In this task, you are given a paragraph, event and an entity. The event is part of the given paragraph and it changes the state of the entity. Your task is to classify the state of the entity into three classes: 1) not exist, 2) unknown location and 3) known location. "not exist" means the entity doesn't exist in that state anymore. "unknown location" means the entity exists in that state but location is unknown. "known location" means the entity exists and location is known. 

Example Input:  "process paragraph : : An organism dies. Water seeps into the remains. Minerals dissolved in the water form crystals. Crystalized minerals cause the remains to harden. The minerals form a fossil. ", "event : Water seeps into the remains.", "entity : organism" 
Example Output:  not exist 

Example Input:  "process paragraph : : A fuel goes into the generator. The generator converts mechanical energy into electrical energy. A magnet moves near a wire. A steady flow of electrons is C. Electricity flows through a wire. Electricity comes out of the generator. ", "event : The generator converts mechanical energy into electrical energy.", "entity : fuel" 
Example Output:  not exist 

Example Input:  "process paragraph : : Sunlight hits chloroplasts in the plant. The energy from the sunlight causes an enzyme in the plant to break apart the water. The water breakes into oxygen, hydrogen, and electrons. Hydrogen, along with electrons energized by light, converts NADP into NADPH. Oxygen diffuses out of the plant as a waste product of photosynthesis. ", "event : The energy from the sunlight causes an enzyme in the plant to break apart the water.", "entity : energy" 
Example Output:
 not exist
