Example Input: I was extremely disappointed with the fabric and color when it came. It is obvious that it is of poor quality but I guess you get what you paid for 10 bucks.The zipper of the plastic cover of one set was broken.I bought 2 queen sheets and I wanted to return both purchases if only I did not have to pay for shipping.Do not buy this!!!! You will regret it.
Example Output: Negative

Example Input: Paxton Quigley's book is a compliation of parts of other books on firearms self protection. It's a bit overdone, and probably would scare the average woman thinking about protecting herself. Women seem to have special problems protecting themselves. They usually do not want to hurt anyone, and they will do all most anything for a baby or a family member before they will do anything to protect themselves. However, women that are able to continue to practice with a hand gun, usually become quite proficent. They know that they don't know, and they listen to instructions. Most men think they know it all already.
Example Output: Negative

Example Input: Simply put, this book is what other writer strive to achieve. It has a little of everything: Fantasy, Adventure, Exploration, Mythology, Romance, and Scientific Theory of the day. Fascinating exploration of what is really in the unused 90% of the mind.
Example Output:
Positive
