Example Input: I ordered the spotted dick. After eating I felt a little strange. I went to the bathroom and to my horror realized that I had this horrible disease. Luckily 1 gallon 128 Floz Tuscan Whole Milk cleared this up for me.
Example Output: 1

Example Input: Melitta's rich, flavourful product is a delicious treat comparable to coffees with a much higher price tag. It is a plus that the decaffeinated version does not sacrifice flavour. Highly recommended.
Example Output: 5

Example Input: The benefit of this drink is that it is "no sugar added, 100% juice," which tastes basically like fruit soda. I can see it as a good alternative to traditional soda, especially for kids and teens. However, for adults I think the drink still tastes really sugary, despite the fact that sugar has not been added. I ran for my toothbrush as soon as I was finished. However, the taste is good and the kiwi berry was a nice flavor. For young people with a sweet tooth I would recommend it, but I think grown ups will have a more difficult time jumping on board.
Example Output:
