There are some issues with this quiz as there are different lists of Monaco's wards. According to Monaco's own website (Monaco.me) there are 10 of them: Monte Carlo / Spélugues, La Rousse / Saint Roman, Larvotto/Bas Moulins, La Condamine, Monaco-Ville, Fontvieille, La Colle, Les Révoires, Moneghetti/ Boulevard de Belgique and Saint Michel. No mention of Jardin exotique or St Devote (both on your list), but La Colle, Les Révoires and St Michel are missing from your list.
From my research, the wards of Monaco were restructured sometime in the last few years, and the English Monaco website is outdated. La Colle, Les Revoires, and St Michel were all changed and/or merged with other wards. If you could give definitive evidence to the contrary, I would delete the quiz as there is already an SVG quiz of the previous Monegasque wards. The French Wikipedia for Monaco (which I trust much more than the English one for obvious reasons) lists these wards as the current ones, and other sources do as well.
