You are given an amazon food product review and its polarity (positive or negative). Your task is to answer "True" if the specified sentence and its polarity match; otherwise, answer "False".

Example Input: Although I had some concerns about product with initial shipment - my concerns were far overshadowed by the excellent, prompt and courteous response from vendor about my concerns.  Customer service that seems a rarity these days - was absolutely exceptional!  Will definitely keep this vendor in mind when I have need for other craft supplies/products. 
 Polarity: Negative
Example Output: False

Example Input: I held off ordering these for a while because I was concerned I might not like the taste. I've tried some of the organic green teas and found flavor can really vary between brands. Six boxes seems like a lot to take a chance on. I really wanted something powdered to take to work though, so I gave it chance and it worked out.  To me, this product tastes great.  I am thrilled to get something unsweetened.  I wanted these to use at the office, but find I like them so much I mix them up at home too. I just wish they were a little cheaper as they go really fast.  I went from thinking 6 boxes would be a lot, to experiencing them as hardly enouugh!  Basically, this product has a mild taste, never bitter or oily and not gritty (but it will need to be remixed if you don't drink it down quickly).  The powder does mix well, it's really a very fine powder and does not look like leaves just mashed up or anything.  It blends completely into the water, BUT it doesn't stay mixed over a long period of time.  So, if you are letting it sit in the glass about 20min or so as you sip away, it's useful to get one of those shaker bottles to keep it mixed as you go along.  That works for me, no complaints.  I am very happy with the product.  I will order again. 
 Polarity: Negative
Example Output: False

Example Input: I have tried literally dozens of teas since being introduced to the Russian custom of preparing and drinking tea, and the Ahmad Imperial blend is probably my favorite of all of these due to the fact that it is equally delicious hot or iced.  I buy the three-packs as needed from Amazon and go through them rapidly. My family loves it and my friends have it in their homes now too, try one box of it and you will love it too. 
 Polarity: Positive
Example Output:
True
