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:  "process paragraph : Magma rises from deep in the earth. The magma goes into volcanos. The volcanos pressure the magma upwards. The pressure causes the magma to push through the surface of the volcano. The lava cools. The lava forms new rock. New magma is pressured to the surface of the volcano. The volcano bursts through the rock the formed after the last eruption" , "event : Magma rises from deep in the earth" , "entity : magma" 
Example solution: known location
Example explanation: The process paragraph explains in steps about - the cause for volcano eruption. The event is a part of the process paragraph given. The entity lies both in process paragraph and the event. So, this is a good example.

Problem:  "process paragraph : : The magma comes out from a volcano. The magma cools and becomes a rock. Over time the rock picks up sediment which changes the type of rock. This creates a sedimentary rock. The heat from inside and outside can cook a rock. This heat forms a third kind of rock. The cycle continues around the three types of rocks. ", "event : The magma cools and becomes a rock.", "entity : magma" 

Solution:  not exist
