You will be given a definition of a task first, then some input of the task.
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.

When I first took a bite, I seriously thought I was eating dog food. These are disgusting. I searched the bag for "dog food" and the expiration date thinking that it was bad for one of those reasons. I don't know how anyone can like these.
Output:
Negative
