Example Input: Husband and Grandaughter LOVE this cocoa... Make it for them all the time as I drink my coffee.. My husband is a very picky person but for some reason he really likes this one product and wants me to keep it in stock here at the house.. Loves it at night after dinner on cold evenings.
Example Output: 5

Example Output: 1

Example Input: The sodium and sugar (often corn syrup) in tomato sauces is frightening.  Plus, w/them you eat white pasta to boot but w/salsa you eat rice and beans.  Trust me - don't buy your sauces around your meals, get salsa and plan meals around it.  They arrived in a day or two and the bottles were shiny and fresh, I was afraid of warehouse dust and old stock.  The vendor did really well.
Example Output:
