Fact 1: When an electrical circuit is working properly , electrical current runs through that circuit.

Fact 2: Electrical circuits require a complete loop through which the electrical current can pass.

Given the two facts above, answer the question "What does electricity need to do to work properly?" with the following options: 
- absorb light energy
 - heat is produced
 - Have access to air
 - Submerged in water
 - Be plugged in
 - Complete a loop in a circuit
 - it keeps an organism warm
 - Burning fuel and air
