Hi @Sola, Thanks for the question! So it helps sometimes to rephrase the sentence a little and it’ll make more sense. Is the sentence saying that All babies born with certain instinctive reflexes that disappear by the age of two months are normal full-term babies? No, it’s not, it’s saying the opposite. It’s saying that all normal full-term babies are born with certain instinctive reflexes that disappear by the age of two months. And that’s how you get to NFT —> IR So don’t just blindly see “IR” after “all” and diagram, think about what the “all” is really referring to. Hope this helps! Feel free to ask any other questions that you might have.

I notice that you did not write out the Contrapositive in your analysis of questions A, B, C, or D, but you used the CP to determine the correct answer choice. How is that? How do you decide when to use and when not to use the CP? Please, please advise!
