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: Well this stuff was crumbly and would not stick to itself. It was like wat sand. I couldn't knead it or work with it at all. Added water and pushed it in the mold and it cracked in thousands of pieces. Worthless stuff don't buy it.
Example Output: negative

Example Input: We love this kit, which includes everything we need for birthday decorations. It saves time for us instead of looking for birthday related decorations here and there in different stores. It is a decent product and has a great quality! Thank you.
Example Output: positive

Example Input: These labels do not "remove clean once the job is done". They are not removable and I learned that when I went to replace a label that I had adhered only a few minutes prior and it peeled off the underlying product. I am now forced to purchase more of these labels so that I can put new labels over the existing since by removing labels I will expose damaged product. Very upsetting since I relied on the removable characteristic.
Example Output:
negative
