As to broadening horizons, sitting at a table with an assigned book is less likely to do that than a life filled with going, doing, seeing, touching, tasting, hearing and communicating honestly from inside while learning. Children DO have questions when they're in the process of learning things. It doesn't broaden horizons for a book to tell them which ten questions were the RIGHT ones to have at the end of each chapter.
