I often wondered why simple CAPTCHA's like "Type the number seven
four three", or "What is the sum of two plus three?", or "Spell cat",
or "Spell two" wouldn't work? Certainly, one can create a routine
coupled a dB to randomly produce thousands of different combinations
of simple questions. Likewise, a sound file could be produced the
same way.
This could get hard for people, not everybody does understand a lot of
English. So if you're asking a question, it does also get harder for
some humans and that's not what we are looking for.

That's a good point. Not only should a captcha be accessible by
sighted, visually impaired, deaf-blind, cognitive impaired, and other
disabilities not mentioned, but also deal with all languages as well.
It certainly sounds impossible, but what are the commonalities of the
above groups?
Clearly specific languages won't work. However, similar problems
arose in maritime and aviation industries where different nationality
captains were/are required to know specific "English" words to pilot
globally. So, the net may present some words that should be
recognized by all, but that's not up to me, but rather to the
consensuses of the net to develop. For example, perhaps "About" and
"Home" may be good candidates, if yo see what I mean.
If not language, what? Mathematical symbols, Dingbats, Miscellaneous
symbols, General Punctuation from the Unicode dB may be candidates
for a more universal basis for communication. But how does one convey
that information to everyone? Hell, some current browsers still can't
render Unicode correctly in the url's, let alone a way to "show" them
to screen readers. In addition, even OS's make it hard for user to
even enter/use those type of characters (except for Mac of course).
There has to be some commonality -- any suggestions?
