    • Two Martians and two Earthlings traveling together
      came to a canal. As a result of the gravity on Mars, the
      Earthlings each weighed 100 pounds and the Martians
      fifty pounds. The watercraft would hold no more than
      100 pounds. How did they all cross the canal?

    • Jonathan Mark gathered three specimens of Martian
      plant and animal life to bring back to Earth: a garble, a
      farfel and a tsientsien. But Mark was worried. His vehicle
      for local travel was not big enough to hold more than
      himself and one specimen. Mark knew that garbles will
      eat farfels if given half a chance, and farfels will eat
      tsientsien. Garbles, however, don’t eat tsientsien, and
      tsientsien don’t eat. All the other astronauts were away
      from the ship. How could Mark transport the garble,
      the farfel and the tsientsien one at a time so that they
      would all be safe?

    • There was trouble from the Grundi. One of them
      damaged the spaceship by hurling a rock at it. The
      astronauts couldn’t figure out what the Grundi had to
      gain by their hostile act. Was it just vandalism, done out
      of sheer spite? Or perhaps not everyone on Mars was
      happy to see the Earthlings return.
      The Martian police chief brought in five Grundi for
      questioning. Like all Grundi, they sometimes told the
      truth and sometimes lied. The suspects each made
      three statements, two of which were true and one of
      which was false. And the guilty one was revealed.
      1. Zum said:
      I am innocent.
      I have never used a rock to destroy anything.
      Tset did it.
      2. Uk said:
      I did not do the damage.
      The Earthman’s vehicle is on Grundi space.
      Yan is not my friend.
      3. Pala said:
      I am innocent.
      I never saw Yan before.
      Tset is guilty.
      4. Tset said:
      I did not throw the rock.
      Yan did it.
      Zum did not tell the truth when he said I did it.
      5. Yan said:
      I am innocent.
      Uk is guilty.
      Pala and I are old friends.
      Who was the culprit?

    • This was astronaut Jose Perez’s fourth visit to Mars
      and he had learned to speak Martian. He wanted to
      find his Martian friend Doman, but in order to locate
      him he had to know what group Doman belonged to.
      The three groups in the area were: Uti, Yomi, and
      Grundi.
      The Uti always told the truth.
      The Yomi always lied.
      The Grundi sometimes told the truth but sometimes
      lied.
      Perez needed information. Three Martians, Aken, Bal
      and Cwos, each of whom belonged to a different group,
      agreed to help him. He asked each one of them two
      questions: What group do you belong to? What group
      does Doman belong to?
      1. Aken said:
      I am not a Uti.
      Doman is a Yomi.
      2. Bal said:
      I am not a Yomi.
      Doman is a Grundi.
      3. Cwos said:
      I am not a Grundi.
      Doman is a Uti.
      What group does Doman belong to?
