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.

Input: Consider Input: Our family has liked every other flavored we have tried (BBQ is the best). We like sweet potatoes so we assumed would like these pop chips.  I was wrong, no one in the family likes the sweet potato pops chips.  I highly recommend you go to a store that sells the sweet potato before deciding on purchasing a large quantity.

Output: Negative


Input: Consider Input: The rice flour in it is a crude gritty grade (cheap?). If you've ever used Thai rice flour <a href="http://www.amazon.com/gp/product/B000EYC096">Thai Rice Flour - 16 oz</a>, you know that rice flour does not need to be this unpleasantly gritty.  I tried compensating for the grit by using Bisquick Gluten Free to make Johnny cakes since the cornmeal is sort of gritty. But sadly, after you chew you are still left with this unpleasant grit like fine sand in your mouth.

Output: Negative


Input: Consider Input: I have tried various brands of stevia, but I always come back to NuNaturals.  I buy the 12 ounce container because I use it to sweeten everything.  If you have a sweet tooth as I do but don't need the added pounds, then this is the ticket for you.  I drink a lot of tea, and this is my sweetener.  A lot of other stevia brands leave a bitter after taste, but this is the best that I have found to resolve that problem.  Highly recommended.


Output: Positive
