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 : : Place the water in a pot. Cover the pot with a slightly too large cover. Place a larger pot under the first. Heat water to evaporation. Water vapor will collect on the lid. Drip into the second pot as fresh water. Salt is left behind in the original pot. ", "event : Cover the pot with a slightly too large cover.", "entity : water" 

Output:  known location 


Input: Consider Input:  "process paragraph : : Plants obtain water through the soil they are growing in. The plants roots absorb the water from the soil. Transport the water to the parts of the plant where the water is needed. The plant uses the water as part of the photosynthesis process. The plant creates food, called glucose, for itself. The plant uses water to circulate the glucose around the plant to deliver the glucose to where it's needed. ", "event : The plants roots absorb the water from the soil.", "entity : water" 

Output:  known location 


Input: Consider Input:  "process paragraph : : Human beings burn fossil fuels (oil, gas, etc.). Carbon dioxide from the burning fossil fuels enter the atmosphere. The make-up of the atmosphere changes. Some energy from the sun cannot escape back through the changed atmosphere. The earth begins to heat because of the extra trapped energy. Human beings cut down trees. Human beings do not re-plant the trees. Trees cannot help take the extra carbon dioxide from the atmosphere. The extra trapped energy starts to change the earth's short term weather. Eventually the long-term climate patterns start to change. ", "event : Carbon dioxide from the burning fossil fuels enter the atmosphere.", "entity : fossil fuels" 


Output:  not exist
