"O" should be placed in the center.
Let's number the positions as:
1 | 2 | 3
---------
4 | 5 | 6
---------
7 | 8 | 9
It is given that "X" is placed in one of the corner
position. Let's assume that its at position 1.
Now, let's take each position one by one.
? If "O" is placed in position 2, "X" can always win by
choosing position 4, 5 or 7.
? If "O" is placed in position 3, "X" can always win by
choosing position 4, 7 or 9.
? If "O" is placed in position 4, "X" can always win by
choosing position 2, 3 or 5.
? If "O" is placed in position 6, "X" can always win by
choosing position 3, 5 or 7.
? If "O" is placed in position 7, "X" can always win by
choosing position 2, 3 or 9.
? If "O" is placed in position 8, "X" can always win by
choosing position 3, 5 or 7.
? If "O" is placed in position 9, "X" can always win by
choosing position 3, or 7.
If "O" is placed in position 5 i.e. center position, "X"
can't win unless "O" does something foolish ;))
Hence, "O" should be placed in the center.

However, all of the inhabitants are either Fairies or Trolls and they all use a spell to appear humanoid so you cannot tell which is which. And the Faries always tell the truth and the Trolls always lie, but there is a slight complication, some of the Fairies have gone insane and always lie and some of the Trolls have also gone insane and always tell the truth. So here is your task: you must ask the first inhabitant that you come to ONE question and from that ONE question you must determine wether Atlantis is still around or not. What is the question that you must ask?
