Pregunta 6:
Te cruzas con dos habitantes de la isla (la misma isla de las preguntas anteriores), Nathaniel y Hans. Tu le preguntas a cada uno si el otro es caballero, y ambos te dan una respuesta de “si” o “no”.
Si ambos contestan “si”, entonces que puedes decir acerca de ellos?
La primera persona que escriba un comentario con la respuesta correcta se gana una copia de Cycles Comic Book.
Either they are both knights, or they are both knaves. If they had both answered “no”, then one must
be a knight and the other a knave. Since there is no other possible combination, it is impossible for
one to say “yes” and the other “no”.
Maybe I’m not the only one with a strategy…
They are either both knights or both knaves, but they cannot be one of each.
Ok, I’ll bite on this one since I’ll be at church when Perla asks question 9 and Abbi snatches up the DVD.
Either they are both knights or they are both knaves.
If they are both knights, ask either one whether the other is a knight and he truthfully answers yes.
If they are both knaves, ask either one whether the other is a knave and he falsely answers yes.
If one is a knight and the other a knave, the knight would have to be lying to affirm that the knave was a knight.
If they are both knaves, ask either one whether the other is a knight and he falsely answers yes.
Hello:
All are right, but Josh Cason answered first, so he is the winner, Congratulation! So see you Josh n question 10.
