는지 알아보다

look into what, find out whether

An embedded question with "-는지" under 알아보다, "look into, find out, check". It is the phrase for going and finding out something you don't yet know: find out when the concert is, look into whether you can get this support, check how much they actually pay, find out what the results were. Compare 알다 "already know" — 알아보다 is the checking itself, which is why so many of these lines end in 싶고, 봐야겠어, 보도록 합시다: they are intentions to go and look.
