bumping this because I think this is super important! The difference between causation and conditionality has always been a bit fuzzy for me but @"Accounts Playable" you made the distinction super clear! Thank you!
@"Accounts Playable" Yes. I would treat "it is a given" and "for such" as premise indicators. "Given" would introduce evidence (premise) for a conclusion. Treat "for such" the same as you would "for".
Accounts playable is right, most of the causation weaken/strengthening questions that i have come across draw some correlation between two things and then make a casual conclusion that you either need to best weaken or best strengthen.
