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: Either I got 15 tubes that came from a bad batch lot or they are not selling the right Harissa. I bought 15 tubes thru Amazon from Parthenon Foods and used 4 of them so far and after putting the whole tube it still isn't spicy at all. Normally a whole tube would get you to sweat a bit!!!!! This seems to be a case of false representation. I buy these tubes in Canada at the grocery store all the time when I am up there and they provide a nice kick and spice (as they should). What's up with dat?
Example Output: Negative

Example Input: These chips are very good. Wish we could purchase them in our area. Great chance to try them in this offer.
Example Output: Positive

Example Input: My cat had a severe allergic reaction from this food resulting in deep, crusty, oozing, lesions on his face around his mouth, up to his ears, and down to his neck. On close examination of the ingredients, one unusual additive is sunflower seed oil in this and other Fussie Cat flavors. He's back on his old food and healing nicely. I'll stick with the less expensive brands and save on vet bills from now on.
Example Output:
Negative
