You will be given a definition of a task first, then some input of the task.
Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

My review is not about the book. This is one of my textbooks I needed for my course and I was glad that Amazon had it in stock. However I chose to pay highest shiping amount to express delivery for next day, (which happens to be Saturday) so that I have time to review chapter before school started, it did not arrive that Saturday. What is purpose was next day delivery if you don't receive the product on time? I think I paid about $25 for one book when there was an option to receive Monday delivery for much less ($10, I think). The book arrived on Monday after my school started and I did not have a book to take to school. Amazon owes me money!
Output:
Negative
