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

Bought this product as a gift and the first one didnt work - the lights wouldnt come on indicating charging. Completed my first Amazon return, and had a new one (that worked great!) before I could even get the broken one to the UPS store. Completely happy with the entire purchase (even the broken one because life happens and it was so simple to get corrected!)
Output:
positive
