Storm Drains    
So, what is a storm drain anyway?    
  1. Like when you get tired after running in the rain.

  2. Basically an underground trash can where you can put trash.

  3. Part of a system of waterways that drains rainwater into our streams and oceans.
If you think about it, everything that goes into the storm drain goes straight to where I live. So it's important to keep storm drains free of rubbish. After all, you wouldn't want me putting my rubbish in your home, would you?  
The correct answer is C.
