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: Company sent round knob and not the lever as advertised. Company told me to uninstall to send back instead of sending me the correct lever instead offered me 20 rebate, smh smh
Example Output: negative

Example Input: Clip is smaller than OEM, they also don't expand nearly as well as the original and don't have a relief cut into them for easy removal... Half the installed clips have fallen out in less than 500 miles so I guess that relief isn't really needed. These are far less superior that the OEM clips. Buyer beware, you get what you pay for...
Example Output: negative

Example Input: Some of the best, coherent, concise writing and reasoning I've seen from a scientist. One of the most brilliant men I have had the pleasure of discovering. I recommended to an atheist friend of mine who told me Sanford is right after reading just the first two chapters of his book. He is still atheist, so if you have preconceived notions about this book and the author and his worthiness of your time I suggest you put your pride aside - if Sanford is right it has serious implications for your worldview and nearly everything you've been taught about our world, life, and yourself. Don't be afraid of the possibility that what we have been taught is wrong put that ego aside and just read
Example Output:
positive
