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 : : Water is introduced to carbon dioxide. The water becomes acidic. The water seeps down to a mineral based material. The acidity of the water carves and shapes the rock. And may form geological phenomenon. ", "event : The water becomes acidic.", "entity : water" 

Output:  unknown location 


Input: Consider Input:  "process paragraph : : Information encoded in DNA is copied to a RNA molecule. The mRNA molecule is sent to the cytoplasm. The mRNA bonds with ribosomes. TMRNA molecules bind with the ribosome in a sequence defined by the mRNA code. The ribosome slides down the mRNA. The process continues until one of the stop codons enters the A site. ", "event : The mRNA molecule is sent to the cytoplasm.", "entity : DNA" 

Output:  known location 


Input: Consider Input:  "process paragraph : : Prophase, the chromosomes become visible. Centrioles separate to move to opposite poles. Metaphase, the chromosomes line up in the center. Anaphase, the chromatids separate. Are pulled apart. Telophase, the chromosomes gather at opposite poles. Two new nuclear membranes form. The cell membranes pinch. Divide into two individual cells. ", "event : Centrioles separate to move to opposite poles.", "entity : chromosome" 


Output:  unknown location
