For Necessary Assumption, are you finding the assumption to figure out what's required for the conclusion to follow and what the argument depends on? Also, for weaken questions we usually try to find an alt. hypothesis to weaken the argument, and for strengthening questions we try to eliminate any alternative hypothesis. How does this framework play a role in Nec. Assumption Q's?

every time i think i'm getting the hang of LR, i get quickly humbled

does anyone else SEVERELY struggle with strengthen questions or is it just me...
