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: We purchased this for use in a first-grade classroom. After reading the reviews and descriptions we ordered this tape. On receiving it we found that every participant needs a set of dumbbells and ankle weights. Nowhere did we see indications that additional additional equipment was needed. We are now deciding whether to return this tape unopened. Please be aware that this tape is of dubious benefit unless you have access to dumbbells (the bar-bell type, not the student type) and ankle weights.
Output:
Negative
