The Grand Line Quiz is a quest that runs throughout One Piece Odyssey, testing your knowledge of the series to earn some rewards. The first time you encounter the quiz is in Alabasta, where a girl called Zoner tries to convince you of the importance of trivia. She proposes a quiz, and lays three levels of questions before you. Answer them right, and you get a prize.
After Alabasta, you'll find a Grand Line Quiz master in each of One Piece Odyssey's main story locations, all with quizzes prepared. Most importantly, if you complete every quiz and the questline, you'll get your hands on a Treasure Chest Key, and considering how rare these are, it's well worth it.
If you're still making your way through Alabasta, you might want to know the correct route past the Ravine of No Return. Otherwise, here are all of the One Piece Odyssey Grand Line Quiz answers. It's worth noting that while each level contains the same questions, they are sometimes in a different order, which seems to happen if you fail and try again.
