I think you have completely forgotten what it is like to be a beginner at chess if you think that someone who has just learned the rules of the game would be able to identify that the best move is to underpromote a pawn to force a draw.
It's not about forcing a draw but recognizing that the only reasonable move loses the queen immediately.
Assessing the ending is irrelevant. All one needs to know is that having 1 piece is better than having 0 pieces. Not actually always true, but that's the beauty of this puzzle - you don't need anything other than the most basic logic to correctly solve it, at least the first move.
