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: I used it with my dog a couple dozen times, and she thoroughly enjoyed it. One time she managed to unscrew the bottom, and with that experience, she fixated on the bottom as the "ultimate solution" for the last morsels that weren't coming out from tilting and dropping the toy. She cracked through the hard plastic, breaking both the lid and the jug. The toy is advertised for "heavy chewers" but the container obviously doesn't hold up. I hope the store will offer a refund.
