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.

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
