Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Example: I've read this book with much expectation, it was very boring all through out the book
Example solution: Negative
Example explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: I had lost the original book that I had purchased so I chose this oneTo replace the first book of this Earth's Children Series. I love this book very much and reread it immediately. This soft cover volume is easier for my elderly fingers to handle while reading. This is a series that will never grow old and one that I will pass on to my grandchildren in the future.
Solution: Positive
