Fill in the blank with one of the two choices. For electricity to flow in a circuit, it must be a complete full loop. Switches can open to break the circuit or close to complete the circuit. If a switch is open making a gap in the circuit, electricity ________________ flow.

Btw there are no choices and I honestly have no idea what this answer is.
Please help!

If a switch is open and there is a gap in the circuit, electricity cannot flow.
