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 consider my Sheltie to be an intelligent dog, but the noise of the toy makes him back away. And I can't tell you how many times I've "demonstrated" how to get the kibble out. He just waits until I do it. He could care less about the thing, and he's very food motivated.
Example Output: Negative

Example Input: Even after shaking the cup and only using 6 ounces of water, this "hot cocoa" (pretty sure there's not a lick of real chocolate in it) still tastes horrible.
Example Output: Negative

Example Input: This stuff is pretty disgusting.  I don't care if Madonna, Tom Cruise or whatever celebrity invested in the company and carries a container of it around for photo opps, it tastes bad.  And as far as rehydrating better than water, umm, don't think so.  It might replenish potassium, although, unless you are participating in the Olympics, you probably are not going to risk a potassium deficiency from physical activity.
Example Output:
Negative
