Can you name the longest river in Europe? Can you identify an Archaeopteryx and an Allosaurus? And do you recognize the flags of India and Italy? Maybe not right off the bat, but readers 9 to 12 will find out soon enough as they make their way through 60 topics, arranged by three levels of difficulty. Don't be daunted by the word "quiz," because the subjects here will undoubtedly appeal: rockets, dinosaurs, knights, sports, classic games, mythology, lost cities, extreme weather, and a host of animals (with an emphasis on the dangerous ones). Multiple color photos appear on every page, and the answers to the trivia questions appear upside-down at the bottom.
