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: We'll see how these work out in our family over time. I'm not sure that I am disciplined enough to make good use of them, although it might be a good technique for teaching my dog. They appear to be good for what they are, a very tiny, but healthy, reward. Right now I can visualize them being used as a reward for following commands, a training tool. I was surprised at how tiny these treats were. They seem to taste good enough, but they are miniscule! They are just a fraction longer than a small paperclip and about half as wide, maybe 1/4 as thick. My dog was a little annoyed, but took it when I gave it to him. That was yesterday. Today he came in excited to get his "treat", looked at it as if to say, "You've GOT to be KIDDING!" Then he took it and ate it. A little later I offered him another one. He put it on the floor and looked hopefully at his stash of larger treats, but when he didn't get one, he went back and took this one. I think these might be good for rewards for obeying commands. Treats? That's stretching it. They may also be good for my son's dog who rarely gets treats because she's overweight and would eat the whole entire refrigerator full of food if allowed. At least she would get a treat. Large treats take her 5 seconds. She'll probably inhale these, one second max. I like the fact that these are low-fat, with no added salt, no refined sugar, no artificial flavors, colors or preservatives. It says, "Treats Baked With Natural Peanut Butter."
Example Output: Positive

Example Input: I normally bake from scratch but when I saw this pink lemonade cake mix with matching frosting I just had to try them both. This cake can be made two ways: with or without egg yolks. I recommend with as the cake will be nice and moist as a result. This cake would also be just as good with plain white icing or just a dusting of powdered sugar. You can make it as a layer, bundt, or sheet cake, or as cupcakes. I picked it up at the grocery store recently for about $1.80 per box, the frosting was about the same price per can. I ended up going back and purchasing more for later as I believe this is just a seasonal flavor and Pillsbury will pull it from the market at some point. If they do I hope they bring it back every spring. Until then I'll be stocking up.
Example Output: Positive

Example Input: I agree with other one star reviewers... this tea smells like grass.. If you get lucky, you can get the right balance and make a decent but always weak cup of tea (ok-- delicate if you prefer instead of weak).. if you use a little too much then it is grassy and/or bitter. I guess you have to really like Sencha Green to use this tea.
Example Output:
Negative
