The TL;DR is that recaptcha uses one word that it knows as the solution and
the second is one that recaptcha is determining the answer for. Recaptcha
is currently trying to turn print archives of newspapers into normal digital
text. So it takes unknown words and has users try to solve it. It then
stores the results and starts assigning confidence values to the unknown
words. So if you get a answer with a relatively high level of confidence
it''ll let you through. If you get a brand spanking new word,
it''ll let you
type just about anything.
