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. 

Input: Consider Input:  "process paragraph : : Magma is formed when rock melts inside the Earth's crust. Magma rises. Collects inside magma chambers underneath a volcano. Pressure builds in the magma chambers as they fill. Gain energy for eruption. Some of the energy is converted into seismic activity (earthquakes). If the magma building in the volcano is thick and sticky it will trap gases. Results in an explosive eruption when the pressure becomes too intense. If the magma is thin and runs. The magma results in a low-pressure, slow-moving flow of magma instead of a violent eruption. ", "event : Magma rises.", "entity : volcano" 

Output:  unknown location 


Input: Consider Input:  "process paragraph : : Electromagnet creates magnetic field with electricity. Conductive copper wire is wrapped around a piece of metal. An electric current gets introduced from power source. Flows through the wire. Magnetic field gets created in the wire. And the metal gets magnetized. When turned off it is no longer magnetic. ", "event : Conductive copper wire is wrapped around a piece of metal.", "entity : magnetic field" 

Output:  known location 


Input: Consider Input:  "process paragraph : : Nitrogen-fixing bacteria convert atmospheric nitrogen to organic nitrogen. Plants absorb organic nitrogen from the soil through their roots. Animals eat the plants. Plants and animals die. Animals expel wastes. Fungi convert organic nitrogen to ammonium. Nitrifying bacteria convert ammonium to nitrate. Bacteria convert nitrate to nitrogen gas. Nitrogen gas escapes from soil into the atmosphere. ", "event : Plants absorb organic nitrogen from the soil through their roots.", "entity : atmospheric nitrogen" 


Output:  not exist
