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 love Twinings Lady Grey but the most recent batch was pretty bad. Regardless of how I brew it I get an odd odor that masks the characteristic Lady Grey aroma. I used some older tea under exactly the same conditions and got a perfect cup. I've got 6 tins of this stuff and it is a lost cause.
Example Output: Negative

Example Input: I decided to give these a try since one of my good friends and her son raved about how good they were...Bad idea!  I almost ordered two since they were such a good price, I am so glad I didn't!  We don't care of these AT ALL!  The concept is nice, chips that are crunchy and better for you than most, BUT they taste funny!  They have a funny aftertaste and are not that enjoyable.  We have been slowly (and I mean very slowly) making our way through the 24 the box brought (we still have 19 left and we received them over two weeks ago) so they are not so horrible that you can't eat them, its just like forcing us to eat them so we don't have to throw them all away!  If you haven't had them before, I suggest trying them before committing to 24 bags of various yucky flavors!
Example Output: Negative

Example Input: RECONSIDER THIS FORMULA!!  Martek advertises this formula on their website!  "Although Martek told the board that they would discontinue the use of the controversial neurotoxic solvent n-hexane for DHA/ARA processing, they did not disclose what other synthetic solvents would be substituted. Federal organic standards prohibit the use of all synthetic/petrochemical solvents".  Martek Biosciences was able to dodge the ban on hexane-extraction by claiming USDA does not consider omega-3 and omega-6 fats to be "agricultural ingredients." Therefore, they argue, the ban against hexane extraction does not apply. The USDA helped them out by classifying those oils as "necessary vitamins and minerals," which are exempt from the hexane ban. But hexane-extraction is just the tip of the iceberg. Other questionable manufacturing practices and misleading statements by Martek included:  Undisclosed synthetic ingredients, prohibited for use in organics (including the sugar alcohol mannitol, modified starch, glucose syrup solids, and "other" undisclosed ingredients) Microencapsulation of the powder and nanotechnology, which are prohibited under organic laws Use of volatile synthetic solvents, besides hexane (such as isopropyl alcohol) Recombinant DNA techniques and other forms of genetic modification of organisms; mutagenesis; use of GMO corn as a fermentation medium Heavily processed ingredients that are far from "natural"  quote from: Why is this Organic Food Stuffed With Toxic Solvents? by Dr. Mercola - GOOGLE GMOs found in Martek.  This is the latest I have found on DHA in organic and non organic baby food/ formula: AT LEAST READ THIS ONE*** GOOGLE- False Claims That DHA in Organic and Non-Organic Infant Formula Is Safe. AND OrganicconsumersDOTorg  Martek's patents for Life'sDHA states: "includes mutant organisms" and "recombinant organisms", (a.k.a. GMOs!) The patents explain that the oil is "extracted readily with an effective amount of solvent ... a preferred solvent is hexane."  The patent for Life'sARA states: "genetically-engineering microorganisms to produce increased amounts of arachidonic acid" and "extraction with solvents such as ... hexane." Martek has many other patents for DHA and ARA. All of them include GMOs. GMOs and volatile synthetic solvents like hexane aren't allowed in USDA Organic products and ingredients.  Tragically, Martek's Life'sDHA is already in hundreds of products, many of them certified USDA Organic. Please demand that the National Organic Standards Board reject Martek's petition, and that the USDA National Organic Program inform the company that the illegal 2006 approval is rescinded and that their GMO, hexane-extracted Life'sDHA and Life'sARA are no longer allowed in organic products.  BUT I went to the lifesdha website and THEY DO NOT DISCLOSE HOW THEY MAKE THEIR LifesDHA!!! I have contacted the company to see what they say.  Also these are the corporate practices of Martek which are damaging to the environment as well written just last Dec 2011 at NaturalnewsDOTcom  The best bet is to just avoid the lifeDHA at this time in my opinion b/c corporate america cares more about the almighty $ than your health.
