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: The set is beautiful and sturdy. Very comfortable seating and the blue color is pretty. There is a lot of nuts and screws involved in the assembly. We used a power tool to assemble. We had no trouble putting the pieces together. It took us two hours to get it altogether, when done it will have been all worth it.
Example Output: positive

Example Input: While I appreciated my shirt arriving on time I ordered a 2XL shirt and a large was shipped to me. The shirt clearly states LARGE but the sticker on the outside says XXL. Your quality control is not good and has messed up a birthday gift.
Example Output: negative

Example Input: I don't like to leave such a poor review, but this product was inedible. I don't know if the couscous was stale or had simply absorbed a strange, chemical odor from the plastic bottle, but whatever the reason, the taste of the cooked product was bad. After opening the bottle and immediately noticing the smell, I was hesitant to actually cook it, but I did, hoping the smell would dissipate. It did not. I cannot recommend this.
Example Output:
negative
