You are presented with the question "powering an electrical device with a battery requires a path for electrons to what?" and the following answer choices: 
- hydrogen and oxygen
 - spread out
 - electromagnetic energy
 - cut the line
 - flow continuously
 - an electron microscope
 - flood
 - kinetic energy

Now knowing that powering an electrical device with a battery requires a path for electricity to flow through a closed circuit and electrons flow continuously in a closed circuit, choose the best answer.


 

     flow continuously
