Question

you're trapped in a room with two doors. One leads to certain death the other leads to freedom. You don't know which is which. There are two robots guarding the doors. They will let you choose one door but upon doing so you must go through it. You can, however, ask one robot a question. The problem is one robot always tells the truth, the other always lies and you don't know which is which. What's your question?

Answer 1

Ask one which door the liar would tell you to go through. If their response has I in it they are the liar and so you should go to the other door. If their response says the other would say they are the truth teller so go through that door. Hope this helps! :) :D

Answer 2

Ask one of the guards which door would the truth telling guard point to and if you asked the truth guard it would say I would point you to that door
 and is you asked the liar then it would say the truth telling guard....
hope this is right
