Example Input: Since a DOP product is not readily available at my local grocery stores, I got really excited when I saw the photo of this product at the Amazon website because the photo states that this product is "D.O.P. Certified."  But when I received the shipment, it was a huge disappointment.  It was a different product than what the photo promised.  (I can buy the one that was delivered to me at my local grocery stores very easily.)  Very disappointing.............
Example Output: 1

Example Input: This is good coffee, but nothing to write home about.  I like the grind, which is finer than most ground coffee, although I prefer grinding the beans myself.  It has a bold, but not bitter, taste.  Even though I'll stick to Eight O'Clock as my coffee of choice, this one certainly isn't objectionable and is better than most cups you'll get at the diner.  And it's certainly better than Folgers, MH, and other grocery store brands.
Example Output: 3

Example Input: One of my cats is allergic to fish and beef. This formula is one of the few she can eat, and it has much better ingredients than the prescription diets available at the vet. Both of my kitties are very active, have soft shiny fur, and neither are fat. Dry food reduces tartar buildup on teeth, also.
