Add more types of quizzes and questions to stories

Expand the variety and increase the number of interactive quizzes and comprehension questions that accompany each story. For instance, consider adding a standard set of 3-5 multiple-choice questions at the conclusion of every story, as suggested by a learner. This enhancement aims to provide learners with more comprehensive tools to test their understanding of the story content immediately after reading. Different question formats could also be explored to assess comprehension from various angles.
