You go to an island trying to find gold. Every inhabitant is either a knight or a liar. You meet two inhabitants, A and B.

A:Either B is a knight or there is gold on this island.
B:Either A is a liar or there is gold on this island.

What are A and B, and is there gold on the island?

A    and B  can be either KL  LK or KK.  -  there is  gold on the island!  No way LL!
