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.

[EX Q]: I was excited to see that Amazon is selling 100% Kopi Luwak. However, these beans were a huge disappointment because they had no aroma and flavor at all. I'm guessing that they sent stale beans because there was no roast date printed on the bag.
[EX A]: Negative

[EX Q]: 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.
[EX A]: Negative

[EX Q]: For canned soup this is very good clam chowder.  Those who give it 1 or 2 stars are comparing it to homemade soup or restaurant style soup.  I would buy this any day over other brands.  You can tell it is all natural and without loaded msg, salt and other nasty ingredients.  Pure and clean soup.  Those who rate it badly, some say it has no flavor or there aren't chunks in it.  The flavor is mild, but that is good- not overwhelmingly clammy and not over salted like conventional brand canned soup.  If I want to, next time I will add a potato cut up in chunks to boost it's contents- not a big deal to do.  I would prefer to do that than buy a conventional brand that doesn't care about healthy ingredients and sourcing of ingredients.  I will buy this again- good source of iron as well.
[EX A]:
Positive
