Example Input: The candy arrived with some white waxy stuff on it; almost as if it had partially melted at one point.  Tasted chalky.  Not interested in a partial refund.  Next time find a way to make sure candy is not stale.
Example Output: 2

Example Input: These are way better than rancid grocery story peanuts, but they weren't as good or as fresh as I'd hoped. I imagine that they'd been stored too long at amazon before being shipped.  Too bad, because if they're not going to be absolutely fresh, why would I buy these again?
Example Output: 3

Example Input: I added 3 tbsp of sugar and half tsp of pure vanilla and a pinch of alum  free baking powder and  coconut oil for oil  and it came out soo good. My son loved it . I liked it too. The fact that it's all the major allergens free makes it better.
Example Output:
