There are two persons, one of them always lies, the other always tells truth. How can you find out which one is liying in only one question? Important is that you will have to ask only one question to both of them to find out which one is lying and whcih one is true telling.

Pick one and ask him what the other guy would say if asked!
Edit: I'm really close but that's not quite it - showing my age - thinking back - David Bowie - how does this go - I'll keep working on it...
Edit: O.K. I had to pretend there was a door with certain death behind it yadda yadda...
I was right the first time. (mostly) Pick one and ask him what the other guy would say if asked, "who is the liar?"
Regardless of who is asked the answer is the opposite of whatever answer you are given.
The truthful one if asked what the liar will say will tell you that you will hear he is the liar.
The liar if asked what the truthful one will say will tell you that you will hear the other is the liar.
Either way the opposite of what you are told is correct.
Whew... too much thinking... time for bed!

No, she is not. Blonde guy says "we are all natives". If he is a native, we know this is a lie, if he were a visitor he would not have said that... so he is a native, and there is at least one visitor among the men. Brown-haired guy says "only one of us is a visitor". If he were a native, this would be a lie, meaning more than one of them is a visitor. We know blonde guy is a native, so that would mean there would be two visitors among them (brown and red haired guys). If what he said was a lie, it would mean he was a visitor, which would entail his telling the truth. Therefore, he is telling the truth and he is the only visitor. We know red-haired guy is a native, now, and is therefore lying.

Ask each one separately "are you lying" and watch their eyes to see if they are looking directly at you when they answer and watch their head to see if it's lowered or looking at you directly. Also, see if they twitch their hands or move around uncomfortably. Watch very carefully at all this in the 5 seconds it should take them to answer. More than that and they ARE lying. The truth is an easy and quick answer with no theatrics.

If you are allwed to ask ANY question to BOTH of them, it should be easy to figure out. The trick is to ask only one question to only one of them.
