A computer-implemented method, system, and/or computer program product shares information related to passages from an electronic book. An electronic book is opened to a user-selected initial passage. A passage block within the electronic book, which starts at the user-selected initial passage and ends at a community-selected terminal passage, is defined. A determination is made that members of the social community who have read the passage block have input a high incidence of incorrect answers to questions about the passage block, where the high incidence is greater than a predetermined value. Thereafter, additional help is provided to the user of the electronic book, where the additional help is information that members of the social community have deemed to be useful in correctly answering questions that had the high incidence of incorrect answers.
