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.

If I could give this food a zero I would. I tried it out and the dogs loved it until they all had the runs for 2 days. It was horrible, smelled bad, and I would never get it again!
Output:
Negative
