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.

I just opened this product and there are only three light bulbs -- not four. And there is a white dust in the pocket where the fourth light bulb should be. Did it break and someone just removed it? Am I being exposed to broken florescent remains? This was shipped with other Amazon items in an undamaged box. The bulb had to have been removed before shipping. This may be a quality control issue.
Output:
negative
