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: I suppose some people might rate this product higher as it is a great substitute for Bisquik, however I didn't like it because everything I made from it tasted like Bisquik.
Example Output: Negative

Example Input: I am a big fan of Sorghum flour for my baked goods. It gives everything a bit of sponge (especially cakes) and adds an extra bit of sweet to the baking. I highly recommend this for baking flour mixes - you may not want to add it to savory recipes though because of the light sweet flavor.
Example Output: Positive

Example Input: Purchased these for first time.  No second time.  The beans will not soften up nor will the pasta.
Example Output:
Negative
