TASK DEFINITION: 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.
PROBLEM: It was time to order cat food again and I thought I'd give the Natural Balance line a try.  My cat loves fish, so I figured that the Tuna and Shrimp Recipe would be a big hit.  Nope.  Both cats in our house gave it two thumbs down votes - neither of them would touch it.  What finicky little critters they can be sometimes [sigh].

SOLUTION: Negative

PROBLEM: 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.

SOLUTION: Negative

PROBLEM: Brought this product for recording a radio program from home. Along with the Behringer C-1 microphone, provides a cost effective solution.
