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: I purchased these to replace the straws that I use to get at Starbucks every morning. Starbucks no longer gives straws, so I wanted a replacement that is environmentally concise. These are great. They fit perfectly through the opening in the new Starbucks lids and held up all day.
Example Output: positive

Example Input: Worst PLA I have ever tried. Problems getting it to adhere to the bed, really gooey and stringy. Every print fails! Tried every different setting in cura and all different temperatures and nothing works.
Example Output: negative

Example Input: For one, it's too short. Additionally, it makes such minor correction it's hardly noticeable. The fact that it's leather covered is helpful. If you need a more than minor correction I would recommend seeing a orthopedist for an orthopedic insert. I only used this a couple times.
Example Output:
negative
