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: ...or the good reviewers' taste buds are weak. This is some disappointingly weak coffee. I'm not some crazy "gotta have my jet black sludge to get through the day" coffee drinker - I'd say my favorite (and my wife's) is Caribou Blend. This blend is WEAK, it can't hold half-and-half or even just whole milk without being wiped out. Now, I will say I brew it on the "large cup" (9.25 oz, I believe) setting on our Keurig, so maybe it's a bit better on the 8oz setting, or even the small setting. But Caribou (we also like Donut Shop, Green Mountain Kona Blend 10%, etc.) can be easily brewed on 9.25 and hold a good bold taste. This coffee doesn't hold a CANDLE to any of those. Now I'm stuck with 40+ of these. Blech...maybe the guests won't mind it! :)
Example Output: Negative

Example Input: This baking soda works great for cooking or for health reasons. I take it for acid indigestion and heart burn. Just a 1 tsp in a half glass of water and it's gone. I use it to make my body more alkaline, so it's great for changing your pH level in your body!
Example Output: Positive

Example Input: There was nothing wrong with the pastries--everyone seemed to like them, so you'll be fine as long as they don't mess up your order. I ordered two boxes of pastries for Christmas gifts, but the shipping was slower than expected and, more importantly, they only sent *ONE* of the two boxes. I tried calling them and got a recording--figuring they were probably just busy because of the time of year, I also sent them two e-mails. So far I have not heard back. The shipping label was attached directly to the SINGLE pastry box (rather that being affixed to a larger cardboard box that could possibly hold two) and said BOX 1 of 1, so I know it wasn't a delivery service problem. They simply only shipped one of the two boxes that I ordered. Mistakes can happen to any company, but the fact that they are hard to get in touch with and won't return my e-mails is just poor customer service.
Example Output:
Negative
