For question 6, I had answered it like this:

I kicked cooperative farms up to the domain.

Then, since but on the LSAT implies '"and", I had my Lawgic form like this:

Domain: Cooperative farms

/direct Tyrell control and under Tyrell influence --m--> pay tax.

Can this be done or am I mixing conditional logic into this too much?

I swear this is super important. I was looking at some LSAT questions before I started my prep and some of them I'd read and my brain would go like nope. I'd have to slowly go over it and dissect the sentence so my mind can digest the information it offers, which wastes a lot of time!! Knowing that the LSAT puts test takers under a strict time limit, saving the extra seconds or even minutes that understanding some sentences takes can be helpful.

Human communication is a universal phenomenon that has existed across different civilizations over time. Linguists have conducted many comparative analyses of traditional languages from various regions and eras.

Can someone please explain why this isn't an argument? I can't wrap my head around it. Thanks in advance!!
