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: Busy Buddy Kibble Nibble has been a great toy for my dog, but Tug-a-Jug was not.  Within 10 minutes, she had gnawed the "challenge" rope into 6 pieces.  Maybe it's good for an older dog but definitely not for my vigorously chewing 8-month-old puppy!
Example Output: Negative

Example Input: What I like about them: 1) Very thick chips. 2) No trans fat and all natural, according to the info on the bag. 3) Flavor, but that's a subjective thing. 4) 2oz bags, which keep you from eating too much at one time. Just set a limit of 1 bag.  Cons: As another reviewer said, there's a lot of oil in them chips. What I do is place a paper napkin on a plate and pour the chips on them. Wait a few mins before eating and the napkin will soak some of the oil off. It seems gross that there is so much oil on the chip that a napkin will soak it off, but it's true! And at least this way, you'll get rid of some of the oil.
Example Output: Positive

Example Input: I'm surprised how much it tastes like coffee. To be completely accurate, it tastes like a watered down coffee (like the kind you get at hotels) with hazelnut flavor -- and a *very slight* earthy undertone. If someone gave me a sip and didn't tell me what it was, I'd think it were coffee, let's put it that way.  There's not all that much root per teabag though, and since I like strong coffee I only use 6 oz of water per bag and steep it covered for 15 mins. Then with some cream and sugar it's quite good.  As for the liver tonic claim, well dandelion stimulates bile flow and supposedly helps clear out some stuff gunking up the liver. I don't know about that yet, but so far I haven't noticed any ill effects from drinking this. I feel fine, if not outright good after drinking a cup, but that's as far as I can confirm the effects.  And with even decaf coffee containing 5-15 mg caffeine per serving, this stuff being completely caffeine free is a blessing for those of us who go bananas and light public property on fire when we get the slightest bit of caffeine. Anyone who needs a coffee substitute, do give this a try.
Example Output:
Positive
