Example Input: Makes pretty good cocoa and a lot easier than on the stovetop.  Not as sweet as I would prefer and needs to be stirred to keep it in suspension.  I guess I can add marshmallows:-)
Example Output: 3

Example Input: Ew...I love Canada Dry and Schwepps, and I decided to try this brand because it was cheaper and it looked authentic. Not sure how the regular (non-diet) kind compares, but this tastes so diety--it's gross. I usually drink diet soda and don't mind the taste of diet coke, diet dr. pepper, diet sprite, (other diet gingerale, too) but this is REALLY GROSS. don't get it! You can definitely taste the ginger, but the overly saccharine taste ruins it.
Example Output: 1

Example Input: I had so hoped they would be close or better than Cheetos Flamin' Hot but they aren't. They were NOT past the expiration by  3 months but they did taste stale and almost flavorless even though you get a tiny after burn. I gave the rest of the case to the food shelter.
Example Output:
