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 have fed my dogs Instinct Raw Boost for years. I have two big dogs, one with digestive issues, and then added a third big dog to my pack, so that brand of food was too expensive when I have to buy a 21lb bag every week or so. Dog Food Advisor gave this 5 stars, so I tried it. My problem dog didn't have any problems at all transitioning to this food, and my Great Pyrenees with allergies has had no issues. I am extremely pleased with this food. I would highly recommend it.
Example Output: positive

Example Input: So super upset! I bought this and got 6 pairs of gold hoops. Not at all the style I ordered. I am super sad and would never order again for. This company
Example Output: negative

Example Input: Very happy with my new air fryer. I had wanted one of these for years and finally got the chance to find this really good one, here on Amazon. I can cook up French fries, make mozzarella sticks, I can even dehydrate meat for my husband and all kinds of other recipes simple and easy. It came with a recipe book and all the parts that I needed to have a really good air frying experience. It cleans up nice too. Very satisfied with my purchase.
Example Output:
positive
