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 : : Warm water rises off the seas. The water condenses as it cools and gets higher in the air. Then the condensation forms into clouds. The clouds travel over areas on land. The clouds reach a saturation point. The rain falls from the clouds. ", "event : The water condenses as it cools and gets higher in the air.", "entity : warm water ; water" 
Example Output:  known location 

Example 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" 
Example Output:  unknown location 

Example Input:  "process paragraph : : Warm air rises. Then it expandes and cools. Some of the vapor condenses onto tiny pieces of dust that are floating in the air. Forms a tiny droplet around each dust particle. Billions of these droplets come together they become a visible cloud. ", "event : Then it expandes and cools.", "entity : warm air" 
Example Output:
 not exist
