Input: Consider Input: I have bought several Revolution flavored teas.. white pomegranate and sweet ginger peach (not sweet but nice peachy ginger taste) and I loved them. However, this tea is not too good.. there is no pear flavor! not even a subtle one.. it is a bit bitter and really just like a plain white tea. If you like that, fine, but don't expect a pear taste!

Output: Negative

Input: Consider Input: My dog loves this food, and she has maintained her healthy weight for many years. The vet is very happy with her general health, coat, and teeth. Having the 16lb bag sent directly to my home without any shipping charges is terrific! The 16 lb. size is not available in my area.

Output: Positive

Input: Consider Input: Some reviewers must have a short memory. I've been eating Beer Nuts since childhood and the ones I ordered tasted like they always have (sweet and salty). Bought them locally until I couldn't find them anymore. Great product and price for 6/12oz cans.
Output: Positive
