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: Product was never received nor money returned.  Four requests have been ignored.  I will probably never again order anything through Twang or from Amazon.  Also, I will spread the word about these sites.
Example Output: Negative

Example Input: Watch out, we had a couple of bad tasting bags from a 40-count box from costco recently.  When opening up the third, many of the popcorn kernels inside were odd looking, inconsistent.  It is too bad, so now we are going to air popped popcorn, after using Orville's  bags nearly daily for a few years.  Eden's organic popcorn was OK so far, but harder to find.  Now will try Bob's (red mill?) popcorn kernels.  Hoping none of these are of the genetically modified type of corn.
Example Output: Negative

Example Input: I buy skinless sardines packed in water to keep my intake of sodium and chloresterol down.  For about $2 a can including tax and delivery I feel I am getting my money's worth.  I cannot get these kinds of sardines at the local supermarket.  Sardines are somewhat tasteless.  I put the sardines on salad and top the salad with olive oil and red wine vinegar.  If I eat the sardines as a sandwich, I used mustard, which also has no salt and chloresterol.
Example Output:
Positive
