“The Good Question! series continues to offer interesting facts in an appealing fashion. Working within a set format, the skilled authors organize questions and two- or three-paragraph answers in ways that introduce and cover each subject appropriately. On each spread, clearly captioned illustrations -- maps, drawings, close-up photographs, and realistic images -- face the text. The questions are those a child reader might ask. . .  . Why Did T Rex Have Short Arms? introduces these early reptiles, describing how and what we know about their physical characteristics and behavior, and offering the most commonly accepted explanation of their extinction. Colorful illustrations introduce a wide range of species, though no explanation is provided for the artist's color and texture choices.. . . . Attractively presented, with up-to-date, accurate information, these science titles are a first choice.”
