The answer key sat open on the desk. Leaving it closed is a grade they can’t give you.

An unguarded opportunity is a question about what you do when nothing is enforcing anything. Taking it produces a number that means nothing, and you are the one person who will know that permanently. The result you earn honestly may be lower, and it is information you can use. The other one is noise.

Leave it closed and take whatever you get. If you needed those answers, you now know exactly what to go and study. That is worth more than the marks would have been.
