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.

Although though we're (presumably) members of the same political choir, the author treats economics much too simplistically.Calling this book a polemic on Keynesian economics would be accurate, calling it an economics treatise would be just plain wrong.Time would be better spent reading Bastiat.
Output:
Negative
