Instructions: 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.
Input: The cereals had a weird odour and also the colour is a slight tinge of greenish/greyish. Even though, the tins were originally sealed and expiry date is in 2012! Is there a production problem for the cereals? Perhaps amazon.com should do a sample check! This is a serious problem and should be investigated immediately as the cereals are meant for our dear babies!
Output:
Negative
