    • Four Martians from different groups, the Uti,
      Grundi, Yomi and Rafi, gathered for an intraplanetary
      conference to discuss the problem of the visiting Earthlings.
      As was appropriate for diplomatic envoys, all
      were beautifully feathered in different colors, one red,
      one green, one blue and the fourth brown. Their names
      were Aken, Bal, Mun and Wora.
      1. Before the meeting, the Uti had a pleasant breakfast
      with Mun.
      2. After debating with the Martians in the blue and
      the brown feathers, Bal and the Yomi were so angry
      that they tore a wingful of feathers out of them
      before they were stopped.
      3. Wora and the Rafi, however, agreed with the diplomat
      with brown feathers, though they disagreed
      with the red-feathered Grundi.
      Who is the blue-feathered diplomat and to what
      group does he or she belong?

    • Kim Jones, Jan Robinson and Pat Smith are the officers
      of the spaceship. They serve as the craft’s pilot,
      engineer and biochemist, though not necessarily in that
      order. Because they have difficulty with Martian names,
      they nickname the three Martians who work with them
      Jones, Smith and Robinson.
      1. Robinson is a Yomi.
      2. Jones doesn’t speak any language other than
      Martian.
      3. Most Martian linguists are Uti.
      4. The Martian who serves as interpreter respects the
      Martian whose name is the same as the biochemist’s.
      5. The Martian whose name is the same as the biochemist
      is a Grundi.
      6. Jan Robinson beat the engineer at chess.
      Who is the pilot?

    • Martians don’t need to develop airplanes as a means
      of moving through the air. Most feathered Martians can
      fly easily. Every few lunars, feathered Martians from
      the various groups participate in a tournament to determine
      which are the best fliers of the planet.
      This lunar, teams of two feathered Martians from
      three groups are competing:
      1. One team is from the Uti, one from the Grundi,
      and one from the Yomi.
      2. Each team is made up of one female and one male.
      3. The female participants are Xera, Wora, and Teta.
      4. The males are called Vel, Pyi, and Rir.
      5. Despite her daring feats in the air, Teta had never
      been away from home before the contest.
      6. Xera and Rir had never met before the tournament.
      7. Xera will be visiting Pyi’s group when the Yomi go
      on a special excursion to that part of the planet.
      8. Pyi admires Teta’s colorful feathers, as well as her
      ability to soar, and once watched her and her teammate
      in the territory of the Grundi.
      If the winners are members of the Uti group, what
      are the names of the best fliers?

    • Hostile members of the Uti, Grundi and Yomi groups
      were travelling to a conference. There were two members
      from each group, one finned and one feathered.
      The finned Martian was much stronger, and had to
      protect her feathered friend. Never could a feathered
      Martian be left alone with a finned Martian of another
      group. The only time a feathered Martian was safe with
      the finned Martian of another group was when the
      feathered Martian of that enemy group was also
      present.
      The trip was quiet until they came to a deep ravine.
      The only way to cross it was by swinging across on a
      rope. But the rope was only strong enough to hold two
      of them. And it wasn’t heavy enough for them to swing
      it back over the ravine without someone to weigh it
      down. How did they all cross the ravine?

    • Harassed during important experiments, three Earthlings
      were taking three law-breaking Grundi to the authorities.
      Suddenly they heard the thunderous roar of a
      rockfall, and they knew they were facing sure death
      unless they crossed to the other side of the canal. The
      portable watercraft they carried with them would hold
      only two passengers, regardless of weight. At no time
      could there be more Grundi on either side of the water
      than Earthlings or the Grundi would overpower the
      Earthlings. How could they all cross the water safely

    • 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?
