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: We are not vegetarians, but everyone in my family likes healthy nutrition. In this book we found very good recipes. This book is great for vegetarians, or even just for people who want to cook more vegetarian dishes, such as we. Recipes are easy to follow and I believe you will enjoy these dishes.
Example Output: positive

Example Input: I’ve been having knee pain for the past few months so I decided to try this support brace. I can’t believe how much support it does provide and my knee pain has gone down significantly. It’s slim so you can wear it under pants while at work but also looks fine with shorts. So glad I found this and it is helping with my knee pain!
Example Output: positive

Example Input: I bought this to use as a general hobby saw for various uses a year or so ago. Ultimately it has sat unused as the quality of cuts are extremely poor. Perhaps good for hack cuts (think what you can do with a jigsaw) but not for anything else. FORGET ABOUT ANY PRECISION WITH THIS. And I do not mean for small pieces... really for anything. Wish I had made another decision. Will likely give away to local good will shop.
Example Output:
negative
