Here's a one-question IQ Test

[Captain Kremmen]

I don't fall for these anymore. Something about getting older and wiser, and having seen so many variations before.

I must be old and stupid.
My answer was: "He writes it down", still imagining that he couldn't speak or hear.

[Captain Kremmen]

I got the answer in ten seconds flat. Here's a traditional one for you:

As I was going to St Ives
I met a man with seven wives
Every wife had seven sacks
Every sack had seven cats
Every cat had seven kits
Kits, cats, sacks, wives.
How many were going to St Ives?

The answer "one", is inaccurate.
The answer to this is "At least one".
There may have been other people going to Saint Ives,
but the rhyme does not give that information.

I met a man with seven wives
Every wife had seven sacks
Every sack had seven cats
Every cat had seven kits
Kits, cats, sacks, wives.
How many were going to St Ives?

The verse doesn't actually say which way "the man" was going nor does it say for sure how many, if any, of his wives were with him. It's possible, for example, that the man was sitting by the side of the road and he told the narrator about his rather unusual family. The best answer we can give is that "at least one" was going to St. Ives.

Good Point.
There may have been as few as one person the poet met on the road to St Ives.
The man had seven wives, but they may not have been with him.
In fact, they probably weren't.
Who would bring all those wives, sacks and cats etc on a journey?
