There are two modes. If you've never read the book, you're presented with a series of lines as would be found in a book report. If you have read the book, you're presented with a multiple-choice quiz. The quiz requires you to click on the letters directly (and not what they're saying). The quiz also supports typing the letters on the keyboard.
I made this from scratch specifically for others to remix. No special attribution is required. (CC-0) The quiz source supports providing more than four answers, but the first answer should always be the correct answer. Four possible answers are pulled randomly, and if none of them is the correct answer, one of the possible answers is replaced with the correct answer.
