Detailed Instructions: 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.
Q: These are very good chocks and can be used for small aircraft, cars, other wheeled equipment. The only thing I would caution is to pay attention to the measurements given and actually look at a ruler to make sure the size fits your need. If that size fits your need, they don't make any better than these.

positive
