In this task, 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: Kit is basically unusable. The negative lead has no continuity and seems to have a broken wire. The kit has a lot of useful items in it, clips and such, but is rendered useless with a broken lead.
Example Output: negative

Example Input: I hope you love the ones you by from this company and that it flatters your face without trying them on even once because they do not offer any returns. They look nice but they look awful on the shape of my face. But I guess I'm stuck with a pair of sunglasses I can't wear.
Example Output: negative

Example Input: My son is really getting a lot from this. He is 7 years old and has been diagnosed with Autism. He doesn't care to color the pictures but he does all the other activities and you can really see it is helping him. Not to mention he is excited about going through the book. For something that has been so hard for him, it is as if he is gaining confidence just from reading and practicing what is in the book.
Example Output:
positive
