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: I was never much of a hot sauce fan until I tasted Black Market Hot Sauce. I was listning to the radio one morning and the creater/owner was giving an interview, It sounded interesting. The D.J.'s were sampling the sauce and raving about it, So I picked up a bottle at the local grocery, It's so good ! I keep a bottle in the kitchen and an extra bottle on hand for gifts and for taking to potlucks,barbecues and party's. Happy to see I can buy it online at Amazon.
Example Output: Positive

Example Input: I have a 2 1/2 year old 60 pound German wirehair pointer.  We feed this food during hunting season due to his increased metabolic needs.  He burns so many calories, he eats 8 cups of this food a day (with zeal).  We use the large bites to help keep the tarter and plaque off of his teeth (and to slow his eating).  Due to the high quality of this food, he can keep up his energy, keep his weight up, and recover more quickly from scrapes/bumps from running the field.  Our vet's exact words were, "Your dog is an example of perfect health."  You may think the price on this food is high, but it is worth it.  You get what you pay for.  Also, consider the canned version of this food.  It is a nice way to feed/hydrate a dog after a long day hunting - just give them an hour to settle down first.  On a side note, we feed Diamond Naturals Beef and Rice in the off season.  We have no digestive issues transitioning from one to the other (we switch over a period of a few weeks).
Example Output: Positive

Example Input: O. N. E. Coconut water is delicious and refreshing. It is amazing how it rids me of cramps in my calves and lower back.
