^They all make right turns!
One of spies A and B always tell the truth while the other may say anything. They are sent to investigate statements W,X,Y, and Z, and making the following reports:
Spy A says:
Exactly two of W,X and Y are true
Exactly two of X,Y, and Z are true
Exactly one of W and Z is false
Spy B says
Exactly two of W,X and Y are true
Exactly two of X,Y, and Z are true
Exactly two of W,Y, and Z are true
Determine which spy tells only the truth, and which assertions are true.
