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: One word, yuk. OK, based on the 20 word minimum; barely edible dry, chalky, flavorless, not even improved or masked with a good slice of cheddar cheese.
Example Output: Negative

Example Input: Please be aware that although dogs absolutely LOVE these treats, that they may have caused a recent unexplainable illness in our 9 month old Mastiff pup. He was getting 1 or 2 a day of these chicken jerky's for about a week and then suddenly became very lethargic, along with vomiting, diarrhea, and had no appetite "except" he would eat only these treats and drink water. Vet thinks he'll recover OK, but advised us to stop feeding them to our dogs. These are still "Made in China" and in 2007 reports had shown that dogs were getting sick from these and other brands, and there are still reported cases today. Just be careful and watch your pets closely if you are feeding them these. We will no longer feed these to any of our dogs, ever. Wish Dogswell would manufacturer these in the USA again.
Example Output: Negative

Example Input: 10 out of 12 cans are seriously dented , and, the dents did not occur during shipping. These were dented befor they were packed in the case of 12 at the factory. These will get trashed because it will be more of a pain to return them. I will never buy these again !!! Amazon did refund my money without having me return the cans. Cudos to Amazon. They are a class act!
Example Output:
Negative
