Given the task definition, example input & output, solve the new input case.
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: I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Polarity: Positive
Output: True
It's a positive review because the owner of the dog is satisfied with the product and mentioned that their dog appreciates the product. Also, the polarity is positive. So, the correct answer is True.

New input case for you: Just off the phone with them (Aug/12) and they said that yes they stopped putting BPA in the liners in Oct/11. Of course there is old stock on the shelves so I asked how to tell whether the liners we have are the "old" (with BPA) or the "new" (without BPA) and the person there said to look at the inside the surface of the lid. If it is all white then it is BPA free - if it is metallic or gold then it's the "old" lids which did contain a BPA layer. Thought this might help some of you out there!
Polarity: Negative
Output:
True
