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: I first read this book when I was in 7th grade, and am rereading it now, in 11th grade. This is an amazing story that my dad convinced me to read, and I've become hooked on the whole series! Auel gives the reader not only meticulously researced information concerning culture, vivid descriptions of the neanderthals, and geography, but also a twisting, inviting plot that makes the book impossible to put down! Thus Clan of the Cave Bear(and the entire Earth's ChildrenTM series) appeals to a wide audience. Adventure, history, and an eloquent storytelling style are combined with excellent results.
A:
Positive
