Teacher: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.
Teacher: Now, understand the problem? Solve this instance: We've originally bought this as our dog's first food and then switched to Wellness. Dog had runs for a few weeks hoping it would go away then went back to Newman's own and now our dog feels a lot better. Never switched his food ever again.
