In the book "wonder", what do you consider the climax of the book? why do you consider it the climax?

I have not read the book, however, I can explain the proper way to determine the different stages of any properly written story. 

There are 5 parts to each story. These, together, are called the plot. 

The 5 parts of a plot are Exposition (also known as the introduction), Rising Action (Complication), Climax, Falling Action (consequence), and the Resolution (The end). These are listed in chronical order. 

The Exposition is the beginning - a time for introductions to characters and settings. 

Rising Action is when a complication arises in the story, and the main character reaches a point or subject that needs to be addressed. 

Climax is the peek of the story, the moment when the complication of the story reaches a moment of high turmoil and becomes the most serious. 

Falling Action is when the characters of the story begin to work towards solving the problem at hand. 

The Resolution of the story is the ending, the point in the story when the problem is solved or in whatever way dealt with. 

I'm sorry I can't be of much more help, as I have not read the story myself. I hope this helps you determine the correct climax and get the question correct - though, it sounds more like a question that you will get credit for, simply for trying and making a good argument. Best of luck!!

Yes no matter what a bible says because church and state are separate
