Question: -  A machine called a pulverizer grinds the coal into a fine powder - The coal powder mixes with hot air, which helps the coal burn more efficiently, and the mixture moves to the furnace - The burning coal heats water in a boiler, creating steam - Steam released from the boiler powers an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine - The spinning turbine is used to power a generator, a machine that turns mechanical energy into electric energy - This happens when magnets inside a copper coil in the generator spin - A condenser cools the steam moving through the turbine - As the steam is condensed, it turns back into water  What might be the last step of the process?
Answer: The water returns to the boiler, and the cycle begins again
[Q]: -  An enzyme in saliva begins to break down carbohydrates - Food is squeezed down the esophagus when you swallow - Acid and enzyme in the stomach break the food down - Releases nutrients - Food then pumped into small intestine - Fluid and enzymes from liver and pancreas pumped into small intestine - Help break food into smallest molecules - Nutrients pass through wall of small intestine - Nutrients absorbed into blood stream  What might be the last step of the process?
****
[A]: Unused materials passed into large intestine to become fecal matter.
input: Please answer the following: -  Rock begins as magma from a volcano - The magma cools - Crystals form and the magma become igneous rocks - The igneous rocks break down into sediment - Become sedimentary rocks - If subjected to heat and/or pressure from plate-tectonic activity the sedimentary rocks become metamorphic rock - The metamorphic rocks melt  What might be the last step of the process?
++++++++++
output: Become magma again.
Please answer this: -  Carbon dioxide enters the leaves through the stomates by diffusion - Water is transported to the leaves in the xylem - Energy harvested through light reaction is stored by forming ATP - Carbon dioxide and energy from ATP are used to create sugar - Oxygen exits the leaves through the stomata by diffusion  What might be the last step of the process?
++++++++
Answer: The plant reuses the water or the water exits through the stomata as water vapor.
Problem: -  Body temperature rises - The brain tells blood vessels to dilate - The sweat glands become active - Moisture is released from the pores - The moisture evaporates  What might be the last step of the process?

A: The evaporation causes cooling.
input: Please answer the following: -  Dead organic material accumulates on the bottom of oceans, riverbeds or swamps, mixing with mud and sand - Over time, more sediment piles on top - The resulting heat and pressure transforms the organic layer into a dark and waxy substance known as kerogen - Left alone, the kerogen molecules eventually crack - The molecules break up into shorter and lighter molecules composed almost solely of carbon and hydrogen atoms  What might be the last step of the process?
++++++++++
output:
It will turn into either petroleum or natural gas
