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 was disappointed to receive Earth's Best Organic Snakin' Fruit Rings Banana because it hurt my child when she bit into the hard and stale treat.
Example Output: Negative

Example Input: I bought these chips looking at its sale rank as one of the most sold chips on amazon.com. Unfortunately, I was highly disappointed. Way too much vinegar and they aren't like regular potato chips, some weird "pops".
Example Output: Negative

Example Input: I've been using this "low acid" coffee for a few weeks now and along with the taste, I enjoy not having an "acid stomach", especially the "morning after". To me, there is no difference in taste between it and regular coffee. I give it 5 stars.
Example Output:
Positive
