Clair Obscur: Expedition 33 kicks things off basically in medias res, with not much in the way of exposition waiting for you. That's both a good thing and a bad thing, as the game feels much more organic without throwing three novels' worth of backstory your way. At the same time, you're bound to feel lost for a little while.
One of the ways in which Expedition 33 gives you at least some context on what's going on is via Antoine's surprise pre-Expedition quiz. Featuring just three short questions that you may or may not be able to correctly answer, Antoine's quiz does have a rather handy reward: a prize Token to spend in one of the stalls just behind Antoine.
To be fair, Antoine's pre-Expedition quiz isn't too challenging to figure out, and Antoine himself gives you more context on the story behind these events via regular dialogue, but you're probably going to want that Token the guy's offering, so why not get it right on your first go? Here are all the correct responses to Antoine's questions:
Answering all three of these questions correctly has Antoine give Gustave his festival Token, which can then be spent on a strange old key, a weird Picto, and a questionable new hairstyle for Gustave. You don't seem to be able to get these items later down the line, so we recommend chasing down the two remaining festival Tokens by speaking to all the nearby NPCs, to boot, and grabbing all three prizes along the way.
A bonus Token? Why, yes, I’ll take that.
