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: This is a great multi-use sauce.  Great for using as a baste when grilling - fish, chicken, shrimp, pork, etc.
Example Output: Positive

Example Input: This was the first time I tried purchasing a food product over the internet, and as feared I was sent something other than what was pictured.  This package contains Chia Seed POWDER, which I assume is ground up seed (or the remainder from packaging whole seeds) that you have no way of identifying whether or not has additional filler.  Not going to bother returning a $7 product, but just disappointed when the page advertises whole seeds.
Example Output: Negative

Example Input: Good, but I add a cup of whole wheat flour and a tsp. of baking powder along with a couple of TBSP. of Cocoa powder because I like brownies a little higher and more cake like.  They come yummy and with the added flour, they're not too sweet.
Example Output:
Positive
