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: Dynasty brand green tea is the best green tea I've ever tasted.  It never tastes stale, unlike brands I've bought in grocery stores.  This is because each tea bag is packed in a sealed envelope with a metallic lining.  The metal apparently keeps out moisture.
Example Output: Positive

Example Input: My dogs loved this product and I was happy to spend the money on it, but now that it's made in China- thumbs down, what were they thinking? I'll never buy it again. There are better products made in the USA. If you care about the well being of your dog, you will avoid products made in China.
Example Output: Negative

Example Input: It was worth the wait--Gluten Free Bisquick is just like the real thing!! Everything tastes the way you remember it. So make dumplings, pancakes or cheddar biscuits they are all as good as they can be!
Example Output:
Positive
