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.

I bought this product to keep my boxer entertained. She is very food motivated and very smart. The problem is that she tries to get the food out by any means necessary. This results in her being very ruff on the toy. I had to take it away for fear that she would break it.
Output:
Negative
