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: Read all the great reviews, so bought this item. Instructions are extremely inadequate; could not figure out how to put together. Returned immediately.
Example Output: negative

Example Input: Love the product but sellers need to pack it properly. One bottle's cap was destroyed and the product was all over the box and the other bottles. I lost about 50% of the product in one bottle so instead of a deal, this turned out to be an expensive item. Simple fix - tape the tops down. Wrap vertically - not horizontally.
Example Output: negative

Example Input: Really does a good job of pulling the dialogue out on the tv shows. Over all sound is great. Lots of available adjustments which I really like. I added a woofer and it works great with the sound bar. We are very happy with the purchase.
Example Output:
positive
