I don't understand this one either - can you please help?

I realized that I was rushing to answer some of the questions, limiting my thinking ability. As a result, I missed the logical structure of the answers. For instance, the question refers to the Labrador Retriever barking. During my review, I missed the logical answer because of the way it was presented. I confused myself greatly.

Also, I need to come to understand the simplification or how LSATmax breaks down a question. I dove into this drill too soon.

For these definitely start by writing out the contrapositives, so we have

Not A -> B (Not B -> A)
A -> not Z (Z -> Not A)
Not Z -> F (Not F -> Z)

To find a conclusion, we can pick any of these statements and just link it onto the others. Let's pick A-> Not Z. Well we also know Not B-> A, so we can link these as
Not B -> A -> Not Z. And we know Not Z -> F, so we can add that and get
Not B-> A -> Not Z -> F.

Simplify to get Not B -> F, or the contrapositive Not F -> B. Hope this helps!

Thank you, Jay, you have helped me greatly your answer reinforces what I found in my notes. I have come to rely on note-taking, especially the explanation the instructors give in the Q&A sections. as we say in HI Mahalo.

This is my first day studying. The explanation/ break down you shared Jay i still don't understand. did i jump into the drills to quickly?

I don't think you jumped into them too quickly. The drills take time to master. Stay patient, and you'll eventually get there!
