Ex Input:
 "process paragraph : : A reservoir is formed. The collects water converting the water's from kinectic to potential. The water is forced through a turbine under the reservoir. The turbine spins and so does the generator connected to it. The water's energy is turned into electrical energy. The transformer converts electrical energy from the generator to a high voltage. The national grid uses high voltages to transmit electricity through the power lines. ", "event : The collects water converting the water's from kinectic to potential.", "entity : reservoir" 

Ex Output:

 unknown location
