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 usually feed Earth's Best baby food to my grandson. He has never had a reaction of any kind to any baby food I have given him. This is the first time I have tried this particular variety pack. I fed him the Peach Oatmeal Banana and Apples and Apricots for breakfast this morning. Shortly after I noticed he was scratching. I looked and he had a rash. I remembered reading a baby food review where someone mentioned an allergy so I checked and yes it is this variety pack. I don't know what is in it that would cause this type of reaction. Unfortunately I fed him two different jars so I don't know which one caused it but I don't want to take a chance of him having another one so out they go. Just thought I would let others know.
Example Output: Negative

Example Input: I heated these up in the microwave, and they do not microwave evenly. some will be burnt and hard as a rock when others will be just right. since you dont get very many in one bag, and since about 1/3 dont cook right, you barely get any pork rinds and throw the rest away. Maybe I am not cooking them right, but i followed the directions...
Example Output: Negative

Example Input: I love hot chocolate and was very excited to find a variety pack, however, these are gross.  Horrible after taste, my kids dont even like them.  Now I have 3 boxes of the stuff that no one will drink.  Very disapointed.
Example Output:
Negative
