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: 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: Patak's makes the best curry around. I frequently use it in my Yellow Chicken Curry Dish which is a favorite with both my husband and seven year old.
Example Output: Positive

Example Input: For anyone who is a seasoned Sencha tea drinker, this is tea is a total dud.  It barely tastes anything like fresh, high quality Sencha nor even older dried sencha leaves.  I had to throw this in the trash because it's simply dreadful.
Example Output:
Negative
