I finished all the questions following the same logical reasoning in every card, trying to build the big relationship between all the letters. If the conclusion is "Not A ->D", I put "Not A" on the beginning and "D" on the end and fulfill the blank space using the positives and contrapositives of the premise and conclusion that are given (sometimes just the positives, sometimes just the contrapositives and sometimes both).

Besides I am getting must of the answers right, I am missing the ones that the correct answer is the contrapositive of the what I found. I tried to establish a standard between the cards and answers, but I couldn’t find it. I feel like the answer of some questions that requires the same logic sometimes will be the positive of what it’s found, sometimes the contrapositive.

Can someone please explain to me how do I know when to use the contrapositive of the answer that I found after create the big relationship following the conclusion as it’s given and when to use the positive?

Thanks!!

Hello @Augusto,

I responded to another of your questions with a similar answer, but I will respond briefly here as well.

In short, if you find the contrapositive of the given correct answer, then you can consider it correct. A contrapositive and its original statement carry the exact same logic, so don't worry if you write one instead of the other.
