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.

Question:  "process paragraph : : The organism must die to begin the process. The soft tissue decomposes. The bones are left behind. Scavengers tear the body apart and move the bones elsewhere. Wind and rain also scatter the bones further. The bones left behind will weather and become buried by sand and soil. The proteins in the bone are replaced with minerals that are dissolved in the soil. This creates a rock-like substance called a fossil. Water and wind erosion wear away the layers of soil on top of the fossil. This makes discovery of the fossil possible. ", "event : The soft tissue decomposes.", "entity : organism" 

Answer:  not exist 


Question:  "process paragraph : : An area is at a higher elevation than the surrounding area. Rain falls. Water is in the area of high elevation. The water creates a stream. The stream moves towards lower elevation. The stream continues along the same path for a long time. The soil and rocks erode where the stream touches them. The stream moves deeper into the soil. The stream is smaller than the eroded area. ", "event : Rain falls.", "entity : rain" 

Answer:  not exist 


Question:  "process paragraph : : Carbon dioxide enters the leaf through the stomates. Water is absorbed by the plant and transported to the leaves. Sunlight is captured by the plant. Energy in the form of ATP is made from the sun's energy. Carbon dioxide, water, and ATP form sugars via the Calvin cycle. Oxygen is given off as a byproduct. Oxygen leaves the leaf through the stomates. Water is reused or it leaves the leaf. The sugars can be used by the plant to make cellulose. ", "event : Water is absorbed by the plant and transported to the leaves.", "entity : atp" 

Answer:
 not exist
