	The question : " If I ask the other witch the way to Oz, 
			 which would she lead me to? "


        You can bet your a*s that the answer would be directed to dev/null.
	So take the other path.

	Reasoning : case 1. The question was asked to the truthful witch-
	 
        She knows her co-witch is an inveterate liar, and would show Dorothy

	the way to dev/null. 

		    case 2. The question was directed to the deceitful one-

	She knows her partner is truthful and would show Dorothy the right

	way to Oz. But she being a liar wouldn't tell her that. So she too

	shows the way to dev/null. 


	So all Dorothy has to do is complement the path.
