Which of these sentences might best serve as a topic sentence of a paragraph telling how to write a book report?

You didn't really provide enough information, but I'll help you out anyway. You should always start a book report by stating the book title, name of author, and your opinion in the first sentence. So you could say (book name) by (author name) was a (good adjective/bad adjective) book.

Hope that helps :)
