How the quizzes work
Every question has three big boxes to tap and nothing to type, and Peabody reads each one aloud. Tap a box and Peabody says why it's right or not; a wrong box dims and you try again, and only your first tap counts toward the score. Nothing is saved or sent.
The examples come from the 118 real projects on these pages: what each one changes, measures and keeps the same. The numbers in the table quizzes are made up by a fixed rule from a project's own levels, and the quiz says so. Grown-ups can check every answer and why under each quiz.
