Unlike our Japanese quizzes, the choices in JPDrills flashcards are randomly chosen each time the card is served. Choices are randomly chosen from the pool of words already introduced to the user via the JPDrills levels system and not from, say, an unrelated JLPT N1 deck. Both systems have their respective pros and cons. A benefit of different choices each time is that a learners subconscious doesn't simply memorize the answer out of the same static available choices served each time. A disadvantage of randomly chosen choices is that sometimes the combination of choices makes finding the answer extremely easy.
