I'm going to try to paraphrase this to make sure I am tracking this concept:

You take the premises from the conditional conclusion and move them up to the earlier group of sufficient conditions (other premises). This technique helps isolate a conclusion to be an unconditional statement, thus making it easier to identify the missing rule that would make the argument valid.

......yay or nay?

I understand that one of two sufficient conditions is enough to fulfill the necessary condition, but I am struggling to understand how two conditional claims in the necessary condition with one sufficient condition create a valid argument? Any insight team?

Very helpful to remember the indicators for both necessary and sufficient conditions. Additionally, it's important to remember that the sufficient condition should trigger the necessary condition for a valid argument. (Please correct me if I am wrong about the latter!)

Struggling with understanding answer choices that say "takes for granted". Does anyone have a way they rephrase this to themselves?
