@prettyflowers1,
I haven't read the book, will read it if I run across it.
Who gave you that you set of questions? Does that person or website have any personal or academic clue why the author decided to write the book? Would it matter to you, if you somehow found quotes about that online?
Is the book an argument or thesis? Maybe it's a book about an interesting person in an interesting time and place, with pros and cons developed in the "portrait".
Why did the author choose the chapter topics? Because they made sense to her while she was telling about the subject; perhaps there is an overall point of view pushing the story. That can be an author bias - is that what you are reading? Or maybe the arrangement was based on an editor's advice.
What kind of sources did the author use and why? Is there a bibliography at the back of the book?
Please figure out what you think about the book. Read it twice if you need to.
Talk with your professor/teacher if you need to.
