Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Solution: Positive
Reason: It's a positive review because the owner of the dog is satisfied with the product and mentioned that their dog appreciates the product.

Now, solve this instance: A word of caution to anyone considering buying these: Read the ingredients first! I made the mistake of thinking they would be the same as the longer (Oberto brand) ones our local Costco used to sell, so I ordered up 10 bags to get the volume discount offered at the time. I knew something wasn't right as soon as I opened up the first bag and got a whiff. Then I read the ingredients and was shocked when I saw that they actually use pork hearts as the top ingredient. To eliminate any doubt, I tasted one.. we've been using them as expensive doggy treats ever since.
