Example Input: This batch was horrible.  Since most regular coffee were out of stock, I tried this one.  It tastes and smells awful.  Do not buy this flavor.
Example Output: 1

Example Input: I would not order these K-cups again.  Maybe I'm spoiled with Godiva hot chocolate, but I think Swiss Miss hot chocolate has more chocolately flavor than these K-cups and I wouldn't waste my money on these.  It comes out a pinkish color that is not appetizing at all.
Example Output: 3

Example Input: We have two dogs and after a few weeks of switching to the Beneful Healthy Weight we've noticed very unpleasant results. They whine to go outside much more than they ever have and actually had bowel movements right in front of us if we don't get them outside in time.  Our dogs have gone from needing to go outside a few times a day to 6 or 7 times daily to handle the number of bowel movements they have. My theory is this dog food just goes right through the dog and not much of it actually is being utilized by the body. Which makes me wonder how many nutrients my dogs are actually receiving.  Poor dog food in my opinion and should only be used if your dog needs a laxative. I will most likely be going back to Purina One.
