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.

Example Input: I was taking this supplement to help me sleep. They were effective once I started taking two capsules just after supper. However, I did not sleep through the night. I am still trying different supplements
Example Output: positive

Example Input: These definitely do not feel safe. I was baking something at 400F and took the tray out and looked at the mitt and it was completely black where I picked it up..... NOT WORTH BUYING.
Example Output: negative

Example Input: Not really a good tool to urinate standing up for women unless you pull your pants down or you are wearing a very big pair of sweats or something like that. I got this thinking I could use it to go into a urinal. I'd just get a regular urinal and just make a snug fit with my own doing.
Example Output:
negative
