Example Input: El primer libro del Dr. Weiss sigue siendo un gran libro para todos aquellos a quienes les inquieta el tema de la reencarnación, así no crean en ella.
Example Output: Positive

Example Input: Good quality overall. The braket for the stem didn't fit my application, so I improvised, and mounted it behind the seat over the rear fender and low. Holds stuff.
Example Output: Positive

Example Input: I've had the P1000 for a couple of years. Worked great with WindowsME. After installing XP on my desktop I had to reinstall the printer software to get it to work. Just got a new laptop and it doesn't work at all.. in fact, the P1000 causes my Dell Inspiron to crash whenever I disconnect the USB cable. When the cable is connected the laptop never recognizes the printer.
Example Output:
Negative
