PROBLEM:  "process paragraph : : Carbon dioxide passes through stomata in the leaves. Water is absorbed through roots. Chloroplast cells in leaves contain chlorophyll. Chlorophyll absorbs energy from sunlight. Energy splits water molecules into hydrogen and oxygen. Oxygen gets released into atmosphere. Hydrogen and carbon dioxide used to create glucose. Glucose is food for plants. ", "event : Water is absorbed through roots.", "entity : energy" 

SOLUTION:  known location 

PROBLEM:  "process paragraph : : Energy is created by burning either diesel or petrol in a combustion chamber. The energy is transferred from the pistons moving up and down at high speeds. This piston motion is converted to a rotary motion through the crankshaft and axle. The axle turns the wheels. The car moves forward. ", "event : The energy is transferred from the pistons moving up and down at high speeds.", "entity : diesel" 

SOLUTION:  not exist 

PROBLEM:  "process paragraph : : A tree produces seeds. The seeds are dispersed by wind, animals, etc. The seeds reach the ground. Grow into new trees. These new trees produce seeds. The process repeats itself over and over. ", "event : The seeds are dispersed by wind, animals, etc.", "entity : Tree"
