Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example is below.
Q: I've read this book with much expectation, it was very boring all through out the book
A: Negative
Rationale: Review writer does not like the book because it was boring, therefore it is a negative review.
Q: Unless they sent me the wrong product by mistake, the foot cushion picture and description does not match the item delivered. I was under the impression I would receive two (a pair) of water filled foot cushions that I could insert into my shoes. Instead I received ONE foot cushion, filled with another material (not water) that you attach to your foot via a toe strap. I was definately not happy with the item and sent it back for a refund. Luckily for me Amazon has a great return policy... they make returns very easy!
A:
Negative
