Example:  "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" 
Example solution: known location
Example explanation: The process paragraph explains in steps about - the cause for volcano eruption. The event is a part of the process paragraph given. The entity lies both in process paragraph and the event. So, this is a good example.

Problem:  "process paragraph : : Living things have carbon in them. Living things die. The remains of living things eventually become buried underground. More physical pressure is put on the remains of living things as they become further underground. This carbon-based mixture stays underground for a long time. Humans discover this carbon-based mixture. This carbon-based mixture is brought up to the earth's surface. The recently discovered fossil fuel is burned. Burning releases the energy that has been stored in the fossil fuel. The energy can be used to generate power. ", "event : Living things die.", "entity : living things ; remains of living things" 

Solution:  unknown location
