Coal fired power plants are used to create the electricity that we depend on. However, they also release a lot of pollution into the atmosphere through their giant smokestacks.
After a new plant was built in Jackson, residents noticed that the statue in the town square had started to fall apart or corrode, and that this was especially noticeable after a rain storm.
What might explain the statue's corrosion?
A) The statue is exposed to wind and sun.
B) Someone is probably vandalizing the statue when no one is looking.
C) The statue is probably old enough to start breaking down on its own.
D) The smoke from the plant mixes with water vapor in the air, creating acid rain.
