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 went back to the allergy medicine I was taking before. This did not help at all. I took it for a week, then gave it to my husband. He was unimpressed, said the generics we usually take work best for him, too. Very disappointing.
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: Light weight and good maneuverability. For some reason, it is wet inside the package when I received it. Maybe the seller did leak test before they send it? Don't drag it on the ground. Even the heavy duty ones will break that way.
Example Output:
positive
