Highlighted word, audio, animations, and questions all together help the reader visualize what the story is about. If they can visualize they can better comprehend and learn.
Really liked how the questions are asked throughout the story instead of at the end. The animations and questions combined help the reader understand/comprehend/remember the story
I thought the questions were higher level questions and not your basic true/false or multiple choice. There could be multiple answers and you can give a separate answer. These help with critical thinking, comprehension, and simply getting the reader to create an answer on their own instead of simply selecting something based on a guess. A lot of times a multiple choice or a true/false can question can be figured out logically (It's not A or B so it must be C) and the reader can be correct without actually understanding why that is the answer.
