Considering I'm not familiar with the specifics of the modification you're speaking about I can only speculate as to it's functionality.

The benefit to reCAPTCHA is it's something any human can answer. Questions, regardless of how easy they are, may be interpreted wrong due to language barriers or possibly even mental capacity. The goal of a CAPTCHA isn't to test the users knowledge, it's to simply confirm they are human.

One of the added benefits of reCAPTCHA is the fact it takes something as trivial as registering on a forum and uses those "human processes" to do something productive. Helping to translate words that even the best OCR software in the world cannot translate is helping to advance the digitizing of books printed before the digital age.

Not to mention, reCAPTCHA uses 2 words to authenticate humans. One of the words is one that has been proven to be previously untranslated by bots. That's a pretty good security measure, if you ask me.
