Problem

What are some trick questions that seem to pose a hard or impossible
question but have a simple answer hidden in an alternate reading of the
wording, and is there a name for them?

P. B. Smith (1996). ]

[ Editor: in reply to the "gry" riddle with the answer "language" (see
language/english/spelling/gry): ]

How unspeakably tedious.  Reminds me of those wretched riddles we used
to pose in grade school:

"'Railroad crossing, look out for the cars!' Can you spell that without
any R's?" "T-H-A-T."

"Constantinople is a very long word, can you spell it?"  "I-T."

And, of course, the nursery rhymes... "There was a woman in our town, silk
an' satin was her gown, silk an' satin, gold an' velvet, guess her name,
three times I've telled it." (Ann).  And "Kits, cats, sacks and wives, how
many were going to St. Ives." (One, the narrator; the kits, cats, sacks
and wives were going the other way).

And the ones that begin "You are a captain" (elevator operator, train
conductor, etc.) At the third stop, two people get on and four get off,
etc.  What color are the captain's eyes?

Is there any name for this class of puzzles--ones that seem to pose a
difficult or impossible question, whose purpose is to misdirect you so
that you don't realize the wording has an alternate reading as a simple
question?  (There are many _adjectives_, such as boring, patronizing,
unsatisfying, obnoxious, etc...)

[ Editor: a later posting by the same contributor, "Ten, nine, eight,
seven, six... and five make eleven." ]

I'm not quite sure what to call this... not a puzzle... but my mother
would "prove" she had eleven fingers by holding out her left hand,
pointing to each finger of her left hand while saying "ten, nine, eight,
seven, six ... " then she would hold up her right hand and say "... and
five make eleven."

Later on, a friend of mine named Bob Blue showed me "another way to
prove it."  He holds up his left hand, counts off the pinky and ring
"one, two, " spreads the hand at that point, and says "hold these three,"
holds up right hand, says, "four, five, six, seven, eight -- plus the
three we held back makes eleven!"

Does anyone have a) a name for this sort of thing, b) more examples?

I dunno if the Abbott and Costello routine ("Can you give me two dimes
for a nickel?"  Abbott does so, realizes he's been had, then Costello
says angrily, "Oh, OK -- HERE's your nickel, GIMME BACK MY TWO DIMES!)
belongs in the same category...

[ Editor: no name for either class was given in the collected
postings. ]

[ Editor: further material on this puzzle, edited separately from other collected postings (batch 12); it may repeat some of the above. ]

[ Editor: problem as stated there: ]
Take two apples from five apples.  How many do you have?  (And other
trick questions of the same kind.)

Here are some examples of what I am looking for.

#1  Q.  Take two apples from five apples.  How many do you have?

#2  Q.  Do they have a Fourth of July in England?

#3  Q.  A plane full of English Tourists flies from Holland to [Editor: "to"
        missing in the original] Spain.
        It crashes in France.  Where should the survivors be buried?

-- Dark Mage <spedge@csd4.csd.uwm.edu> (1993, asking for more)

[ Editor: the parenthetical in the first line is the editor's. ]


#1  A.  You have two apples.

#2  A.  Yes, every country that uses the Gregorian calendar has a
        4th of July.

#3  A.  Survivors aren't dead.

-- Dark Mage <spedge@csd4.csd.uwm.edu>

[ Editor: no further examples were found in the collected postings. ]

[ Editor: question 16 from a list of "tricky puzzles" that Rich
Antcliff found and posted in September 1993: "What was the presidents
name in 1960?" ]

Our present president's name was William Clinton in 1960.  It was not
the name he was born with, but it was changed before 1960.  Viewed in a
different fashion, the president's name in 1960 was either Eisenhower
(the inauguration was in January) or Kennedy.

  Oops, I blew this one.  The inauguration of Kennedy was January 1961.

[ Editor: a reply to Daniel P. B. Smith's question above, "Is there any
  name for this class of puzzles?": ]

since no native english speaker found it worthwhile to answer, perhaps
i can try:

trick questions? :)

I'm surprised this old chestnut got so far.  (On my server, I've seen
two incorrect answers and no correct ones.)  Any votes on putting it
into the rec.puzzles archive if it's not already there?

ANSWER--The odds are zero, since 72 hours later, it is midnight on July
7, 1995.  (Some might argue that the odds are *very close* to zero,
since we do have one recorded instance in the Bible of the Earth's
rotation stopping to provide additional daylight during a battle.)

Except 12pm isn't midnight, it's noon.  If today is Tuesday,
yesterday's 12 pm is noon on Monday, and tomorrow's 12am is the start
of Wednesday.  The correct answer is 36 hours.

I'd have to go with the French.  They have such great food!  And
fashion!  And art!  And a different numbering system!  (One billion
English/German/French = one trillion American)

It depends what definition of 'put' you use, but there's either 1 or
75.  Or 0, considering they're washed away now, and you didn't _have_
them to begin with, just built them.
