Example Input: This tea is not so tasty in my opinion. But one thing about opinions is that every one has one and we do not always agree.
Example Output: 3

Example Input: I love, and use the empty containers for medicine/advil in my purse, desk, suitcase. Also line with felt to keep earrings. Perfect little size to disguise small valuables when traveling and LOVE the mints. Tiny and powerful without burning my mouth.
Example Output: 5

Example Input: I really wanted my 2 yr old cat to like these treats because I already feed her Wellness wet food, which is excellent by itself. Perhaps she's too used to the Whiskas Temptations that I normally give her, but she did not like the jerky bits at all. I did notice it was hard for her to pick up because they're pretty flat, and the texture is chewier than what she's used to. The 3rd time I gave her the treats, she vomited it out. Looks like it's back to the less healthy alternative.
Example Output:
