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. 

Example Input: Fiber one products actually don't have real fiber.  They contain inulin (from chicory root) which is technically fiber because the body can't digest it.  Unfortunately fiber is defined by anything that can't be broken down easily.  These products do not contain REAL fiber. (The real fiber usually found in whole grain breads and bran cereals) So if it says "chicory root" or "inulin" in the ingredients, you can be sure you aren't eating the fiber your body can actually use.  So if you want lots of sugar and fat without fiber, this product is for you.

Example Input: For starters, I'm not salt or msg averse. I enjoy salty food like chips, jerky, and bacon. However, these pork rinds are ridiculously salty tasting. To give you a better idea of what I'm referring to, Kettle Chips Sea Salt variety have 55 mg of salt per 1/2 oz of chips. Lowrey's pork rinds have 310 mg of sodium per 1/2 oz serving. That's roughly six times the salt content of a food considered relatively salty by most people. I read a review on here saying that they were too salty and decided to order them anyway thinking the reviewer was some salt hating baby. Boy, was I mistaken. I wish I hadn't ordered these.
Example Output: 1

Example Input: I thought this was a great buy, but as noted by Scott D., the molasses content was not up to par.  I loved the higher molasses content "Sugar in the Raw".  Unfortunately what I purchased recently does not have the higher molasses content and I have twelve 24 ounce bags.  I guess I'll watch for the next crop.
