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: I wasn't sure this was spec'd for my G3 IBook, but another review and some looking into the hertz/watts thing convinced me. I'm hoping it'll be a backup for my G4 Powerbook too. It works fine. Seems to load up my battery as quickly as the original AC adapter; it's lighter and seems to be more compactable -- easier to carry around. I'd recommend it.
Solution:
Positive
