But is there any test that could be given that NO ONE (human) would have
any trouble with? If not, then there needs to be awareness of what kind
of test to provide based on your expected audience, and possibly a
decision tree for coding a test based on something about the client
browser. A simple example would be that if you can tell the browser
supports images, assume the person can see and give an image test.
Otherwise, give a simple quiz that's pretty universal or maybe
customized based on a country code earlier on the form.

This sounds like a good topic for an eVolt article! Or probably someone
on another site has already written one.
