RC Function Questions

--skim--

When it asks about the primary function of a specific paragraph, should we pick the answer that connects it back to the whole psg/MP or the answer that relates it to one part (like the paragraph at hand is meant to exemplify the last sentence of the previous paragraph or something like that but that in turn is meant to support the MP)?

And when it asks about the primary function of a specific word or line, should we pick the answer that connects it back to its role in the paragraph it's in or the answer that relates back to the whole psg/MP?

Also is there a difference in the approach if it asks about the "primary function" versus "function?"

I'm finding myself taking a bit longer and getting these function questions wrong and would appreciate any insight or method that helped you!
