Task: Story Composition
Input (English): Background Paragraph: Iron is first oxidized to iron(II) ions by oxygen. In the second step, the iron(II) ions are further oxidized and combine with water and oxygen gas to produce a hydrated form of iron(III) oxide known as rust. Rusting is one of many example of corrosion. Corrosion is the deterioration of metals by redox processes. Corrosion causes enormous amounts of damage to buildings, bridges, ships, cars, and other objects. It has been estimated that corrosion costs the U.S. economy over 100 billion dollars each year. A great amount of time and effort is spent to try to limit or prevent corrosion.
Output (English): Jordan is conducting an experiment to see how Iron rusts. He first takes Iron Bar A and puts it out on his porch on a rainy day. Then he puts Iron bar B in an airtight bag and removes all of the oxygen and air to vacuum seal it. After some time passes the bar he left outside is completely covered in rust. He removes the bar in the vacuum sealed bag and to his surprise it has no rust at all. Because there was no oxygen and water in the air tight bag, iron bar B has no rust at all. Iron bar A was exposed to a lot of water and oxygen and there for it rusted completely.
