Think of a circuit as a flow of electrons. As a switch is flipped on, electrons flow from the switch. What happens when they reach a gate? Trace the path of the current around the circuit.

This problem involves the sort of thinking typically found formally in Decision Mathematics modules, but can be attempted armed only with a basic understanding of logic and truth tables.
