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: I thought the impeller was broken so I purchased a new one and unfortunately learned that it is the filter itself that is no longer able to pump water. I bought this a month ago. My turtles are not happy.
Example Output: negative

Example Input: Now we are living a bark free life! Within two days it had cut out 99% of non-essential barking! At last you can feel peace and quietness in our house! We love our beagles but they were driving us crazy! It really detects barking from far away, now we don’t even hear our neighbor dogs. Great quality and cute btw...This has been a life saver! We are able to get proper sleep now!
Example Output: positive

Example Input: This was already gelled in the container when I opened it. Since I had purchased two, I was hoping the other one would be okay. It was even worse. There is a no return policy on this item, so I am out of luck. I wanted to try something different than ModPodge for glass transfers.
Example Output:
negative
