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.

Example Input: My dog will do anything for these treats. Buying a five pound bag lasts about a year and they are dry so they are easy to put in your pocket and they last forever.
Example Output: Positive

Example Input: Glutino crackers are among our favorite GF crackers, but if you have a store in your area that sells them, that might be a better bet. About half of our crackers (in all 6 boxes) arrived broken.
Example Output: Negative

Example Input: These english muffins are okay at best.  They are very hard to cut and break apart easily making it hard to toast.  They definitely have to have something like jelly or peanut butter spread on them otherwise, do not taste the best.
Example Output:
Negative
