In this 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.

Example Input: This item was much shorter than I expected it to be. I have an alaskan malamute and this did not do the trick in trying to help with his pulling. If you have a small dog, this will work for you.
Example Output: negative

Example Input: These are very large mouthed straws. I thpught they were regular size, but they are more of a smoothie or larger type of straw. I'm not sure who needs a straw this large.
Example Output: negative

Example Input: This product comes vacuum sealed and you have to stuff it yourself. The legs are very long, out of portion with the rest of the body. The seams split very easily, creating multiple holes and the stuffing falling out. We are very disappointed in the quality of this product.
Example Output:
negative
