Definition: You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.
Input: Delivered by UPS, this product is just about perfect. It does not have a disagreeable smell and the dogs love it. It is much less expensive than prescription dogfood and our dogs are thriving on it. You can even see an occasional pea and/or carrot. No grain to worry about.
Output:
Positive
