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.
Input: I tried the shocker on the lowest setting and it had no effect. I gradually inched it up until my dog felt it and then he fell out on the floor and started foaming at the mouth. No wonder I was reluctant to try this and will NEVER have another item like it
Output:
negative
