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 : : Rock begins as magma from a volcano. The magma cools. Crystals form and the magma become igneous rocks. The igneous rocks break down into sediment. Become sedimentary rocks. If subjected to heat and/or pressure from plate-tectonic activity the sedimentary rocks become metamorphic rock. The metamorphic rocks melt. Become magma again. ", "event : The magma cools.", "entity : magma" 

Output:  unknown location 


Input: Consider Input:  "process paragraph : : The butterfly starts as an egg. The egg hatches to form a larva, also called a caterpillar. The carterpillar molts (loses its skin) many times as it grows. The caterpillar then forms itself into a pupa, or chrysalis. The caterpillar in the chrysalis begins change, a process called mmetaphorphosis. The caterpillar completes its metamorphosis and has turned into a butterfly. The adult butterfly emerges out of the chrysalis and flys away!. ", "event : The egg hatches to form a larva, also called a caterpillar.", "entity : egg" 

Output:  not exist 


Input: Consider Input:  "process paragraph : : Wind and water erode rocks. The wind and water pick up sediment that came off the rocks. Sediment is carried to an area by the wind, water, air, or ice. Sediment is deposited on the same spot many times. The sediment piles on top of other sediment for a long time. The sediment near the bottom is compressed by the weight of newer sediment. The sediment becomes sedimentary rock as it is pushed together by the heavy weight. ", "event : The wind and water pick up sediment that came off the rocks.", "entity : rocks" 


Output:  unknown location
