Given the task definition, example input & output, solve the new input case.
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
Output: Negative
Review writer does not like the book because it was boring, therefore it is a negative review.

New input case for you: I loved reading Dale Carnegie's books since I picked up How to Win Friends and Influence People. His writing style is very easy to read and he is always giving examples to make the content as clear as possible. That being said, The Quick and Easy Way to Effective Speaking is a great book. I personally preferred How to Win Friends and Influence People over this book, so if you have not read that book, I would recommend reading it first. However, if you are specifically looking for a book on Public Speaking, Dale Carnegie is a great author and he has several books about this topic. This one is great and I recommend it.
Output:
Positive
