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: After reading some of the reviews, I got nervous and opened a bag from my recent order expecting the worst! No worries here. All bags are in great shape and expiration dates aren't until June. Chips, at least from the first bag, taste like they are supposed to and all is good in the world! By the way, fifteen bags for under thirty dollars is a ton less expensive than the going price around here at the local grocery store so, yay team!
Example Output: Positive

Example Output: Positive

Example Input: I am writing this because this product KILLED my in-laws 2 year old YORKIE. They have been breeding Yorkies for 18 years and this was the first product they have used, that KILLED one of there dogs. They started using this product this past summer. Sweetie (the dog) was chewing on the GREENIE chew in front of both of them, when she started convulsing.  They immediately took her a 1/2 mile to the vet, by the time they arrived there, Sweetie was DEAD.  The Greenie had Pierced her TRACHEA.  Please be aware od how dangerous these could be to small dogs.
