Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example is below.
Q: I've read this book with much expectation, it was very boring all through out the book
A: Negative
Rationale: Review writer does not like the book because it was boring, therefore it is a negative review.
Q: This is just a chapter of the Volume 4. Do not buy it and save your money. These sellers are so clever that they give no mention of the pages -- hence fooling us into buying these thinking them to be books .Go buy the book -- The emergence of Industrial Societies.
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
