input: Please answer the following: - A fuel is heated in an oven - Above the oven is a tank of water that is sealed - The tank of water begins to boil above the oven - A the water boils steam is created - The steam is denser than air so it needs a place to go - The steam is forced out of the tank and into a piston - The piston moves up - The valve of the piston closes - The valve on the next piston opens What might be the last step of the process?
++++++++++
output: The steam fills the next piston, driving it up, and the other one down
Please answer this: - Water in the clouds becomes very cold - The cold water forms ice crystals - The ice crystals grow by absorbing surrounding water droplets - Form snowflakes What might be the last step of the process?
++++++++
Answer: The snowflakes fall to the ground.
Problem: - When water freezes it becomes 10% bigger, or takes up 10% more space - As water expands it puts great pressure on the walls of anything containing it, including any rocks which happen to be surrounding it - The force of the pressure exerted on the rock surrounding it is enough to wedge the walls of the crack farther apart, thus expanding and deepening the crack - Clay expends when wet like ice does - This causes rock to break apart - Some plants like mosses and lichens are capable of growing without soil on bare rock What might be the last step of the process?

A: When they do this their roots penetrate pores and crevices and cause rocks to split apart as the roots force their way down through the rocks
Problem: Given the question: - Coal is harvested from a coal mine - The coal is transported either by train or truck to power station - The coal is burned in a furnace - Water is turned into steam in the boiler - The steam is cooled in cooling towers - The steam turns the turbines - The generator makes electricity What might be the last step of the process?
++++++++++++++++++++++++++++++++
The answer is:
The electricity is sent through transformers.
input question: - 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 answer: Become magma again.
input question: - Animals and plants die in soft soil or mud - Sediment builds up over the remains - The remains decompose, leaving only trace amounts - The remaining parts over the years are replaced with mineral What might be the last step of the process????
output answer:
A fossil is formed
