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.

Input: Consider Input: I cannot get my dog to use this no matter how hard I try. My dog is the most food motivated dog I've ever known. She will do ANYTHING for carrots, lettuce, ice cubes... even her own kibble. But regardless of what I put in this thing, I cannot get her interested in this toy to save either of our lives. I even tried clicker training her on it! She doesn't associate it with food no matter what I do.

Output: Negative

Input: Consider Input: I have bought several Revolution flavored teas.. white pomegranate and sweet ginger peach (not sweet but nice peachy ginger taste) and I loved them. However, this tea is not too good.. there is no pear flavor! not even a subtle one.. it is a bit bitter and really just like a plain white tea. If you like that, fine, but don't expect a pear taste!

Output: Negative

Input: Consider Input: These brownies are good, but the flax seed texture can be a real turn-off. To minimize it, I added a little whole wheat flour, splenda and cocoa - BIG improvement and my guests never complained (like they did the first time I made the brownies!).
Output: Positive
