Given the task definition, example input & output, solve the new input case.
You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.
Example: I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Output: Positive
It's a positive review because the owner of the dog is satisfied with the product and mentioned that their dog appreciates the product.

New input case for you: My daughter, living and working in DC this summer, introduced me to this product while home for a visit. She encouraged me to give the plain version (just pure coconut water) a chance first, and by the second container, I understood the amazing qualities of this drink. I felt so refreshed, hydrated, and healthy! I later tried the kind with pineapple, which is also delicious, but I think the plain is more effective and purely refreshing when really hot, tired and thirsty, while the sweeter fruit infused version will be amazing as part of a cocktail. Can't wait for 5:00!
Output:
Positive
