Im having so much trouble properly mapping these things out. My map always looks different which ultimately messes up the answer I choose, any tips?

I feel like I always get majority but miss a couple in each phrase, does anybody have any tips on that?

So if an assumption is arbitrary, should I bump it up to a premise to make it stronger? And why would I do that. Wouldn't it just make it a weak argument?

Do you just pull assumptions out of thin air? It feels very subjective

Would this mean that basically every thing is an assumption?
