A secret question appears to log in

Hello, I am trying to log in to FB and it says that:

Please review recent activity on your Facebook account

Your account was recently accessed from a location we're not familiar with. For your protection, please review your recent activity to make sure no one is using your Facebook account without permission.

Reviewing your activity takes just a few moments. We'll start by asking you a couple of questions to confirm that this is your account. (If we recognize your computer, you'll be able to skip this step.)


After that I put a code of two words and it pops a secret question regarding my third school teacher which I never put so I obviously don't know the answer. Do you know how can I skip this step to enter facebook?

Regards
