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: This practically falls under the category of healthy snack - well, almost.  Single serving bags mean you won't be overeating and the fact that these aren't in anyway greasy because of the way they are made is a huge plus.  Nice crisp crunch.  The bags are filled with air, which for the most part do a good job of keeping the chips whole.  On the case that I got, though, two bags containted nothing but broken bits.  Of the rest most only had a couple of broken chips - some no broken ones at all.  I also noticed that you don't find nearly as much coating from flavoring on your fingers as I've experienced when eating other chips.  Purchasing it by the case to try out all of the flavors is a good idea and a decent value.  Some of the flavors are incredibly strong, to the point that I don't like them, so I won't be ordering this mixed case again.  Salt and Pepper just tasted like pepper, making this a very hot tasting chip.  The Seasalt and Vinegar is really strong on the Vinegar, which is a taste I don't enjoy.  I love BBQ flavored chips, but again, this was kind of strong.  I probably wouldn't purchase the BBQ ones in the future, but wouldn't say no if someone offered them to me.  The Original is really bland compared to these others, but not bad.  The ones I liked the most were the Sour Cream & Onion and the Cheddar, both with milder flavors.  I'd give this 5 stars if I liked all of the flavors.  Definitely high marks for the type of chip and the size of the serving and the fact that you can try all of the flavors in one order.

Example Input: This tea tastes almost as good as the tea you would get at an Indian restaurant. It's much better than getting a teabag and making it the English way, with a lot of water and a bit of milk. This is very creamy and tasty. My only criticism is that there aren't enough sachets in the box. Only 10. Since the directions say that you use one sachet for 100ml of water (approximately half a cup), it's not enough for a good cup of tea, so I use two. That means that one box is only good enough for five cups of tea. But it's a delicious after-dinner drink! I would buy this again if there were more sachets in a box.

Example Input: I chuckled a little when I read that this soda had no added sugar when I checked the label in the can since it already has 34gms of sugar anything more added and you'll have sugar junkies of whoever tries the drink.  The soda is tasty and quite fizzy, I think it has more carbonation than Fanta which goes flat easier.  The can is the typical size of an energy drink, but this is not an energy drink merely another fruit flavored soda.  It is flavored naturally, but that is the only difference from regular soda type drinks.
