Input: Consider Input: This bone is nothing more than a big dog treat.  I have a 2 yr old Pit who ate through the souper in 5 minutes.  After reading other reviews I took it away from him and will save the rest for a later date.  I was hoping for a bone that would last a little bit longer as a chew toy and not just be eaten like a treat.  Will not be buying this again.

Output: 2


Input: Consider Input: I started using NuStevia several years ago.  Back then I had to purchase it from a health food store.  Thanks to Amazon I can now order and have it within a few days.  I never run out!  As for the product, it's the best.  I've tried several Stevia products but they have an after taste.  Not with NuStevia.  Please try if you haven't.


Output: 5
