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.

Example Input: It is pricey and has high fructose corn syrup in it. I dont see why they dont make it more natural, is it really difficult to make it HFC free?
Example Output: Negative

Example Input: 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.
Example Output: Negative

Example Input: I use the powdered tea powder in my fruit smoothies.  Provides you all the health benefits of green tea.  Love the product and use both the plain and lemon ginger.
Example Output:
Positive
