You will be given a definition of a task first, then some input of the task.
Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.

I dropped my first Kindle on a hard subway seat. It was only an 18 inch fall, but it destroyed the ability to make letters. I turned it in for a replacement, still the #1. It remains inseparable. I have somewhat deficient sight, and Kindle has given me access to large books I never could get through becuase I would have to hold them close. It has returned me to extensive reading that I thought I no longer could do. The cover doesn't work too well, and the illustrations are faint, but no matter.
Output:
Positive Review
