As you go on reading, some of your earlier questions should be answered. Go back to your initial questions and use the right-hand column to record the answers you have found. If there is not enough room on the grid, number the entries and use footnotes to refer to the answers.
You may still have unanswered questions even when you have finished reading the entire text. These may have been left deliberately vague for the reader's own interpretation. Use the clues you have to form your opinion or to come to a reasonable conclusion.
