  • Meanwhile, back at the castle, the ogre found that the

    territory.
    If in that dark storeroom he had four six-league boots
    and eight seven-league boots, how many boots did he
    have to pull out to make sure he had a pair of sevenleague
    boots?

  • The king had his doubts about his sons’ fighting
    skills, and so he sent his two eldest to the court magidan
    for potions to help fight the ogre.
    The magician kept his magic hidden, mindful of the
    danger of his potent potion falling into the wrong
    hands. In a secret but inconvenient compartment in his
    laboratory, he hoarded:
    1. four ogre-fighters
    2. three dragon-destroyers
    3. two evil wizard-vanquishers
    How many potions did he have to reach for in order
    to make sure that he could give an ogre-fighter to each
    of the king’s two sons?

  • 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?
