Instructions: 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: Mackerel is a tasty alternative to salmon with nearly the same Omega 3 content. My local grocery store hasn't been able to get tinned mackerel for several months. No one can explain why. So I ordered a case of these and have been pleased with the quality and value. I'm reordering.
Output:
Positive
