After winning the Fairy Logician's competition, you are reverse-summoned to a room with 5 portals at equal distances from each other. They are all locked,but fortunately, there is a logical demon in front of each portal, they are willing to unlock one portal for you. The problem is that only 1 of these portals is the exit while the others will send you to your certain death.
The demons are all knowing, but incredibly lazy. They will only allow you to ask 3 questions. They will only provide a 1-bit (yes/no) answer. And if your question requires more than 25 english words* to perfectly grammatically express they won't answer it.
Oh yeah, one more thing, though demons are supposed to lie, all but one of them are to lazy to too that, and will answer truthfully.
Can you get out alive, Logician Adventurer?
(*) words are all you can use, expressions like ∀ε ∃δ have to be expressed like this: "There is a delta for every epsilon", which is 7 words already, and you have 25.
