    Hello! My home-schooled teenage sons and I are enjoying the logic class. We are wondering about one of the exercises, though, since we all got a different answer than you. It is the Exercises in Construction set, number 5. We obverted the second premise to get NAR, as you did. But in your answer you said that neither premise distributes the middle term (Rule 5), thus there was no valid conclusion. Isn’t the middle term (N) distributed in NAR because it’s an “A” type? Are we missing something? Thanks!
