Input: Consider Input:  "process paragraph : : Magma is formed when rock melts inside the Earth's crust. Magma rises. Collects inside magma chambers underneath a volcano. Pressure builds in the magma chambers as they fill. Gain energy for eruption. Some of the energy is converted into seismic activity (earthquakes). If the magma building in the volcano is thick and sticky it will trap gases. Results in an explosive eruption when the pressure becomes too intense. If the magma is thin and runs. The magma results in a low-pressure, slow-moving flow of magma instead of a violent eruption. ", "event : Magma rises.", "entity : volcano" 

Output:  unknown location 


Input: Consider Input:  "process paragraph : : Water comes into contact with something made of iron. The water combines with carbon dioxide in the air to form carbonic acid. As the acid is formed, the iron starts to dissolve. Some of the water breaks down into hydrogen and oxygen. The free oxygen and dissolved iron bond together. They form iron oxide, which is rust. ", "event : The water combines with carbon dioxide in the air to form carbonic acid.", "entity : water" 

Output:  unknown location 


Input: Consider Input:  "process paragraph : : Food enters the mouth. Food mixes with saliva. Food is swallowed. Enzymes in the stomach break down the food. The food moves to the small intestine. Hormones from the pancreas move to the small intestine. The hormones create the amount of sugar in the blood from the food. The sugar in the blood travels to the body. The sugar provides energy for the muscles. ", "event : Food mixes with saliva.", "entity : food" 


Output:  known location
