What are some good CER (Claim, Evidence, Response) prompts for The Curious Incident of the Dog in the Night-Time?

A claim, evidence, and response prompt (CER) asks the student to state a claim for what they are arguing, provide evidence that supports their claim, and explain their reasoning for this. These prompts are for essays or longer answers that require a student to demonstrate analysis and critical thinking, as opposed to short answer question that check students' reading comprehension.
Here are some ideas for The Curious Incident of the Dog in the Night-Time; students should answer these questions in CER format.
How does Mark Haddon develop Christopher's character?
How do the maps and diagrams in the text help us to understand how Christopher sees the world?
Christopher's mother and father make choices regarding their son. Do his parents make the right choices when it comes to his care? (Alternatively, ask the students to choose one thing a parent did and analyze it, such as his father's choice to hide the letters; was this the right choice? Why or why not?)
Christopher has an aversion to being touched. His parents tell him they love him. Can Christopher fully understand their love? Does Christopher demonstrate affection toward any of the characters? How?
Which of the characters understands Christopher the most?
