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.

Ex Input:
My daughter always has worn a size 10. For the first time, they were too small. Unfortunately, I have now waited too long to return, but we have never had a problem from other Amazon sellers for a size 10 sandal. These will have to be discarded and we will just have to find a more accurate Amazon seller with the correct size.

Ex Output:
negative

Ex Input:
This plaque is a very thin piece of cheap wood. The lettering is sometimes hard to read. Very disappointing and too embarrassing to give as the gift I had planned.

Ex Output:
negative

Ex Input:
These are perfect for my purposes. Thy're the right size, the colors make keeping track of my medicines 100% easier, they're good quality for a very fair price. I have a small Dymo tape labeler which I attach to the outside for further identification.

Ex Output:
positive
