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 ordered from Amazon because the only 5oz cups locally seem to be child oriented and not for an adult bathroom. Ha! My dixie cups have riddles on them and are as cartoonish as the ones I could have bought down the street. I'm throwing them out and getting a hard plastic cup. So mean to send something other than was pictured!!!
Example Output: negative

Example Input: Lens are super reflective making everything blurry. They do not reduce eye strain, on the contrary, they make it worse. I wouldn't waste your money on these.
Example Output: negative

Example Input: Three people's night of horror described with exquisite skill brings the reader to a level of understanding not usually found in stories of Britain during the blitz.
Example Output:
positive
