is anyone getting confused about how these transitions to lawgic are working

i think im confusion necessary with sufficient because when I first wrote it out i said:

Authenticity and its desirable for intrinsic qualities → people should buy antique

Here's how I drew out the first question:

Domain: newly arrived cat at Anjellicle Cats Rescue

adoption --> /cat waiting for more than 4 weeks

mittens --> no cats waiting for more than 4 weeks

I find this must clearer than what the video showed, but did I draw it incorrectly?

i thought the translation was supposed to go: Necessary condition → sufficient Condition

why couldnt you negate question 4 and then chain them together

that took me 4 minutes ....i got it right but how the heck is timing supposed to be learned when the answer choices are so long AND so similar

I mapped this out as a conditional

choices made in line with beliefs & choices accepted by others --> easier life

i can see how he made it into a casual chain but did anyone else do this ...

picked A - these explanations confused me more than I was already..

So, confirming a premise or fact in the stimulus wouldn't strengthen the argument (D)
