The following two facts are known about Adam, Bert, and Carl:

1) Of Adam, Bert, and Carl, there is one knight, one knave, and one liar.
2) Adam said once, "Bert said that Carl isn't a knight."

Can you ask one yes/no question to one person and figure out who is who? If not, how many questions must you ask?

(In reply to re(2): Two Questions by Liam)

 Ok theres a way for one question solution, Adam said bert had said carl isn't a knight therefore bert must be the liar,carl the knight,and Adam the knave so there fore youd simply need to ask if ur answer is right
