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: Consider Input: I adopted my dog about 6 months ago and he had digestive problems that the vet could find no cause for. He would get diarrhea with mucous in stools regularly. His stools would vary from constipated to unformed soft stool. I decided to switch him to a better quality food and did a lot of research. Newman's Own had all the qualities I was looking for, so I switched him to it gradually - 1/2 Purina One and 1/2 Newman's Own at first and gradually more Newmans' Own in the mix until finally 100% N.O. Ever since switching about six weeks ago, he has not had constipation or loose stools. I also don't hear his tummy roiling after meals like before. And despite what a few reviewers have written, the chicken and beef used in the pet food, while not "organic", is "natural" and raised without hormones and antibiotics.  According to [...] ingredients list: "Natural Chicken - Raised without growth hormones and antibiotics and fed only a 100% natural, all-vegetable diet, the chicken meat provides amino acids essential for muscles, hormones, enzymes, antibodies and structural and protective tissues." Also, the beef is free-range anad range fed w/ no hormones & antibiotics.  For me the evidence is clear - this is good quality food, my dog loves it and I love that when I buy Newman's Own products, the royalties go to charity!

Output: Positive


Input: Consider Input: There is contradicting information.  The description says Senior Greenie Large, while the photo shows "regular" as well as 27 treats versus 27 ounce.  Anyone that reviews and can clarify the actual product would be much appreciated.

Output: Negative


Input: Consider Input: Local grocery stores don't carry this cereal so I order it. It is full of nuts, raisins, and other great stuff. I cut up a banana in it instead of adding sugar. My favorite box cereal.


Output: Positive
