Hahaha what is this cursed disease (please LSAT gods, love me)! I also get giddy when I see causal arguments in newspaper articles and I just think, "Hehe, I know what you're trying to do ---but I don't buy it yet!"
The valid argument forms and the existential quantifiers can appear anywhere on the LSAT, not only in particular types of questions. Sure, they may appear more frequently in certain types of questions, but it's not a hard and fast rule.
... argument (S1), a counter argument/arguments or alternate view/ views (A2 ... ), support for the counter argument/arguments (S2/S3) and the author ... support for either of the arguments may vary... and the author ...
It happens, I get caught up when I read random article online that have nothing to do with the LSAT. My brain goes into LSAT mode and I catch myself trying to validate arguments lol
I relate with all four. More so, I have begun to see how illogical I can be as well as how illogical most arguments are (i.e. the ones we are used to hearing on a everyday basis via advertisements, disputes between friends, etc.). Humbling, for sure.
