   How many tests that are black in color are entirely   
   white in color and the answer must be a positive   
   integer and must come with proof that it is correct.

   Is this sentence true or false: "This sentence is not true" ?   
   The above is the basis for the Tarski undefinability theorem.   
      
   What correct value can a halt decider return on an input   
   that does the opposite of whatever the halt decider decides?
