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: The first couple of bags were great. Really fresh, smooth, great taste. I thought I'd found the perfect coffee bean!! The next 5 bags .. stale. I canceled my order and went back to buying whole bean coffee from the supermarket. You pay a little bit more, but I've found that most of the time, the supermarket coffee is fresher. I prefer the taste of Weaver's but too many stale bags.
Example Output: Negative

Example Input: Ok--I just bought BIsquick GF and the first thing I tried to make were the drop biscuits (recipe listed on the box).  These are not the kind that are rolled out & cut--these are "drop "biscuits.  The results were very tasty.  The taste of this GF bisquick is very much like the original, but the taste is not as tart as the original.  If you want a similar buttermilk taste, you will need to use buttermilk instead of milk in the biscuit recipe.  I noticed something else that was odd and might be a problem for anyone new to cooking; it seems that the amount of mix called for is not quite right.  I read the side of the box and it claims that there are 3 2/3 cups of mix in the box (11 servings of 1/3 cup each).  The biscuit recipe called for 2 cups of mix. I measured heaping teaspoonfuls into a measuring cup and I don't even have a cup of mix left in the bag?????  I know this mix doesn't have wheat flour and maybe that kind of flour measures differently, maybe if I dug into the bag with a cup, I would have used less, but the recipe came out right.  So, there must be a misprint on the box.  I am assuming I measured properly because I have biscuits that can be dipped in gravy, smothered with butter & jam, or sliced to make those yummy McDonald's breakfast sandwiches. By following the instructions, I have A LOT of biscuits.  If you are single, or just cooking for two; you might want to cut the recipe in half.  You will still have plenty and you won't go through the box so quickly.  This mix cost me around $5.00 and I don't have enough left to make anything else, without buying another box; which I will because these biscuits are really, really good.  Still, if you are watching your budget, don't prepare more than you need.  About these biscuits:  yummy, fairly golden (because the recipe calls for eggs), and they can be sliced with some crumbly edges, just like glutenous ones.  Without the eggs, you probably won't get the nice eye-appealing color.  Even though they are drop biscuits, you still have to cut-in shortening or margarine. If you don't have a cutter, you will need to use a long fork.  That is more difficult, so if you are a celiac that has been craving biscuits; buy a cutter.  It will cost you as much as a box of this mix.  The biscuit recipe also calls for milk, so if you want that nice tart taste that is reminiscent of the original bisquick; you will need to use buttermilk.  The mix is made up of rice flour, sugar, leavening, potato starch, salt, & xanthum gum.  Many mixes and goodies made with rice flour taste grainy.  Bisquick has done a fantastic job with the rice flour.  It is not grainy at all; I repeat, it is not grainy at all.  For those of you new to celiac cooking; using a starch such as corn, potato, or tapioca is normal and adds a lightness to the baked item that wouldn't be possible with rice flour alone.  Leavening is simply baking soda or powder and is necessary for rising.  The sugar and salt are for flavor and consistency,  and yes, they are necessary.  As for the Xanthum gum; it is a perfectly natural ingredient and it gives celiac-safe baked goods a bit of elasticity (acting as a replacement for the gluten).  You will find Xanthum gum in just about every baked goodie made for people with celiac disease.  Can you just make your own mix and spend less money?  Sure, but you will have a very difficult time finding rice flour as finely ground as the rice flour that is the predominant and main ingredient in this mix.  The other recipes listed on the box are for pancakes, waffles, strawberry shortcakes, pizza crust, ultimate chicken fingers, and oven baked chicken.  You can find more recipes on their website.  I recommend this product for the taste.  I do wish that more mix was in the box, for the price.
Example Output: Positive

Example Input: So when you purchase beans of a reputable brand you would expect to get fresh beans. They tasted old from the opening of the bag and so even if the date was well in advance of it's expiration I can only surmise that quality control was an issue in the storage or shipping of the beans. But I won't be ordering any more espresso beans from this company unless they can correct this.
Example Output:
Negative
