In this task, you're given a review from Amazon's food products. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral or mixed, 4: good, 5: extremely good. 

Ex 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?

Ex Output:
3


Ex Input:
Wrigleys' 5 FLARE sugarless gum is Wrigleys' sugarless replacement for their "Big Red" cinnamon gum. 5 flare seems to be difficult to find in stores. Thanks to Amazon I always have a supply. 5 FLARE is also the longest lasting gum I have ever experienced both in flavor and durability. It is positively the best cinnamon flavor currently on the market.

Ex Output:
5


Ex Input:
Now if you could just make it sugar-free also?  I know, I don't want for much.  :-)<a href="http://www.amazon.com/gp/product/B004391DK0">Bisquick Pancake and Baking Mix, Gluten-Free, 16-Ounce Boxes (Pack of 3)</a>
