Definition: 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.
Input: My YorkiePoo thrives on this dog food. I ran out two weeks ago, no local source, bought a competitor's so called equivalent only to see my Quinn suffer from itching and belly aches. I ordered this from Amazon yesterday, free shipping, they sent it out hours later and I recieved it today!
Output:
Positive
