You will be given a definition of a task first, then some input of the 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.

No doubt this is great if you are on a diet and need sugar-free but this stuff taste so artificial and the coloring is way too strong. The sweetness leaves a strange unbearable aftertaste. I'm stuck with 20 tiny boxes and I don't think I'll order these again.
Output:
Negative
