Fact 1: Abattery converts chemical energy into electrical energy.

Fact 2: If we disconnect the battery, the flow of electrons is no longer driven by the chemical forces in the battery.

Given the two facts above, answer the question "what produces a flow of electrons" with the following options: 
- direct energy
 - jumping
 - the wire
 - a shoe
 - rays or beams
 - Light
 - a battery
 - energy
