input question: - Boil salt water - The water will turn into water vapor - Collect the water vapor - Allow the water vapor to cool - The water vapor will turn into liquid water What might be the last step of the process????
output answer: The salt will be separated from the water.

input question: - Solution caves are formed in limestone and similar rocks by the action of water - After a rain, water seeps into cracks and pores of soil and rock - The water percolates beneath the land surface - Some of the water reaches a zone where all the cracks and pores in the rock are already filled with water - Rainwater absorbs some carbon dioxide as it passes through the atmosphere and even more as it drains through soil and decaying vegetation - The water combines chemically with the carbon dioxide - A weak carbonic acid solution is formed What might be the last step of the process????
output answer: This acid slowly dissolves calcite, forms solution cavities, and excavates passageways

input question: - Electromagnet creates magnetic field with electricity - Conductive copper wire is wrapped around a piece of metal - An electric current gets introduced from power source - Flows through the wire - Magnetic field gets created in the wire - And the metal gets magnetized What might be the last step of the process????
output answer: When turned off it is no longer magnetic.

input question: - Coal is put in a coal-fired steam station - Water is put in pipes in the coal-fired steam station - The coal is crushed - The coal is moved into a boiler along with hot air - The water is moving through pipes in the boiler - The steam from the water is blown against a turning mechanism - The force of the steam makes the mechanism turn What might be the last step of the process????
output answer:
The mechanism generates electricity.
