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: These are amazing as an on-the-go snack! I keep one or two in my car (currently cold weather) for my daughter for the days I end up working late and know dinner won't be ready before she's hungry again.
Example Output: positive

Example Input: I got this scooter bc I read on the reviews that it came with a helmet! What a disappointment for the price to get this and not see the helmet in the box - and the face of the birthday child when we told her that she couldn't ride it on the road!
Example Output:
negative
