The Picture of Dorian Gray. Dorian Gray. This is a 10 question quiz that tests the COMPREHENSION & ANALYSIS of the 15th chapter of The Picture of Dorian Gray. ANSWERS ARE INCLUDED. All questions are multiple choice. Each quiz in the series becomes increasingly more difficult as they test for comprehension of plot, definitions in context, analysis of literary devices, and function of literary devices. This is a great way to follow up the reading of each chapter. I also sell the complete pack of Dorian Gray Quizzes for $5.00. The complete pack is 20 10-question quizzes.
