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: Was a little tricky without instructions but I figured it out....however, will not work on the bike as the brackets are too thick to slide over the wheel bolts and leave enough room for the frame to be reattached. Returning it
Solution: Negative
