Definition: 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.

Positive Example 1 -
Input: "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"
Output: known location

Positive Example 2 -
Input: "process paragraph : Water from the ocean washes onto beaches in waves. The waves contain sediment from the ocean. The water and particles in it hit rocks and sand on the beach. The wind and current sometimes push the water and particles harder. Tiny parts of the rocks on the shore come off the larger rocks. The waves pick up sand and small rocks from the beach. The waves go back out into the ocean. The waves carry the new particles with them. Rocks and the beach look a little different. ", "event : The waves go back out into the ocean. ", "entity : waves"
Output: known location

Negative Example 1 -
Input: "process paragraph : Water from oceans, lakes, swamps, rivers, and plants turns into water vapor. Water vapor condenses into millions of tiny droplets that form clouds. Clouds lose these droplets through rain or snow, also caused precipitation. Precipitation is either absorbed into the ground or runs off into rivers. Water that was absorbed into the ground is taken up by plants. Plants lose water from their surfaces as vapor. The vapor goes back into the atmosphere. Water that runs off into rivers flows into ponds, lakes, or oceans. The water evaporates back into the atmosphere. ", "event : Water from oceans, lakes, swamps, rivers, and plants turns into water vapor. ", "entity : water"
Output: known location

Negative Example 2 -
Input: "process paragraph : Magma rises to the surface during a volcano. The magma undergoes changes in temperature. The magma undergoes changes in pressure. The magma cools. The magma solidifies. The magma crystallizes. Igneous rock is formed. ", "event : Magma rises to the surface during a volcano. ", "entity : magma"
Output: unknown location

Now complete the following example -
Input: "process paragraph : : The animal eats large quantities of food that will be stored as fat. Winter comes and the animal finds a place to hibernate. Over a period of days, the animal's heart rate and breathing rate drop slowly. Electrical activity in the brain almost ceases completely, though some areas remain active. The animal has entered hibernation mode. ", "event : Winter comes and the animal finds a place to hibernate.", "entity : food"
Output: 


Answer:  not exist
