Example Input: Thia is the saddest story I have ever read! Poor girl---she doesn't have a chance with finding a happy life! The cards are all stacked against her from the git-go!
Example Output: Negative

Example Input: This book preaches a very right wing kind of economics. If you can imagine one of Rush Limbaugh's readers or helpers writing a primer on economics, then this is it. Keep government small etc. The author most likely was an Austrian school follower. As it is avaiable free on Limewire, maybe get a free copy on the Net or browse it in your local library. No need to buy unless you want to flesh out (sic) the ideas of Mr Limbaugh et al. The book relentlessly hammers home the ideas that government should be amall, self interest drives the economy forward and that state intervention is bad.
Example Output: Negative

Example Input: I was quite pleased with the condition of this book, as well as it's hardcover, and the footnotes, definitions, and reading reviews for beginner readers of the genre. I am, of course, a huge fan of the Scarlet Letter itself and this copy served its purpose well. One of the few disappointments was that the color of the cover seems to look a little more coral, or pink, than scarlet or red. Also, the back cover is white, and I am most definitely one for appearances. I would have like a slightly more classic looking cover. Nonetheless, the binding will look fair on my bookshelf. Over all the book was clean and well taken care of, and was shipped to me with great haste; A Good Buy.
Example Output:
Positive
