Nice quiz! You should accept "Proclamation" and "Presentation." Or at the very least "Proclamation of the Kingdom." And I've heard people announce the final Luminous Mystery as "The Last Supper" as well before. Maybe that wouldn't be a bad type in?
Some of the answers need more variations to be accepted. Tried "Finding in the Temple", "Presentation in the Temple, and "Proclamation of the Kingdom" and got those wrong.
