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.

This is one of the worst books ever. It tries to capitalize on the Chicken Soup for the Soul-type, void of any substance stories. This was not written by the author and takes advantage of people around her by publishing stories from them. With no new insight, Samira, a strictly amateur writer, doesn't contribute anything. Fortunately, it's by a vanity publisher and the only people who buy it are her friends (who posted here from "Grand Blanc" and "Michigan" because Samira asked them to) and a few people who found it online. Please people, avoid this book, buy something that will be worth your time and money.
Output:
Negative
