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.

Let me give you an 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.
The answer to this example can be: Positive
Here is why: It's a positive review because the owner of the dog is satisfied with the product and mentioned that their dog appreciates the product.

OK. solve this:
Arm & Hammer's baking soda is aluminum free, they just don't write it on their packaging. I wasn't sure so I called them and they said there is no aluminum in it, and they would have to state it if there was because people take the product internally. This leads me to believe that there just isn't aluminum in baking soda. And researching it showed me that there might have been in the past, but not anymore and not for a long time. I resent that Bob's Red Mill writes "Aluminum Free" on their package and then charges a premium for their product. It's also arsenic free, I hope. If they label it "Arsenic Free" will we assume other brands aren't? I don't like that kind of marketing.
Answer:
Negative
