I get the impression that about half of the questions are list based. And the questions are about 10 words long. If that's the case, then using the algorithm you mentioned, you have a 1 in 20 chance of getting the captcha right. So yeah, it's a completely useless captcha system. That number should be 1 in a million or higher, not 1 in 20.
