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 : : Fans blow air onto the evaporator's coils. The refrigerant within the coils absorbs the heat. The refrigerant changes from a liquid to a gas. The compressor compresses the gas, increasing the pressure. The hot, pressurized gas moves to the condenser. The gas condenses in the condenser and becomes a liquid again. Heat is radiated away from the condenser. The cooled liquid is returned to the evaporator. ", "event : The refrigerant within the coils absorbs the heat.", "entity : Air" 

Output:  known location 


Input: Consider Input:  "process paragraph : : Cells obtain glucose and oxygen. The glucose and oxygen create carbon dioxide. The cells release energy. The cells don't have enough oxygen to repeat this. The cells obtain more oxygen from the air. The cells repeat this process. ", "event : The glucose and oxygen create carbon dioxide.", "entity : glucose and oxygen" 

Output:  not exist 


Input: Consider Input:  "process paragraph : : Wind and water cause erosion and weathering to the rocks. Eroded rock particles are carried away by wind or by rain, streams, rivers, and oceans. Rock particles sink to the bottom of rivers and oceans creating a layer of sediment. Layers of sediment stack up compacting the bottom layers. Minerals fill in the gaps in the sediment eventuality becoming sedimentary rocks. Rocks buried deep underground exposed to high heat and pressure become metamorphic rock. Metamorphic rocks underground melt to become magma. Magma flows from volcanoes in the form of lava. Lava cools and forms igneous rock. Igneous rock begins being weathered and eroded by water and wind. ", "event : Eroded rock particles are carried away by wind or by rain, streams, rivers, and oceans.", "entity : rocks" 


Output:  unknown location
