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 used to think that there was no strategy, per se, to fishing a lake--a big tub of water you trolled until you got an arbitrary hit.This book takes an almost forensic view of a lake's features--water layers, vegetation, etc.--and shows how to read them and catch fish. It's much more detailed than I expected and I came away with a real sense of how to find trout as quickly as possible.
Output:
Positive
