We have this point in our unordered list ...

We state:

"Whenever an interactive CAPTCHA is implemented, a variety of
alternative challenges must be
offered that engage different sensory or cognitive capabilities of the

We humans possess a variety of intellectual strengths and weaknesses. To
fail
to offer a variety of challenges is to ignore this simple truth."

Isn't this saying the same thing, just in very different words?
