Gr 5-7--The titular six questions in each book are clearly stated and are the guiding questions for its chapters. Authors include sufficient background and enough detail to answer the queries; and sidebars, quotes, primary-source excerpts, and period art and contemporary photos augment the texts. Although these topics have received wide coverage in extant titles, and the books offer little new information, the question-and-answer format will help readers identify and understand each topic's most salient aspects and will sharpen their nonfiction reading skills, making the books attractive options.[Page 58].
