Definition: In this task, 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: I buy this coffee alternative every few months. Today, I received it and the bag had turned into a hard rock! I hit it on the counter to see if it would break up. It did somewhat but there are large chunks in the bag that I won't be able to use. Sadly, when I went onto Amazon to return it, I found out the item was NOT returnable! Perhaps that will be my last purchase of this product.
Output:
negative
