++++++++++
output: The carbon atoms rearrange to become a new substance.

Please answer this: What is the final step of the following process: - 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
++++++++
Answer: They form iron oxide, which is rust

Problem: What is the final step of the following process: - A star forms - The star does not have enough mass to become a neutron star - The star goes through a change in its core and bonds helium to carbon and oxygen - The star becomes a red giant - A mass of carbon and oxygen builds up in the center of the star - The star sheds its outside layers and becomes a nebula

A: The star leaves behind the core which becomes a dwarf star.

Problem: Given the question: What is the final step of the following process: - Coal is mined out of the ground - Coal is pulverized into fine powder - The coal is mixed with hot air - The coal and hot air are blown into a boiler - The coal and hot air burn over a fire - Highly purified water is pumped through pipes in the boiler - The water turns into steam - The steam presses against turbines - The turbines spin
++++++++++++++++++++++++++++++++
The answer is:

input question: What is the final step of the following process: - Muscles work by expanding and contracting - A muscle fiber gets a signal from its nerve - Proteins and chemicals release energy to either contract the muscle or relax it - When the muscles contracts the bones connected to he muscle are pulled closer together???
output answer: When the muscle relaxes the bones move farther apart.

input question: What is the final step of the following process: - The air is cold - Water is in the air - The water forms tiny ice crystals - The ice crystals collide with each other - The ice crystals stick to each other - The ice crystals get bigger as more of them stick together - The ice crystals get too heavy to be in the air - The ice crystals become snowflakes???
output answer:
The snow flakes fall to the ground as snow.
