Indexing convention for this study guide

Each main question unit begins with a decimal number.  The first number (i.e., on the left of the point) refers to the chapter of the book in which the question if anchored.  The second number (i.e., to the right of the point) places the question in the entire series of questions emerging from that chapter.  The third number (in parentheses) indicates the page in the Bantam Doubleday Dell Publishing Group paperback edition of the text (1988).

Thus 1.3 indicated the third question concerning Chapter 1, and 2.5 points to the fifth question in the series of questions over Chapter 2.
