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'.

This item did not work. It came with no instructions but it seemed obvious that it needed to be exposed to the sun to charged. After 4 days in full sun, when I plugged in my iPhone, then my kindle, nothing happened. I sent it back for a refund.
Output:
Negative Review
