This study guide provides a series of questions designed to guide the reader toward many but certainly not all, of the most important ideas presented by Drs. Duffield and Van Cleave. The questions follow the structure of the book, chapter by chapter and section by section. Page numbers are noted beside each question to direct the student to the answer provided by the authors. This allows the student to place the study guide beside himself or herself while reading the textbook. It also assists teachers who wish to refer to a question during a discussion in the classroom. Hopefully, these questions will stimulate much discussion and provoke further research on topics of special interest.
