so if the negation of an answer choice wrecks the argument, then we know that it's the correct answer choice. Does this make sense? If you'd like further clarification, let us know, and we'll be happy to help. @Kanyin, great participation. Keep up the hard work, and thanks for engaging with your fellow students on the boards!
