Another one of those riddles of the two doors but diffrent?

You find yourself in a room with two doors. One leads to paradise, the other to hell. you can choose which door to go though, but the doors are not marked. Each door had a guard, you can ask ONE YES OR NO QUESTION. One guard will always ask truthfully while the other always lies. what question do you ask to ensure your way to paradise?

this is a question my teacher assinged my class. i think she will tell us the answer tomoroww and i i remember, i will tell you. if not, i will let you people ponder this. Good Luck!=)
 
geez this one again?
how many times will people ask this?
the answer is really simple
i figured it out in fifth grade
just ask any guard
"if i asked the other guard which door is paradise, what would he tell me?" then go to the opposite door
if it's the honest one, he'd honestly tell you what the liar would say
if it's not the honest one, he'd tell you a lie
so it works if you go to the opposite door
 
you ask "what door will the other guard tell me?" because the man who tells the truth will tell you that the other man will say whichever door he says which is a lie seeing as he is the liar (though you dont know that) and if you were to ask the man that is lying he will say that the other man will tell you whichever door (but this answer is a lie) So regardless of what they say you always take the opposite door.
