Twenty-five sets of four. In each one, exactly one is a real thing that a real animal actually does. The other three sound just as likely and aren't. Pick the one you think is true, and you'll find out about all four.
How this works
Nothing is counted, timed or scored. There's no running total and no wrong-answer buzzer — picking one just turns the answers over, so you learn four things either way. Guess, or read the hint first, or skip straight to the answers. It's all the same.
