In the example above, the second word is probably the one they already know (“my”), while they still don’t have enough answers for the first word (“tandozah”?). Everyone gets a different combination. They use one part to OCR the text and the other part to validate that you are not a robot.

One thing I’ve always wondered though was how a new reCAPTCHA ever verifies a human if the text was unrecognizable initially. For a short time, does a reCAPTCHA challenge just permit everyone–robots and humans–alike? Thanks for the article.
