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 mouse is terrible. At random intervals it will 'stop working' and you find yourself scrubbing it over the mousepad in utter frustration, trying to find the cursor, only to see it frozen... sometimes it will start up again other times you have to turn it off and on again to get it to reconnect. I suspect they either low-balled the power budget so bad that the least amount of interference knocks the BlueTooth connection out or their firmware internally is hung. Either way it seems to be a poor piece of engineering. That and the 'simulated' wheel they have built into it does NOT respond like a real mouse wheel at all.
Output:
Negative Review
