Detailed Instructions: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
See one example below:
Problem: I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: We were surprised and confused when opened up the Amazon shipping box. The battery has been removed from the retail packaging and wrapped in a bubble wrap with a seal labe said "new". When looked closely at the battery, it's obvious that this is not the same one as what we have in the camera. I'm not sure if $29.94 is a deal for a non-original battery. We strongly urge Amazon to faithfully update the product description, or this is considered a deceiving.
Solution:
Negative
