Example Input: Newman products have been used in our home for years. After researching Newman's Adult Dog food I felt confident in giving the food to our two cocapoo's. They love it! One of them wolfs it down in 4 seconds! Really, I timed it. With so many companies recalling dog foods,I felt the Newman company being organic would be more reliable. Keeps me from worrying so much as I pour that bowl of food for them.
Example Output: 5

Example Input: I was really impressed with this.  There are many flavors, and quite a bit of heat.  With this and your favorite brand of cocunut milk you can make some great Thai curries at home.
Example Output: 5
