Example Input: This is by far the best hot cocoa I have found yet for the Keurig. I love the assortment and the peppermint is my favorite. I would give these try for sure if you are looking for some hot cocoa K-cups. All the other selections for hot cocoa that I have tried were just okay tasting. These are AMAZING!!!! LOVE THEM! I will order these for sure again!
Example Output: 5

Example Input: According to the side of the can, it's 100% juice with a balance on the carbonation. It tastes great if not for the chalky aftertaste. The low carbonation made it feel less of a soda and more of a juice. I probably wouldn't buy it in the store because of the weird taste.
Example Output: 3

Example Input: This bags are very difficult to open with the aid of some tool, such as scissors, don't even try without scissors. They are crispy and taste like chips that aren't advertised as being salted. They definitely aren't healthy, because I can feel the grease all over my fingers when eating them, and I can see the grease at the bottom of the bag, too. They are high-quality chips, and deserve to be put on your table.
