Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Input: Consider Input: Despite the many reviews from folks who had to return one or more Sansa Views before getting a functional one, I figured the manufacturer must have cleared up their quality problems to stay in the market. Wrong!!!!My brand new Sansa View 8 totally stopped functioning about 20 minutes into its first use. I'm very disappointed to have waited for my order to be filled and now must wait again for a replacement. I'm more than a month into my purchase and I have nothing to show for it but a paid bill.Amazon has not stepped up at all, either. The order was filled by a vendor whom I've never heard of before. Amazon refers buyers to that vendor's customer service and takes no part in satisfying the purchaser.Lots of room for improvement on the part of all three providers.

Output: Negative

Input: Consider Input: The book contains 280 pages of text, 25 pages of refenreces, 7 pages of INDEX, and many figures and cartoon to explain the concept of author's hypothesis. Barbieri was a development biologist at MRC in Cambridge, NIH, and Max Planck.This is a typical anti-Darwinism semi-pseudoscience book. I picked up the book because the book cover had a Chomsky's accolade. It's not as obvious and outrageous as Intelligent Desing-sort of book, but the author cites his own book to explain his main points. Many biological facts in the book are real and correct, but there is no scientific logical structure to support the author's "semantic" theory. I was struck by the fact that this book was published from Cambridge University Press.


Output: Negative
