Edit: I accidentally refreshed the page and it offered alternative questions for ID validation, such as high school of graduation and SSN. But it's still absurd to expect someone to even humor the premise of the prompt.
That would be a bad idea if the "correct" option is available. This is a DoB check without actually displaying your real DoB on the page, which could be used as PII verification by a malicious actor. If the correct astrological sign is listed and you say "Does not Apply", it will count as a wrong answer.
Crappy way to do this, but they're trying to walk a line between confirming your identity (or at least that you know the sensitive data of the person you're spoofing) with multiple choice questions and not creating a security vulnerability where someone can leverage their site to compile sensitive data on individuals.
