How do I know if they are "pointing me in the right direction"?

Once again, you assume the conclusion that their comment is helpful and correct and meaningful, and you work backwards to excuse their poor explanation that they justified with "let's say it's a quiz".

And if you don't like my reply, take your own advice and go away. Why do you care what I think of their phrasing? You're not going to get me to stop anyway, or the dozens or people who upvoted me.

Or keep swearing at me and getting downvoted, whatever floats your boat.
