Brain Teasers
World Cup
An alien spaceship landed on Earth. They knew that earthlings are divided into three groups: those who always tell the truth, those who always lie, and those who do both, alternating between true and false statements, starting with either.
"Let's go!" said the alien captain.
The aliens approached three earthlings, who each were from a different group, and asked, "Who won the last World Cup? Who came in second? Who came in third?"
One of them responded, "Zaire first. Uruguay second. Spain third."
Another one said, "Zaire first. Spain second. Uruguay third."
The third one said, "Uruguay first. Spain second. Zaire third."
The aliens returned to their spaceship and flew back to where they came from. Do you know which response was the true ranking in the World Cup?
