Is there anyway to figure this question out without LAWGIC???????? I AM STRUGGLING SMMMMMM. #HELP

I wish I was guaranteed there would only be one conclusion!

I slipped up and picked answer D thinking the book contained 2 and not 3. I never thought it could just contain just 1.

So just because PD is sufficient it can be negated????????

Why couldn't it be: if you saw improvements -> mastered logic. I feel like improvements would be sufficient to master logic. Mastering logic would be necessary to see improvements? Why would Mastering logic be sufficient for seeing improvements? aghhhhhhhhhhhhhhhhhhhhhh

So if the key word is in the beginning the x —-> y is backwards……??..? I’m lost on #3 why wouldn’t it be if you’re the highest flying bird of prey you nest in the summits of Andes?

Why is it if you nest in the summits of the Andes you are the highest flying birds of prey? Is it a general rule if the keyword (only) is in the beginning it is going to be backwards ? Pls guide Ty
